Some people worry about CTR since the day they launch site. In my opinion CTR should be measured after quality traffic (2000-3000 visits/day) what do you think of this? A webmaster receiving 200-300 visits a day should worry about CTR or first develop content?
I think if you are getting only 200-300 visits per day then you should not show adsense ads at all. You will not earn much and you are also putting your Adsense account into danger.
yes kp_mastermind, traffic comes first, way before ad placement (ctr) for earnings. But if you know correct ad placement you can set it as you launch the site, no problem unlike what tricksdaddy states.
I wouldnt set the standard as 1000 or 2000 per day as long as you are getting steady traffic, then it is the time to pay some attention on the CTR
