I am still fairly new to the whole adsense world and am unaware what kind of ratio's to look for. I setup a blacklist to try and raise my CPR but it seems like I am only getting 1-3 hits per 1k impressions. sometime's I will have high click ratio - but very low amount earned..My adds are placed well on my site, www.buddyhq.com ..so any help on raising conversion ratio's or CTR are appriciated!
