Google's help docs describe several exclusion controls. Negative keywords help exclude search terms and focus spend on relevant searches. Placement exclusions help prevent ads from showing on specific websites, videos, channels, and apps. Google also notes that IP exclusion can prevent ads from showing to a particular IP address. See Google's docs on negative keywords, placement exclusion lists, specific webpage and video exclusions, and IP addresses.
This guide explains which exclusion list to use, when to use it, and how to avoid overblocking real prospects.
Exclusion List Types
| Exclusion type | Best for | Use carefully because |
|---|---|---|
| Negative keywords | Irrelevant searches and low-intent terms | They can block useful queries if too broad |
| Placement exclusions | Weak websites, apps, videos, and channels | One poor placement does not prove the whole channel is bad |
| Location exclusions | Markets you do not serve or locations with repeated waste | Location data is not perfect and buyers can travel |
| IP exclusions | Specific repeated sources with evidence | Shared and dynamic IPs can include real users |
| Content suitability exclusions | Brand safety and content categories | Too much restriction can reduce useful reach |
| Audience exclusions | Existing customers, poor-fit lists, or irrelevant segments | Bad list hygiene can remove qualified users |
The best exclusion setup usually combines several small, precise controls instead of one broad block.
1. Negative Keyword Lists
Negative keywords are the first exclusion layer for Search and Shopping campaigns. They stop ads from showing on searches that include terms you do not want.
Useful shared lists include:
- Career intent: jobs, salary, resume, hiring
- Education intent: course, class, tutorial, definition
- Free-only terms when you sell a paid offer
- Support terms: login, contact, customer service
- Low-fit locations outside your market
- Queries that spend repeatedly without qualified leads
For Performance Max, Google also supports negative keywords for Search and Shopping inventory. Use them for clearly irrelevant or brand-safety terms rather than trying to micromanage every query.
2. Placement Exclusion Lists
Placement exclusions help with Display, video, Demand Gen, and other broad inventory where weak websites, apps, videos, or channels may consume budget.
Review placements for:
- spend with no qualified outcomes
- clicks with no engaged sessions
- repeated fake or rejected leads
- inventory that does not fit the brand
- app or video placements that create accidental clicks
- placements that spike after campaign expansion
For manager accounts, Google supports placement exclusion lists that can be applied across selected client accounts. That is useful for agencies managing repeated poor placements across many accounts.
3. Location Exclusions
Location exclusions are useful when you do not sell in a region or when a location repeatedly spends without sales value.
Before excluding a location, check:
- campaign location settings
- whether the location is truly outside service coverage
- cost per qualified lead by location
- sales acceptance by location
- whether the spike is temporary or recurring
Avoid blocking a whole country, state, or city because of one suspicious day. Start with bid or budget segmentation when the evidence is mixed.
4. IP Exclusions
IP exclusions are useful for specific repeated sources, but they are not a complete fraud strategy.
Google's IP address documentation notes that internet service providers can assign the same IP address to many computers. That matters because blocking one IP can sometimes block more than one user.
Use IP exclusions when you have evidence such as:
- Repeated clicks from the same source with no qualified behavior
- Known internal, agency, or vendor IPs that should not see ads
- Specific networks producing repeated fake leads
- Short sessions from expensive keywords tied to the same source
- Clear click-level evidence from traffic monitoring
Do not rely on IP exclusions alone. Modern suspicious traffic can rotate through devices, networks, mobile carriers, VPNs, and proxies.
5. Content and Brand-Safety Exclusions
Content suitability controls help reduce placements near content that does not fit your brand. These are different from performance exclusions.
Use them when:
- the content environment is inappropriate for the brand
- regulated or sensitive categories need tighter control
- video or display campaigns are expanding into unsuitable inventory
- stakeholders require documented brand-safety rules
Performance review and brand-safety review should both happen, but they answer different questions.
6. A Safe Exclusion Workflow
Use a repeatable process so exclusions improve performance instead of randomly shrinking reach.
| Step | What to do | Why it matters |
|---|---|---|
| Find | Review search terms, placements, locations, devices, invalid clicks, and CRM outcomes | Exclusions should come from evidence |
| Classify | Decide whether the issue is intent, inventory, geography, IP, or lead quality | The fix depends on the source of waste |
| Apply | Add the narrowest exclusion that matches the evidence | Prevents overblocking |
| Document | Record the reason and date for each important exclusion | Makes later review possible |
| Measure | Check qualified leads, cost, CTR, CPC, and conversion rate after the change | Confirms whether the exclusion helped |
| Refresh | Remove stale or low-confidence exclusions during monthly review | Keeps lists from becoming too restrictive |
7. What Not To Exclude Too Quickly
Be careful with:
- shared office buildings
- mobile carrier IPs
- large cities
- entire devices
- entire campaign types
- all broad match traffic
- all partner or broad inventory
Sometimes the right move is segmentation, lower bids, or better conversion tracking rather than a hard exclusion.
8. When Automation Helps
Manual exclusion review works when spend is small and patterns are simple. It becomes unreliable when:
- suspicious sources rotate
- CPC is high
- broad campaign types spend quickly
- agencies manage many accounts
- lead quality is slow to confirm
- repeated waste appears outside weekly reporting
ClickFortify helps teams monitor paid-click behavior, identify repeat suspicious sources, and manage evidence-backed exclusions without guessing. Start with Google Ads click fraud protection software when exclusion management needs to happen faster than manual review.
Final Takeaway
Google Ads exclusion lists are one of the most practical ways to improve traffic quality. Use negative keywords for bad searches, placement exclusions for weak inventory, location exclusions for bad markets, and IP exclusions for specific repeat sources.
The strongest rule is simple: exclude based on evidence, review regularly, and protect real prospects from being blocked by overly broad rules.

Frequently Asked Questions
What are Google Ads exclusion lists?
Google Ads exclusion lists are controls that stop ads from showing for selected keywords, placements, websites, apps, videos, locations, or IP addresses. They help reduce irrelevant impressions, weak clicks, and traffic that does not match your business.
Which exclusion list should I use first?
Start with negative keywords for irrelevant searches, placement exclusions for weak Display or video inventory, and location exclusions for markets you do not serve. Use IP exclusions only when you have specific evidence about repeated suspicious sources.
Do IP exclusions stop click fraud?
IP exclusions can stop repeat traffic from known sources, but they are not complete fraud protection. Dynamic IPs, shared mobile networks, VPNs, and rotating proxies can make IP-only blocking unreliable.
Can exclusions hurt performance?
Yes. Exclusions can block real prospects if they are too broad. Add exclusions from evidence, review performance after changes, and avoid blocking whole devices, locations, or audiences because of one bad pattern.
How often should I review exclusion lists?
Review search-term and placement exclusions weekly for active campaigns. Review IP, location, and account-level exclusions monthly so stale rules do not block useful traffic.
