I tested two following tools for estimate my sites value. Tool 1 and Tool 2 Both of them are not accurate, but the first one consistently gets more close values of daily page views and daily ads revenue. What about your sites?
No way it can be accurate. Where do these guys got the price ? and hmmm don't think these sites will ever link to Admob, or MobGold, or AdSense. I guess they have certain rate for certain traffice or keywords in meta tags or url.
