The idea of whether or not Adsense publishers have a Google advantage is changing from a definitive no to a maybe for some people. My answer is still a no, but that’s not to say that part of the logic for a yes answer is necessarily wrong.
From Industry News, Marketing Trends: Google’s Matt Cutts Confirms AdSense Bot to BigDaddy Connection:
Now to sort out the issue of whether or not this indicates a SERPs advantage for AdSense publishers…I stated in a previous post, without verifying it, that “AdSense publishers’ content is indexed and cached more frequently.” Jon Revill’s digging into that now with some internal data.
If it can be shown that AdSense publishers’ pages ARE updated more frequently than non-AdSense sites then I think we can build the case that Google’s favoring its business partners over its non-business partners in its SERPs.
For me, though, a question still remains, several questions in fact.
First, does the fact that your site is being spidered more frequently (to obtain the context of your page to display ads) by the Googlebot dedicated to Adsense, mean that your page is going to be included in Google faster and/or favored over other pages?
Second, if so, then why aren’t more Adsense publishers making more money? Their pages would be at the top of the rankings, and they’d get more searches even if their pages weren’t as good, under this theory.
Until someone can answer both of those questions to my satisfaction, with some kind of concrete proof that it isn’t the quality of their pages, but the presence of AdSense, that got their pages ranked (not spidered- but indexed and ranked well), I still don’t think having AdWords on your pages is enough of an advantage for that to be reason in and of itself to join the Adsense program.
I agree that it’s possible that the different Googlebots share data, because that would be efficient. I’ll concede that perhaps having AdWords gets you spidered faster than not having them.
But even if you can get spidered overnight by having Google ads on your pages, there are plenty of other ways to get spidered within 24 hours – in fact, I’d consider that slow. At certain times of day, with your link in certain places, you can get spidered in 6 hours – even in 15 minutes if you’re a blogger.
My second issue is that just because you’re spidered doesn’t mean you’re going to get indexed, by any means. Even if you get indexed, it doesn’t mean your rankings are going to increase if the content on your page and the document relationship between your keywords, link popularity, and your site’s individual documents are not a match.
You have the same chance of being indexed no matter what method you use for your site to get picked up, if the pages are identical. And to get ranked better depends on how you are linked more than whether the spidering was initiated by the fact you submitted, linked from a web document or display AdWords on your page.
Google??Adsense?????
