For me there's only and only 336 x 280 unit, i know all this rules and they work if you want to increase CTR but not eCPM, i have no idea how to increase eCPM and I don't care When it's a good day I have high eCPM, when there's a bad day (like last 3 weeks) i have low eCPM.
Last tips not actual for blog, rest of it i use. I also place adsense link block on bottom of post and it work well User read post and click on bottom link.
Yeah I noticed that two lol Theres is a pink colour shouldn't it be white to blend into the background?
Here's a couple of golden rules I use for adsense: Put ads in the heat map of the page, (left column, or at the top of the page, install crazy egg to see where your visitors are clicking) Links are always blue, text matches color of text of the page, no borders. absolutely do not let visitors leave your site any other way but by clicking on an ad, or hitting the back button. Those things alone keep my CTR at 30%-40% (up from 3%-4%) 10x more money !! (you owe me a beer) -RonMo
Nice tips! Thank you. There are a couple on there that I need to work on. <edit> I agree with the above, traffic is now the main challenge.
after they told us that it wouldn't work, lol... an adsense block at the bottom of the page can be good, for instance, if it's at the end of an article. noobs, don't believe crap that you read on the internet that little scammer tactic will drive your epc right into the ground, because you are making people click on ads when they have no intention of buying the product. when the clicks don't convert, you get "smart priced".
