Google Ads Placement Exclusions: Limits, Scope and Where They Do Not Work

Placement exclusions are the one lever that still gives an ecommerce advertiser direct control over where automated campaigns serve. They are also the lever most accounts apply at the wrong level, which is why the same junk placements keep reappearing in reports.

This guide covers the numeric limits, which campaign types account-level exclusions actually reach, the Search Partner rule that breaks subdomain exclusions, and the places where exclusion simply is not available.

Quick Summary

Placement exclusions stop your ads appearing on specific sites, apps, YouTube channels and videos. Applied at account level they cover every campaign in the account including Performance Max, and they take precedence over campaign and ad group placement settings.

• Account level beats campaign level. Google states account-level exclusions override campaign and ad group settings, which is why scattered campaign-level lists keep losing.
• The ceiling is 65,000 per account, with a maximum of 20,000 entered in one go.
• Manager accounts get more room. Up to 3 exclusion lists, each holding up to 250,000 exclusions, inherited by linked child accounts.
• Search Partner coverage arrived in March 2024 for exclusions added at account or manager level.
• Subdomain exclusions do not work on Search Partners. Only the full domain is honoured there.
• Changes take about 12 hours to take effect, so judging a fix the same afternoon tells you nothing.

The numbers that govern how much you can actually exclude.

What Are Placement Exclusions?

A placement exclusion tells Google Ads not to show your ads on a specific placement, meaning a website, a mobile app, a YouTube channel or an individual video. They apply across the Display Network, YouTube and, under the conditions described below, the Search Partner Network.

The important property is precedence. Google states that account-level exclusions override campaign and ad group level settings, so an exclusion added at the top of the account cannot be undone by a looser setting further down.

That makes the account level the right default home for anything you never want to appear on, and the campaign level appropriate only for exclusions that genuinely apply to one campaign and not the rest.

Which Campaign Types Do Account Level Exclusions Reach?

Every campaign in the account, including Performance Max. That is the single most useful fact here, because Performance Max offers very little placement control inside the campaign itself.

The Search Partner change has a narrower list. Since March 2024, placement exclusions added at account or manager account level also apply to Search Partner Network websites, and Google names the affected campaign types as Performance Max, App, Search, Shopping and Smart campaigns.

• Performance Max picks up account-level exclusions even though in-campaign placement control is limited.
• Display and Video have always respected them.
• Search, Shopping and App gain Search Partner coverage through the same lists.
• Manager level lists are inherited by every linked child account, which is how an agency applies one brand safety standard across a roster.

The Content section only appears in the interface when the account actually has Video, Display, Demand Gen, Search, Performance Max or App campaigns, so a Shopping-only account may not see it at all until another campaign type exists.

What Are the Limits?

Three numbers matter. You can enter a maximum of 20,000 placement exclusions at one time, hold a maximum of 65,000 exclusions per account, and create up to 3 placement exclusion lists at manager level with up to 250,000 exclusions each.

The gap between the account ceiling and the manager list ceiling is the part worth planning around. An agency maintaining a large blocklist cannot push all of it into one account, but can hold it at manager level and inherit it down.

New exclusions typically take effect within 12 hours, and the change can be verified in Change history. That delay is the reason a same-day check after a bulk upload is not evidence of anything.

How Does the Search Partner Rule Change Things?

It extends coverage and introduces one real limitation. Account and manager level exclusions now reach Search Partner websites, but Google states plainly that placement exclusions for subdomains, subsites and subpages do not work on the Search Partner Network.

The practical effect is that a precise exclusion silently becomes a partial one.

Table: how exclusion specificity behaves across networks.

Two consequences follow. If a subdomain is the problem and Search Partners are the surface, the only effective exclusion is the whole domain, which is a bigger decision than it first appears. And every country domain needs its own entry, so excluding example.com does nothing for example.co.uk.

Where Can You Not Exclude?

Two gaps are documented, and both catch people mid-investigation.

1. Google domains cannot be added directly. URLs on Google domains, mail.google.com for instance, cannot be entered as placement exclusions.
2. The whole of youtube.com cannot be excluded as a campaign-level placement, which Google calls out specifically for Performance Max.

For YouTube the documented alternatives are to exclude specific channels or videos at account level, to use content suitability settings, or to withhold video assets from the campaign to reduce YouTube serving. That last one is a trade, not a setting, because removing video assets changes what the campaign can do elsewhere.

How Do You Add Exclusions at Account Level?

Five steps, and the entry format matters more than the navigation.

1. Open the Tools tab.
2. Select Content suitability.
3. Select Advanced settings.
4. Under Excluded placements, enter the URL or search for content, written without the www. prefix. For a large list, choose Enter multiple placements and paste it in.
5. Save, then confirm the entry in Change history.

The www. detail is the one that quietly fails. A list exported from an analytics tool usually carries the prefix, and pasting it in unedited produces entries that do not match.

What Else Can Be Excluded Besides Placements?

Placement exclusions are one of several controls, and reaching for the wrong one is common. At campaign level for Display, the exclusion types are topics, placements and keywords. At account level, suitability settings cover websites, videos, channels and mobile apps.

• Excluded content at account level covers sensitive content categories.
• Excluded types and labels at account level covers content types and digital content labels.
• Topics exclude subject areas rather than specific sites.
• Keywords exclude contextual matches, which is a different mechanism from the negative keywords used in Search, covered in Google Ads negative keywords.

These combine. Google states you can use multiple exclusion types together, and ads will not match any of the selected excluded content in the ad group.

How Should an Ecommerce Account Use Them?

Start at the top and keep the list small enough to maintain. A blocklist of 60,000 entries that nobody reviews is worse than a list of 200 that reflects what you actually saw in reports.

1. Put the permanent list at account or manager level, because that is the only level that cannot be overridden.
2. Build from your own placement reports, not from a purchased list, since relevance differs by catalog.
3. Exclude whole domains when Search Partners matter, given subdomain exclusions do not apply there.
4. Add each country domain separately rather than assuming one entry covers the brand.
5. Review on a cadence rather than continuously, and remember the 12-hour delay before judging anything.

The honest position is that this is housekeeping rather than optimisation. It protects where spend lands, which matters, but it does not improve what happens after the click. That sits with the structure and bidding work covered in Google Shopping campaign priority and Performance Max for ecommerce.

When Are Placement Exclusions the Wrong Fix?

When the problem is the offer, the audience or the landing page rather than the location. Excluding placements narrows where you appear, and narrowing reach does not make a weak campaign strong.

• Poor conversion rate across all placements is a landing page or offer problem, not a placement one.
• One expensive placement that converts should be bid down or left alone, not excluded.
• Broad underperformance in Performance Max is usually an asset, feed or target problem before it is a placement problem.
• Brand safety concerns are better served by content suitability settings and labels, which exclude categories rather than naming sites one at a time.

There is also a scale limit worth saying out loud. The open web is larger than any blocklist, so exclusion is a filter rather than a wall, and an account that relies on it alone will always be one step behind.

Why Ecommerce Brands Choose Seller Splash

Exclusions live at the level that wins. Account and manager level, because Google's own documentation says those override everything beneath them. Campaign-level lists get consolidated rather than extended.

Lists are built from your reports, not bought. What wastes money on one catalog is fine on another, so we work from placement data in the account rather than a generic blocklist.

Housekeeping is named as housekeeping. Exclusions protect where spend lands. They do not fix an offer, and we do not present them as if they do.
