Today, I was checking backlinks of my website which is currently being advertised on adwords I was quite amazed when I saw backlinks on few websites where I didn't put my site link. I checked all sites link but I couldn't my link after that I checked cached copy of all sites, I found my website link on adsense ads. It appears Google is now crawling adsense ads and considering them as a backlink. It is a temporary backlink but it gets you on Google search page..
