Google Ads Placement Exclusion List for Google Display Network (Updated 2025)

This article was updated 04/21/2025.

Excluding placements in the Google Display Network (GDN) isn’t just a hygiene tactic—it’s a strategic lever for improving ROI and campaign efficiency.

GDN Placement Exclusions

Google’s AI-driven placement algorithms are continuously improving. Right now, though, they still lack the nuance to fully understand brand suitability or the nuanced goals of a specific campaign. That’s why the proactive exclusion strategies we detail below are important.

Start by considering the context in which your ads appear. Certain websites or app categories—such as mobile games with accidental clicks or sensationalist news sites—may technically deliver impressions, but they rarely contribute to meaningful engagement.

Looking at your placement reports clues you into patterns that you can take action on: high impressions with low conversions, unusual CTR spikes, or bounce-heavy traffic sources. These indicators often point to placements worth excluding.

Audience intent is crucial. Even on high-traffic, reputable sites, your ad might not belong if the user’s mindset doesn’t match your offer. For example, placing a B2B SaaS ad on a recipe blog won’t align with user expectations, regardless of the domain quality.

Brands with international campaigns should also consider cultural and legal sensitivities. Some domains or categories might be legally acceptable in one country but damaging in another.

GDN exclusions aren’t set-and-forget. They’re part of a feedback loop. Make it routine—monthly at minimum—to review your placements and performance metrics. Couple this with developing your own dynamic exclusion list, informed by your brand’s specific needs, vertical trends, and prior campaign data.

Background on the Google Display Network

With more than a million websites across the globe, the sheer size of the Google Display Network is one of the main reasons why display and retargeting campaigns are such strong marketing tools. Spanning myriad topics and interests, reaching a target audience based on what matters to them has never been easier.

A high-performing campaign leverages the Google Display Network by serving highly targeted ads to users somewhere across the mammoth network of websites and publishers. Odds are, if a user is seeing a display or retargeting ad, they are seeing it on a website in the GDN.

However, there are thousands of websites with which brands do not want to be associated. This is why it’s a good idea for advertisers to consider blocking or excluding certain websites for placements of their ads on the Google Display Network.

Why Exclude Some Websites on the GDN?

It may seem counterintuitive that blocking placements on some websites would lead to better campaign performance, but there are instances where blocking placements can be extremely beneficial. There are two main reasons why advertisers should exclude websites on the Google Display Network.

1. Spammy, Inappropriate, or Unrelated Websites

Considering how large the Internet is, it’s pretty clear that no matter what a person is interested in, there is likely a large community and hundreds of websites dedicated to that interest. This covers a gamut of topics from the very wholesome to the very “adult.”

Advertisers probably don’t have the luxury to consider and evaluate every single website on the GDN. That would take hours. But serving ads on a spammy, inappropriate website (or one that’s just not very related to your brand) can have unintended consequences. For example, say a butcher shop sets up a display campaign, and several of its ads are placed on websites whose audiences are passionate about the vegan lifestyle and animal rights. Not a great match.

2. Saving Money on the GDN

Besides avoiding placements because of a mismatch for relevancy or inappropriate misrepresentations of a brand, the big reason for blocking placements on the display network is to save money. When targeting is dialed in and a retargeting campaign is set up correctly, advertisers can reduce costs by eliminating irrelevant websites.

Say that a SaaS software company runs a display campaign but they don’t exclude a whole ton of websites geared towards teenaged and college-aged gamers. These placements eat away at the ad budget, and they don’t contribute meaningful conversions to the campaign.

By eliminating a whole slew of such websites, advertisers leveraging the GDN can ultimately get more out of their campaigns with lower costs if they refine where ads are being placed.

How to Block Placements on the GDN

Seasoned digital marketers may know about website exclusions, but they can be easily overlooked by less-experienced users of Google Ads.

At the most basic level, placements can be excluded by opening your campaign in Google Ads and clicking on the “Placements” tab. From there, hover the mouse over the top navigation and click on the “Exclusions” tab.

Once in this new area, exclusions can either be selected by website, YouTube channel and video, app, or by entire app categories.

It’s important to keep in mind that Google Ads’ exclusion tools don’t cover every website worth excluding from a campaign, and there are thousands it will miss.

Using an exclusion list can be a mighty weapon for any digital marketer working inside the Google Display Network — one you’ll want to come back to over and over again.

The Definitive Website Exclusion List (Free Resource!)

For years, Google Ads professionals have either had to resort to creating their own exclusion lists or borrowing lists of URLs from fellow marketers.

The team at Direct Online Marketing has created the exclusion list to end all exclusion lists.

This list is the culmination of our two decades as an agency running campaigns for clients in Google Ads. (To supplement our internal list, we also took every list of website exclusions we could find online and compiled it all in the above Google Sheet.)

At a stunning 70,000+ website URLs, this list is quite comprehensive as it covers such categories as dating, mobile, gaming, quizzes, sports, and more. And hey, it’s free!

Because this list can be found as a shareable Google Sheet, we encourage you to share this with anyone who would find it useful.

Notes About High-Cost, Low-Performing Categories

If you’ve taken a look at our list, you’ve probably noticed how we broke out several website categories.

High-Cost, Low-Performing – One of our categories addresses a large number of high-quality and reputable websites and publishers (such as The New York Times, CNN, etc.). We’d generally recommend excluding or considering blocking placements on some of these sites for direct advertisers. The placements may make sense if you’re using GDN just for brand awareness and reach. Because exclusions can be a good method of keeping ad costs down, blocking placements on high-quality websites can help stretch budgets a lot farther.

Key Takeaways About Google Ads Placement Exclusions

• Excluding placements on spammy, inappropriate, or unrelated websites helps maintain brand integrity.
• Advertisers can exclude placements directly in Google Ads so that ads reach their intended audience.
• Blocking select websites can improve ROI by reducing wasted spend on placements that don’t convert.
• Direct Online Marketing offers a comprehensive list of over 70,000 website URLs for exclusion.
