Google Ads Search Partners Conversion Rates

Below is a small Call Ads campaign (formerly called “Call-Only” Campaigns) where search partners were accidentally left enabled for a few days. After segmenting the campaign by “Networks,” the impact was immediately visible.

Google Ads Search Partners List

So who are these infamously secret “Search Partners”? Some are already known — Google Maps, YouTube, and Gmail. But the full list has always been hidden.

A quick search turns up articles claiming to list search partners, but most are just primers that don’t provide an actual list. However, one useful example is The Guardian Newspaper. Clicking their search button reveals “Powered by Google Custom Search” — now called the Programmable Search Engine, a free Google product any site can embed to add a search box, with ads shown in the results.^{[3]Programmable Search Engine overviewdevelopers.google.com}

How to Find the Complete List

A simple right-click and “Inspect” on Google Chrome on the search box reveals the source code containing Google Search Console (GSC) identifiers:

Take any of those GSC identifiers and plug them into a source-code search engine such as PublicWWW.com (make sure to add “quotes” around the word for phrase-match). PublicWWW indexes the HTML, JavaScript, and CSS of hundreds of millions of pages, so you can find every site running a specific code snippet.^{[4]PublicWWW source code search enginepublicwww.com} The result: a list of all Google Search Partner sites, at least the ones that don’t block crawlers.

Using c-sharpcorner.com as an example Google Search Partner, here’s how search ads appear when typing “Home Insurance” on a programming website:

Google Display Network Partners List

The Google Display Network (GDN) is extremely hard to convert. Success typically comes only from strictly remarketing campaigns. For reference, GDN ads look like typical banner ads served across partner websites.

For the Google Display Network, search for the following code on PublicWWW:

• adsbygoogle

This results in more than a million Google Display Network Partners:

Microsoft Ads Syndicated Search Partners List

Microsoft Ads is slow to implement features compared to Google Ads (such as proper call-only ads and call tracking), and their network is filled with bot and fraud traffic clicking on ads.

Their major search networks include legitimate engines. Microsoft itself lists Yahoo, AOL, DuckDuckGo, and Ecosia as the named search partners where its ads appear alongside Bing:^{[5]Microsoft Search ads & partner sitesabout.ads.microsoft.com}

• Yahoo.com
• DuckDuckGo.com
• Ecosia.com

But they also have a bunch of fraudulent websites using their search engine:

• searcheshut.com
• financerepublic.com
• performancelab.net
• kol.com (the following three all look identical)
• leadlocal.com
• enow.com
• bingappnetwork.com

You can discover Microsoft Ads Syndicated Search Partners by searching PublicWWW for:

• “Results by Microsoft”
• “Powered by Bing”

Many of these fraudulent clicks also extend into Microsoft Ads Syndicated Partners Shopping Campaigns:

Microsoft Ads Audience Network

On PublicWWW, you can search for Microsoft Ads Audience websites using “go.microsoft.com/fwlink/?LinkID=286759“:

Call Ads Search Partners Conversions Part 2

It’s not all bad news. With respect to Call Ads on search partners, enabling the “Phone Calls” column reveals how many clicks actually converted into calls. Here are the results for Google Search vs. Google Search Network:

Search Partners had a 0% phone-through-rate (PTR). However, when running this on another campaign, conversions did appear — meaning the PTR metric for search partners simply doesn’t work reliably.

Conclusion

The recommendation remains the same: disable search partners unless you have a strong reason to keep them enabled.

• Google Ads Search Partners – No transparency, no segmentation, and you’re fighting an uphill battle for conversion optimization. Google has also rolled back the ability to opt out in some campaign types (Performance Max), replacing it with placement reporting instead.^{[2]Google removes Search Partner opt-outsearchengineland.com} This territory is only for advanced marketers who are already profitable.
• Microsoft Ads Syndicated Partners – Mostly a joke, with only a few good search engines (Ecosia, DuckDuckGo). To use these networks, you need to pre-build a website exclusion list to filter out the garbage.
• Google Display Network – Over a million partner sites, best used exclusively for remarketing.
• Pay Per Call on Search Partners – Hit and miss. There’s potential, but conversion optimization is nearly impossible without proper segmentation tools.
