Frequently Asked Questions
How do I find all websites that use the same AdSense publisher ID?
Enter a Google AdSense publisher ID in the format pub-XXXXXXXXXXXXXXXX into the search box and click Search. The tool queries a database of crawled website source code, returning a list of domains that contain that same publisher code. Results include the domain name, page title, and when it was last indexed.
What is a reverse AdSense lookup used for?
Common use cases include discovering affiliate or sister sites owned by the same publisher, competitive research to identify all web properties a publisher operates, ad fraud investigation (identifying site networks sharing a single pub code), and academic or SEO research mapping website ownership relationships. The same pub code across multiple domains is a common signal that sites share the same owner.
How does the tool know which sites share an AdSense publisher code?
The database is built by crawling publicly accessible web pages and extracting AdSense publisher codes from JavaScript snippet attributes, meta tags, and ad unit markup. The coverage depends on how many pages have been indexed — it is not a complete record of every page on the internet, so results represent a sample of publicly crawled data.
Does this tool require me to have an AdSense account to use it?
No. The lookup requires only a valid pub-code string, which is embedded in the publicly visible HTML source of any page running AdSense ads. You can retrieve a pub code by viewing the page source of any AdSense-enabled site and searching for 'pub-'. No authentication or Google account access is needed.
What is a limitation of reverse AdSense lookups?
Publisher codes appearing in search results are only those captured during crawls. Sites with rel=noindex, robots.txt disallowing crawlers, JavaScript-only ad loading, or low crawl frequency may not appear even if they share the publisher code. Results should be treated as a representative sample rather than a definitive complete list of all sites for a given pub code.
