I am assuming that the use of Google Adwords / Adsense has no affect on links to your site - incoming and outgoing Adsense The code is javascript and Google will not spider it(??) when it visits your site and see that there is a link from Google and out going link to another site. Adwords Apart from the fact that Google deny that use of Adwords affects a site ranking, I assume that the link from Google (where your advert displays) and from other sites displaying your "Adword" does not contribute to link popularity?
AdSense Support says: How does participation in this program affect my site's position in the Google search results? Participating in Google AdSense does not affect your site's rank in Google search results and will not affect the search results we deliver. Google believes strongly in freedom of expression and therefore offers broad access to content across the web. Our search results are unbiased by our relationships with paying advertisers and publishers. We will continue to show search results according to our PageRank technology. Adding the Google AdSense ad code or AdSense for search code to your site will not queue your pages for crawling by our main index bots. While our bot (starting with 'Mediapartners-Google') does crawl content pages for the purpose of targeting ads, this crawl is not associated with our main index crawl.
