Google Ads Exclusion Lists: IPs, Placements, Keywords

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

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:

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:

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.

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.
