Use Blekko To Find Your Competitors Sites Via AdSense Pub ID

Dec 30, 2010 • 8:59 am | comments (11) by twitter Google+ | Filed Under Other Search Engines

Most Webmasters and Google AdSense publishers know that the AdSense code you place on your site includes your unique AdSense publisher ID. So if you ever wanted to track down all the places and sites that AdSense ID is used on the web, technically you can just search for the unique ID on various web sites.

Well, Blekko has made it easier.

If you type in any site, such as this or even [TechCrunch] into Blekko, you will see a link for "adsense" under the title of the page. Clicking on that will take you to a search for [/adsense=6181816114362650] which is the AdSense ID used on TechCrunch. It then lists out all the sites on the web using that ID.

Now, keep in mind, a couple things:

(1) Scrapers will often copy your AdSense code and AdSense ID and include it on their sites.

(2) Your competitors may have additional AdSense accounts, all with unique IDs.

This is a great way to do a little competitive intelligence . . . thanks for the tip!

FYI, it also works with Google Analytics and other metrics suites. You've got to dig through the code and remove parts of it. OpenX ad server works too. So do some other popular widgets. Using those techniques one can find several "interesting" sites run by many mainstream SEO people or all of the spam pages that Mahalo has created. Sites like this one ( ) where they created tons of content that just links to Mahalo.

Not all sites have the adsense tab although they definitely use adsense. I checked a client's competitors and they didn't have that option. Why's that?

The data is not very accurate in some categories (such as duplicate content) but seems to be pretty reasonable in other categories. People should keep in mind that Blekko is NOT a reliable source of information for what Google or Bing know about a site OR for how Google or Bing evaluate a site.

Hope this information will always be used for healthy and clean intentions and not doing anything wrong to those who are earning money doing extraneous labor and efforts.

You can also use Reverse Get to search by AdSense / Analytics ID:

This no longer appears to work.

Much easier to use: Just enter domain name and see all sites with the same IDs

I don't think the method works now... any suggestion...

Thanks for the information, unfortunately as others point out in previous comments the blekko method does not work anymore.
