I have 10 pr 3 to pr 4 general blog and i am loading adsense on them.They get around 500 unique visitors daily How much is it possible of me earning from them Unique content gets added on them daily.
It all depends on the niche.. but if you say general blogs.. I think you should expect a earning for $2CPM or so.
Join post selling services like payperpost, you should be earning a lot of money with them if you invest some free time... p.l.u.r.
Do the math, if the average post that you get to do on PPP is $10 and you can do 3 opps per day your looking at around $300/day and if you work at this for only 20 days a month. You can make roughly $6,000/month. can you make that in adsense..I really doubt you can.
