which boxes make the most $$$?

[fish04]

I've been playing around with different sizes and so far came to conclusion that one very well placed 250x250 sized ad gives the most profit ( example on my content pages below).

What are your experiences?

As usual, it depends. My websites .v1 utilised leaderboard that has Verdana font size 8px which blends in with my content. I only used one ad block per page, so my CTR was a healthy 7%.

Now, with .v2 design, I use 3 ad blocks ie: 2 skyscrapers and 1 rectangle. My CTR got diluted but I started to see some increase in income.

Right, when I had more ads, I had huge CTR but with one ad now, CTR is lower but $ per click is much higher.

Wide skyscraper and large rectangle works fine for me.

So far, the wide leaderboard's having the best results for me. It probably depends on the layout of your site, though.

Correct!
When I switched my table design, I had to pick up different ads too.

I know you're asking about ad units, but the link units have been very good to me .

Ya, I like the 250x250 too. But the best one is the ad links. Why? Because I can have 4 units if one of them are an ad link and three otherwise. Because ad links are small and integrate well into Webpages.

From Google's Optimization tips:



I tend to trust Google when it comes to this type advice. They have a lot more data to use than any individual publisher. It also corresponds to what I have found on my own sites.

Don't trust Google blindly.

Their heat map suggests that best visibility of ads is on the right side while the Google search pages show ads on the extreme left.
