Especially on 1.ad placement,whether it is in correct place or nt(nw i want 2 remove one ad..top position) 2.my blog is about women's lifestyle(is it under a BIG niche ?)
you ad placement is ok, but unfortunately the one in the content column is the one with less paying ads, because the last one in html code. a pity for your earnings.
best paying ads are in the first block in your html code. So you need to make sure your first block in html code is also the one which gets the most clicks (highest CTR) otherwise you are losing money.
Thank u Starcaller for ur response..it means that first ad on my blog is a best paying ad?i have put 3 ad unit first on my blog and 1 link unit i put below the blog post and another link unit i put right sidebar(have a look).But i,m earning more revenue from these 2 link unit.Then hw is it possible?Shall i replace my ad unit with link unit?
