Adsense Ads Effecting PR and SERPs

[antonaf]

This is a theory. I'm not sure if this has been discussed or revealed, but I did not find any topic about it. Hope I'm not reiterating.

It would be interesting to know if Google internally uses Adsense ads to rank sites in the SERPs. Since Adsense ads are perfectly targeted it would make since that Google will crawl the Adsense ads on a publisher site and then match its results with sites of the same caliber and financial bracket then rank up or down from that.

Meaning, if SiteA has 1,000,000 Adsense ad impressions on the network about widget and SiteB has 700,000 Adsense ad impressions on the same network about the same widget then SiteA becomes a authority over SiteB for the targeted keyword(s).

My understanding is that Google does not spider Adsense ads. Adsense ads does not create Google backlinks or effect PR.

If I recall right, Google says there is no relationship between Adsense and how a site ranks in the serps.

I haven't seen any credible reason not to believe that.

Firstly, because adsense is done in javascript it should not be spidered - the bots dont read javascript (or not complex js like this - there are no urls sitting there plainly in the script text)
Secondly, in theory, there should be no connection between the adsense system and the general search results system. This is like the old system in newspapers where the people handling the advertising weren't connected to the journos writing the stories.
*However* bear in mind that every now and then there are/were accusations of intermingling and, basically, corruption on the various newspapers.
Similarly, while we like to believe that they are separate at Google, and Google has certainly stated that they are separate, but we can only take this on good faith and hope that it is true.
It makes sense for them to keep it separate, as they would surely get caught at some point and it would definitely be Evil, but the devil on my right shoulder says that I hope they are doing it, because it would increase my income :( Bad devil...

However,

There are many sites with data feeds to google search.

These feeds grab the ads from google search and display them on their pages. I'm working with G support now to determine if these ads are 'live' and are costing me money.

These grabbed ads are HTML, not java. And they show up in the search results for your domain name if you are an adwords advertiser.

Also, many sites that use this technique are doing multiple 302 redirects during the click from the ad to your site.

So, the result is that there is several points of opportunity for this tactic/method to influence your sites position.

Amazon and ostg.pricegrabber both use this method. pricegrabber show 500,000 such links in the search results. I haven't seen amazon's links show up in my inurl: command but pricegrabber shows up for about 50 links.

Ohhh, about.com uses it too and results show in the inurl:
