If I have say 5000 impressions of my ads from Google, Is that considered 5000 back links linking my site? If so why not have a low CPC price with key words where they prob never get clicked just to have the back links? Sorry if its stupid question, I'm real new tho this stuff, but it is links to my site right?
No, because the ads are served with JavaScript. Second, if I recall correctly, an impression is the number of times the ad has been displayed.
I get sites listed all the time in Google for my sites. I dont think they're links, but are crawled and listed in Google. Check out this Google link: http://www.google.com/search?hl=en&suggon=0&safe=off&q=www.photoheap.net&btnG=Search (Watch for the phrase: "Fast Servers! Free non-adult image hosting." they are mostly Adwords listings that were crawled somewhere... They list the original site that displayed my ads...
