I read here that the score for the gogle ads is 7/10,9/10 etc? what is it? and How do you find the same ? Thanks for the reply.
This has nothing to do with Adsense but Adwords instead. If you're an Adwords advertiser (you place your ads on Google's search and on Adsense publishers' sites and pay for it) then you get assigned what Google calles Quality Scores - this basically determines how well your ad gets treated among competitors and the score depends on several factors, including the CTR and the relevacy of your site.
