Every click on your Google Ads costs money. But what if you could identify exactly which clicks are draining your budget and prevent them from ever happening again? IP address blocking is the digital equivalent of a bouncer at an exclusive club—keeping out the troublemakers while letting genuine customers through.
Yet here's the uncomfortable truth most fraud protection services won't tell you: IP address blocking alone stops less than 30% of sophisticated click fraud. Traditional approaches to IP blocking create a false sense of security while 70%+ of fraud slips through undetected. The fraudsters have evolved. The protection methods must evolve too.
This comprehensive guide reveals everything about IP address blocking in Google Ads—what it is, why it works, where it fails, and most critically, how to implement it as part of a multi-layered defense system that actually protects your advertising budget in 2027's sophisticated fraud landscape.
Understanding IP Addresses: The Foundation
Before mastering IP blocking strategy, you need to understand what you're actually blocking and why it matters.
What Is an IP Address?
An Internet Protocol (IP) address is a unique numerical identifier assigned to every device connected to the internet. Think of it as a digital street address—just as mail needs a physical address to reach your home, data packets need an IP address to reach your device.
IP addresses look like this: 192.168.1.1 (IPv4 format) or 2001:0db8:85a3:0000:0000:8a2e:0370:7334 (IPv6 format).
Every time someone clicks your Google Ad, their device's IP address is recorded. This creates a traceable digital footprint connecting that click to a specific internet connection—whether it's a home network, office, mobile carrier, or data center.
Static vs. Dynamic IP Addresses
Understanding IP address types is critical to effective blocking strategy:
- Static IP Addresses remain constant over time. Larger organizations, businesses with dedicated internet connections, and some residential users have static IPs that don't change for months or years. These are ideal blocking targets—once you identify a static IP as fraudulent, blocking it provides long-term protection.
- Dynamic IP Addresses change periodically—sometimes daily, weekly, or monthly depending on the Internet Service Provider (ISP). Most residential users and mobile devices have dynamic IPs. This creates the primary limitation of IP blocking: the fraudulent IP address you block today may belong to a legitimate customer tomorrow.
Research shows that 77% of IP addresses are retained for less than one week, while only 45% of ISPs allow keeping the same IP for more than 30 days. This means that the majority of IPs you block will eventually be reassigned to different users, making permanent IP blocking problematic.
IP Ranges and Subnets
Individual IP addresses aren't random—they're organized into ranges called subnets. Understanding this structure unlocks powerful blocking capabilities:
IP Range Example: 192.168.1.0 through 192.168.1.255 represents a subnet of 256 IP addresses (0-255 in the final section).
When fraud originates from a specific organization, data center, or geographic region, blocking the entire IP range is more effective than blocking individual addresses. Google Ads supports range blocking using wildcards: 192.168.1.* blocks all 256 addresses in that range.
Strategic Advantage: If you identify a data center hosting bot networks at IP 103.21.244.15, blocking 103.21.244.* prevents 256 potential bot IPs from that facility from accessing your ads. This proactive approach stops fraud before it scales.
How IP Addresses Connect to Click Fraud
Click fraud operates through identifiable IP patterns:
- Repeated Clicks from Single IPs: When one IP address clicks your ads 10, 20, or 50 times within hours, that's almost certainly fraud—either a competitor, bot, or click farm attacking your budget.
- Data Center IPs: Legitimate customers use residential or mobile ISPs. Traffic from data center IPs (hosting providers, cloud services) indicates bot networks or fraudulent operations.
- Geographic Anomalies: Clicks from regions with no connection to your business—a Dallas plumber getting clicks from Indonesia—signal fraud that IP-based geographic analysis can detect and block.
- VPN and Proxy Usage: While some legitimate users employ VPNs for privacy, disproportionate VPN traffic often indicates fraud attempting to mask real locations.
IP addresses are the first layer of click fraud detection—visible, traceable, and actionable. The question isn't whether to use IP blocking, but how to use it effectively as part of comprehensive protection.
Google Ads IP Exclusion: The Official Method
Google provides built-in IP exclusion functionality allowing advertisers to block specific addresses or ranges. Understanding exactly how this works is essential to using it effectively.
The 500 IP Address Limitation
Google allows blocking up to 500 IP addresses per campaign at the campaign level, plus an additional 500 at the account level. This sounds substantial until you realize there are approximately 4.3 billion possible IPv4 addresses.
The Math Problem: If click fraud attacks your campaigns using 1,000 different IP addresses (modest for organized fraud operations), Google's 500-IP limit blocks only half. If attackers use residential proxy networks rotating through millions of IPs, blocking 500 is like holding back a tsunami with a coffee cup.
This limitation forces strategic IP blocking—you must prioritize which IPs to block and regularly review and update your exclusion lists as new threats emerge and old IPs become inactive.
Account-Level vs. Campaign-Level Exclusions
Google offers two implementation levels:
- Account-Level IP Exclusions (added June 2024) apply across ALL campaigns in your account—Search, Display, Shopping, Performance Max, Discovery, Demand Gen, YouTube, and App campaigns. This provides comprehensive protection from known fraud sources across your entire advertising presence.
- Campaign-Level IP Exclusions apply only to specific campaigns. Use this for targeting flexibility—blocking IPs from certain campaigns while allowing them in others if there's strategic reason.
Best Practice: Use account-level exclusions for confirmed fraud sources (bots, click farms, known competitors) requiring universal blocking. Use campaign-level exclusions for nuanced situations like blocking your company's office IP from seeing recruitment ads while allowing it for product campaigns.
How to Implement IP Blocking in Google Ads
The mechanical process is straightforward:
- Sign into your Google Ads account at ads.google.com
- Navigate to Settings in the left-side menu
- For campaign-level blocking, select the specific campaign. For account-level blocking, access Account Settings
- Click "Additional Settings" to expand options
- Select "IP Exclusions" to open the blocking interface
- Enter IP addresses one per line in the format:
192.168.1.15 (specific address) or 192.168.1.* (entire range)
- Click "Save" to activate blocking
Result: Within minutes, your ads stop serving to those IP addresses across relevant campaigns.
Wildcard Blocking for IP Ranges
Google supports wildcard characters (*) to block entire IP ranges efficiently:
Example 1: 192.168.. blocks all IPs from 192.168.0.0 through 192.168.255.255 (65,536 addresses)
Example 2: 10.0.1.* blocks 10.0.1.0 through 10.0.1.255 (256 addresses)
Strategic Application: If you identify data center fraud from ASN (Autonomous System Number) 12345 operating in the 203.0.113.* range, one wildcard entry blocks 256 IPs instead of requiring 256 individual entries.
This multiplies your effective blocking capacity—the 500-IP limit becomes potentially millions of blocked addresses through strategic range blocking.
What Happens When an IP Is Blocked
Once blocked, users from that IP address cannot:
- See your ads in search results
- View your display ads on websites
- Encounter your video ads on YouTube
- Interact with your Performance Max or Discovery campaigns
Important: Blocking an IP address doesn't remove existing clicks or refund previously wasted spend. It only prevents future impressions and clicks from that source. IP blocking is preventive, not corrective.
The Time Element: How Long to Block
Google's IP exclusions remain active until manually removed. However, because IP addresses are often dynamic, permanent blocking creates problems:
The Dilemma: Block an IP indefinitely and you risk blocking legitimate customers who later receive that reassigned IP address. Remove blocks too quickly and fraudsters using that IP continue attacking.
Recommended Strategy: Block high-certainty fraud sources (data centers, confirmed bots, obvious competitor IPs) for 30-90 days, then review and refresh your exclusion list. For suspicious but uncertain IPs, use shorter 7-14 day blocking periods.
Advanced protection systems like ClickFortify automate this time-based management, blocking IPs for optimal durations then automatically releasing them before legitimate customers are impacted.
The Fatal Limitations of IP Blocking Alone
IP exclusion is valuable but insufficient. Understanding its limitations is essential to building effective fraud protection that actually works in 2027.
Limitation #1: Residential Proxy Networks
The click fraud industry has industrialized. Professional fraud operations don't use obvious data center IPs that are easy to identify and block. They use residential proxy networks—systems that route fraudulent clicks through real people's home internet connections.
How It Works: Fraudsters rent access to networks of compromised home routers, smart devices, or willing participants who sell their residential IP bandwidth. When a bot clicks your ad, it appears to come from a legitimate household IP in your target market—indistinguishable from real customers.
The Scale: Residential proxy networks provide access to millions of rotating IP addresses. Companies openly sell these services—brands like Bright Data (formerly Luminati) advertise "millions of residential IPs" for "data collection" that fraudsters exploit.
Detection Impossibility: A click from 192.168.1.15 in Dallas, Texas looks identical whether it's from a real homeowner or a bot routing through that homeowner's compromised router. IP address alone cannot distinguish between them.
The Result: Over 80% of fraudulent clicks now use unique residential IP addresses that won't repeat. Even if you could identify and block them (which you usually can't), they'll never attack again anyway—the next click uses a completely different residential IP.
This makes traditional IP blocking effectively useless against modern residential-proxy fraud.
Limitation #2: IP Rotation Speed
Even when fraud uses identifiable IPs (data centers, corporate networks), attack speed often exceeds blocking capability:
The Attack Pattern: Bot networks generate bursts of fraudulent clicks—sometimes hundreds within minutes. By the time you identify the pattern, review server logs, confirm it's fraud, access your Google Ads account, and add IPs to exclusion lists, the attack has already consumed significant budget.
Manual Blocking Failure: If fraud clicks occur at 100 per hour from rotating IPs, manual blocking is hopeless. You're perpetually behind, blocking yesterday's IPs while today's attacks continue uninterrupted.
The Math: With 500-IP limit and attacks using thousands of rotating IPs, you're blocking 10% while 90% continues. Even perfect IP identification can't overcome capacity constraints.
Only automated real-time blocking systems can match attack speeds. Manual IP blocking operates at human decision speed—far too slow for digital-speed fraud.
Limitation #3: The Legitimate Traffic Risk
Blocking IP addresses isn't risk-free. Overly aggressive blocking damages campaigns by excluding real customers:
- Shared IP Addresses: Mobile carriers often use carrier-grade NAT, meaning thousands of mobile users share one IP address. Blocking it excludes thousands of potential customers.
- Corporate Networks: Large companies route all employees through one or few IP addresses. Blocking a Fortune 500 company's corporate IP might exclude thousands of decision-makers.
- VPN and Privacy Users: Privacy-conscious legitimate customers increasingly use VPNs. Blocking common VPN IP ranges excludes these potential customers.
- False Positive Disaster: Block the wrong IP and you've just excluded your best customer, biggest client, or highest-value prospect. They'll never know why your ads disappeared—they'll just find a competitor instead.
Conservative blocking (only blocking obvious fraud) leaves you vulnerable. Aggressive blocking (blocking anything suspicious) risks excluding legitimate demand. This catch-22 makes IP blocking alone an incomplete solution.
Limitation #4: Device Fingerprint Permanence
IP addresses change; devices don't. When fraudsters rotate IP addresses, they often use the same devices—the same phone, laptop, or bot server clicking your ads from different IPs.
The Missed Opportunity: IP blocking catches the first attack from IP 203.0.113.25. The attacker switches to IP 198.51.100.50 and continues undetected. You block that new IP. They switch to 192.0.2.100 and attack again.
Meanwhile, it's the same device behind all three attacks. IP blocking forces you to play whack-a-mole with infinite moles. Device fingerprinting would block the device itself regardless of IP changes—but Google Ads IP exclusions can't do that.
Why This Matters: A competitor manually clicking your ads from their office might use a different IP (mobile data vs. office WiFi vs. home connection), but it's always the same hardware. IP blocking fails; device blocking succeeds.
Advanced fraud protection systems like ClickFortify combine IP blocking with device fingerprinting, creating persistent protection that survives IP changes.
Limitation #5: The False Security Trap
Perhaps the most dangerous limitation is psychological: IP blocking creates the illusion of protection while leaving campaigns vulnerable.
The Dangerous Mindset: "I blocked 500 suspicious IPs, so my campaigns are protected from fraud." Meanwhile, residential-proxy fraud, device-switching attackers, and sophisticated bots bypass those blocks entirely, continuing to drain budgets undetected.
The Visibility Gap: You see IPs you've blocked and feel accomplished. You don't see the fraud you're missing because it doesn't look different from legitimate traffic. The 70% of fraud bypassing IP blocks is invisible, creating false confidence in your protection.
The Opportunity Cost: Time and resources spent on manual IP management could be deployed on comprehensive fraud protection actually stopping sophisticated attacks.
IP blocking is a tool, not a solution. Treating it as comprehensive protection is like locking your front door while leaving windows open—you've done something, but you're still vulnerable.
ClickFortify: IP Blocking Done Right (Plus Everything Else)
Understanding IP blocking's limitations leads to an obvious question: If IP blocking alone isn't enough, what actually works? The answer is multi-layered protection combining IP intelligence with behavioral analysis, device fingerprinting, and machine learning—exactly what ClickFortify delivers.
Layer 1: Intelligent IP Analysis
ClickFortify doesn't just block IPs blindly. It analyzes IP intelligence comprehensively:
- Global IP Reputation Databases: Every click's IP is cross-referenced against global databases of known malicious IPs, bot networks, data centers, VPN providers, proxy services, and high-risk hosting providers.
- Real-Time IP Behavior Tracking: How the IP behaves matters as much as its identity. Does it generate clicks without conversions? Does it show impossible geographic movement? Does it exhibit bot-like patterns? ClickFortify's algorithms analyze behavior signals that static IP lists miss.
- ASN (Autonomous System Number) Analysis: IPs are organized into ASNs representing entire networks. If fraud comes from ASN 12345 (a known click farm hosting provider), ClickFortify can block the entire ASN proactively, preventing thousands of potential fraud IPs before they attack.
- Dynamic IP Rotation Detection: When an attacker rotates through multiple IPs, ClickFortify's pattern recognition identifies the attack campaign regardless of which specific IPs are used. This catches distributed attacks that individual IP blocking misses.
- Residential vs. Data Center Classification: ClickFortify distinguishes between residential IPs (legitimate customers) and data center IPs (likely bots), applying appropriate blocking strategies to each. Aggressive blocking for data centers; nuanced analysis for residential IPs.
- Time-Based IP Management: Automated blocking for optimal periods (typically 30-90 days), then automatic release before reassignment to legitimate users occurs. This prevents the "blocked legitimate customers" problem that manual IP management creates.
Layer 2: Device Fingerprinting Technology
Where IP blocking fails (device using multiple IPs), device fingerprinting succeeds:
- Multi-Dimensional Device Identity: ClickFortify creates unique fingerprints from dozens of device characteristics—screen resolution, installed fonts, browser plugins, WebGL rendering signatures, canvas fingerprints, audio context properties, timezone and language settings, hardware specifications, and more.
- Cross-IP Persistence: When a fraudster switches from one IP to another, ClickFortify recognizes it's the same device and maintains the block. The attacker must change devices, not just IPs, to bypass protection.
- Device-Based Exclusions: ClickFortify automatically creates device-based audience exclusions in Google Ads. These persist across IP changes, maintaining protection even as attackers rotate through different networks.
The Multiplicative Effect: IP blocking alone catches maybe 30% of fraud. Add device fingerprinting and you catch the 40% that uses IP rotation. Now you're at 70% fraud detection—more than doubling effectiveness.
Layer 3: Behavioral Pattern Analysis
The most sophisticated fraud detection doesn't rely on IP or device identity—it analyzes behavior:
- Micro-Behavior Analysis: How users move mice, scroll pages, click elements, and interact with content reveals whether they're human or bot. Humans show natural variation and purposeful movement. Bots show algorithmic precision and unnatural patterns.
- Engagement Depth Measurement: Genuine customers spend time examining content, reading information, and making informed decisions. Fraudsters land-and-click instantly or show impossibly fast page interactions.
- Conversion Path Analysis: Legitimate users follow logical conversion paths—reading about products before purchasing, viewing multiple pages before form submission. Fraud shows illogical patterns—immediate form fills, instant checkouts, no content engagement.
- Temporal Pattern Recognition: When do clicks occur? Legitimate traffic follows human patterns—business hours for B2B, evening/weekend for B2C. Bot traffic shows inhuman consistency or suspicious clustering during low-oversight hours.
- Geographic Coherence: Does the user's behavior make sense for their claimed location? Midnight clicks from Singapore when you sell Dallas-only plumbing services indicates fraud that IP-based geographic analysis catches.
ClickFortify's behavioral algorithms catch fraud that looks legitimate by IP and device but acts fraudulently through behavior patterns.
Layer 4: Machine Learning Pattern Recognition
Static rules catch known fraud patterns. Machine learning catches novel attacks:
- Continuous Model Training: Neural networks trained on billions of clicks continuously identify emerging fraud patterns without explicit programming. As fraudsters develop new techniques, machine learning adapts automatically.
- Anomaly Detection: Rather than looking for specific fraud signatures, machine learning identifies traffic that deviates from your normal customer patterns—catching sophisticated fraud that doesn't match any predefined rule.
- Cross-Campaign Intelligence: Fraud patterns detected on one campaign automatically inform protection on all campaigns. If a new bot network attacks Campaign A, machine learning immediately protects Campaigns B, C, and D from the same threat.
- Predictive Blocking: Advanced algorithms don't just detect fraud after it occurs—they predict likely fraud sources before they attack. Traffic showing multiple weak fraud signals (not enough to block individually) gets classified as high-risk and monitored closely.
- Adaptive Threshold Optimization: Machine learning continuously adjusts fraud detection thresholds based on your specific traffic patterns, industry norms, and seasonal variations—maintaining protection effectiveness as conditions change.
Layer 5: Real-Time Automated Enforcement
Detection without enforcement is documentation, not protection. ClickFortify's automated integration makes protection actually work:
- Sub-50ms Analysis Speed: Every click is analyzed in under 50 milliseconds using edge computing infrastructure. This enables real-time blocking decisions before ads are served or budget is consumed.
- Instant IP Exclusion: When fraud is detected, ClickFortify immediately adds that IP to your Google Ads exclusion list through direct API integration. No manual CSV uploads, no delays, no gaps in protection.
- Automated Device-Based Audiences: Fraudulent devices are automatically added to exclusion audiences in Google Ads. These audiences block the device across all campaigns regardless of IP changes.
- Cross-Campaign Propagation: Fraud detected on one campaign immediately protects all campaigns. The instant a malicious source is identified anywhere, it's blocked everywhere.
- Account-Level Protection: ClickFortify leverages Google's account-level IP exclusions to block fraud across ALL campaign types—Search, Display, Shopping, Performance Max, Demand Gen, Discovery, YouTube, and App campaigns.
- Smart Exclusion Management: While implementing blocking, ClickFortify manages the 500-IP limit intelligently—prioritizing highest-threat IPs, using range blocking to maximize coverage, and automatically rotating older exclusions to make room for new threats.
Layer 6: Intelligent Reporting and Fraud Visibility
You can't improve what you can't measure. ClickFortify provides transparency that manual IP blocking never achieves:
- Detailed Fraud Source Intelligence: See exactly which IPs, devices, geolocations, and ASNs are attacking your campaigns. This intelligence enables strategic response beyond simple blocking—adjusting targeting, refining audiences, and optimizing vulnerability.
- Saved Budget Quantification: Know precisely how much money fraud protection saves. ClickFortify calculates exact dollar amounts blocked, proving ROI through transparent reporting.
- Attack Pattern Recognition: Identify when fraud occurs, which campaigns are most vulnerable, and how attacks evolve over time. This intelligence transforms fraud protection from reactive defense to strategic advantage.
- Campaign-Specific Vulnerability Analysis: Which campaigns, ad groups, and keywords attract the most fraud? This reveals optimization opportunities—adjusting bids on clean traffic, reallocating budget from fraud-heavy campaigns to cleaner alternatives.
- Time-Series Trend Tracking: Monitor how fraud targeting your campaigns changes over weeks and months. Are attacks increasing or decreasing? Are fraudsters changing tactics? This longitudinal view enables proactive protection adjustments.
- Exportable Data: Complete fraud data exports for deeper analysis, stakeholder reporting, or integration with business intelligence systems. Your fraud intelligence becomes usable across your entire organization.
The Result: 85-95% Fraud Detection vs. 30% with IP Blocking Alone. Each protection layer catches fraud the others miss. Together, they create comprehensive defense.
Strategic IP Blocking: Best Practices for 2027
Whether using ClickFortify's automated protection or manual IP management, these strategic principles maximize effectiveness:
Principle #1: Prioritize Certainty Over Volume
With 500-IP limits, blocking strategy matters more than blocking volume:
- High-Priority Blocks: Data center IPs, known bot networks, confirmed competitor IPs, obvious click farms. These high-certainty fraud sources justify permanent blocking.
- Medium-Priority Blocks: Suspicious patterns (repeated clicks, impossible geography, abnormal engagement) warrant temporary 30-60 day blocking while monitoring for false positives.
- Low-Priority Holds: Uncertain situations where traffic might be legitimate shouldn't consume limited blocking capacity. Monitor rather than block until certainty increases.
The Strategic Error: Filling your 500-IP limit with low-certainty blocks wastes capacity that could protect against confirmed threats. Quality over quantity in IP exclusions.
Principle #2: Use Range Blocking for Scale
Individual IP blocking is inefficient. Range blocking multiplies coverage:
- Identify IP Ranges: When fraud comes from specific data centers or networks, research the full IP range those facilities use. Tools like WHOIS lookups and IP location databases reveal ASN and subnet information.
- Strategic Wildcards: Block
203.0.113.* instead of multiple individual IPs. One entry blocks 256 addresses instead of using entries for single addresses.
- ASN-Based Blocking: If an entire Autonomous System Number is fraudulent (common with click farm hosting providers), block all IP ranges within that ASN systematically.
- Coverage Multiplication: Strategic range blocking can expand your 500-IP limit to cover millions of potential fraud addresses. A single entry blocking a /16 subnet excludes 65,536 IP addresses.
Principle #3: Implement Time-Based Rotation
Static IP exclusion lists become stale and counterproductive:
- The Rotation Strategy: Review your IP exclusion list monthly. Remove blocks from 60-90+ days ago to make room for new threats. IPs blocked three months ago are likely reassigned to different users by now.
- Prioritized Retention: Keep high-certainty blocks (confirmed bots, data centers, repeat offenders) longer. Remove low-certainty blocks (single suspicious incident) faster.
- Seasonal Adjustments: Some fraud increases seasonally (holiday shopping, tax season for financial services). Rotate exclusions more aggressively during high-fraud periods to maximize current threat coverage.
- Automation Advantage: Manual rotation is tedious and frequently neglected. ClickFortify automates time-based management, blocking IPs for optimal periods then releasing them before legitimate customer impact occurs.
Principle #4: Combine IP Blocking with Other Exclusions
IP exclusions work best alongside complementary protections:
- Placement Exclusions: Block fraudulent websites and apps showing your display ads. Many IPs are difficult to block (residential proxies); blocking the fraudulent websites they visit is more effective.
- Audience Exclusions: Create exclusion audiences for fraudulent devices. Unlike IP blocks that fail when IPs change, audience exclusions persist based on device/user identity.
- Geographic Refinements: If fraud concentrates in specific regions with no legitimate customer base, use geographic exclusions alongside IP blocking for layered protection.
- Dayparting Strategy: If fraud occurs predominantly during specific hours, implement ad scheduling to reduce exposure during high-risk periods while maintaining presence during clean traffic hours.
Multi-Layer Defense: No single exclusion type is comprehensive. Combining IP + placement + audience + geographic exclusions creates defense-in-depth that sophisticated fraud must defeat multiple ways to succeed.
Principle #5: Monitor, Don't Just Block
Blocking without analysis wastes the intelligence IP exclusions provide:
- Pattern Analysis: Why are you blocking these IPs? If fraud comes from specific regions, that reveals targeting vulnerabilities. If it clusters around certain keywords, that suggests competitive attacks or placement quality issues.
- Source Intelligence: Where is fraud coming from—competitors, data centers, specific countries? This intelligence informs broader campaign strategy beyond just blocking.
- Volume Tracking: Is fraud increasing or decreasing? Are your blocking strategies working, or is fraud finding new ways around them? Trend monitoring reveals protection effectiveness.
- False Positive Review: Periodically audit blocked IPs. Did you accidentally block legitimate traffic? Are there patterns in what you're blocking that suggest over-aggressive filtering?
- Competitive Intelligence: Fraud patterns often correlate with competitor activity. Spikes during their campaign launches, attacks concentrated on their core keywords—this intelligence reveals competitive strategy.
Principle #6: Don't Rely on IP Blocking Alone
The most important principle: IP blocking is one tool in comprehensive fraud protection, not a complete solution:
- The Multi-Layer Requirement: Effective fraud protection requires IP blocking + device fingerprinting + behavioral analysis + machine learning + automated enforcement. Any single method leaves significant vulnerabilities.
- The False Security Problem: Manual IP blocking creates comfort without comprehensive protection. You've done something, so you feel protected—while 70% of fraud continues undetected.
- The Automation Necessity: Modern fraud operates at digital speed across millions of IP addresses. Manual blocking operates at human speed across 500 IPs. The scale mismatch makes automation non-optional for effective protection.
- The ClickFortify Approach: Rather than choosing between IP blocking and other methods, ClickFortify integrates all protection layers into automated, comprehensive defense that actually works against sophisticated fraud.
Common IP Blocking Mistakes (And How to Avoid Them)
Even advertisers who understand IP blocking make costly implementation errors:
Mistake #1: Blocking Your Own Traffic
The most embarrassing error is blocking your own company's IP address, making your ads invisible to all employees:
- The Problem: Your team regularly searches for your brand, products, or services. Your ads show in results. Someone clicks (often accidentally), costing you money.
- The Overcorrection: You block your office IP to prevent these internal clicks. Now employees legitimately researching competitors, market conditions, or ad performance can't see your ads at all—breaking competitive intelligence and campaign monitoring.
- The Right Approach: Block your office IP only from campaigns where employee viewing provides no value (recruitment ads, competitor targeting campaigns). Allow your IP for campaigns where employee monitoring is valuable. Or use incognito/private browsing for internal searches instead of blocking IPs.
Mistake #2: Blocking Customer VPNs and Privacy Tools
Privacy-conscious users increasingly employ VPNs, privacy browsers, and tracking protection:
- The Problem: These privacy tools often use shared IP addresses. Blocking a VPN provider's IP might exclude thousands of potential customers valuing privacy.
- The Bad Logic: "VPN traffic doesn't convert as well as regular traffic, so I'll block VPN IPs." This confuses correlation with causation—VPN users might have different intent, but blocking them excludes the legitimate customers among them.
- The Right Approach: Analyze VPN traffic conversion rates versus cost. If VPN traffic converts at 50% of regular traffic but costs the same, reduce bids rather than blocking entirely. Only block specific VPN IPs showing clear fraud patterns (repeated clicks, zero engagement), not VPNs broadly.
Mistake #3: Never Reviewing or Updating Exclusions
Static IP exclusion lists decay into ineffectiveness:
- The Problem: You block 500 IPs over six months, then stop managing the list because it's "full." Many of those IPs are no longer fraudulent (reassigned to legitimate users), while new fraud sources attack unblocked.
- The Neglect: IP exclusion lists require active management. Neglected lists fill with stale blocks while current threats go unaddressed.
- The Right Approach: Monthly audits of IP exclusion lists. Remove blocks older than 60-90 days to make room for current threats. Document why each IP is blocked to aid future review decisions. Or use ClickFortify's automated management eliminating manual review requirements.
Mistake #4: Blocking Individual IPs Instead of Ranges
Inefficient blocking wastes your 500-IP capacity:
- The Problem: You identify fraud from
203.0.113.15, 203.0.113.27, and 203.0.113.89—all from the same data center. You block each individually, consuming three exclusion slots.
- The Efficiency Loss: These IPs are likely from a larger pool the data center rotates through. Blocking three IPs while hundreds remain available wastes protection capacity.
- The Right Approach: Block
203.0.113.* with one wildcard entry, excluding 256 addresses. Research ASN and subnet information to identify full IP ranges associated with fraud sources, then block entire ranges strategically.
