hello friends, i want know what use of google ads if I add our site this ads and what effect of our site rankings and PR.......
You'll get no improvement in SERPs or PR from using Google Ads. If you place the ads in a too btrusive manner you may put your visitors off and reduce the effectiveness of the site.
you means google adds no profit no loss then i see mostly site add our site google adds why added google adds and what use of others websites..plz tell me
People put adsense on their sites to make a bit of money out of the advertising revenue. It's got nothing to do with serps, rankings or seo.
i would love to know if there were two equal sites ranking for keyword '000900007nsnsnsnsns' (ie only two sites on the net targetting that keyword) and both were blogger blogs, would the one with adsense rank higher everythign else being equal? adsense makes google money, so i bet it would! however, in the real world, i doubt it makes any difference one way or the other.
