A very interesting observation about Image Ads

Reason why we may try adding ads even if they dont covert into payments.

It has been noticed in the past by me and may other fellow adsensers here that image ads dont make realy good money convertors.

I tried an experimnt last week and on one page of my site and studied the results.

I removed the text leaderboard and put the image leader board. Due to the type of topic of page, I get an image ad 90% of time in that slot. That too one or two specific ads get repeated too often.

I have a medium square block of text ads only on the heart of the heatmap ( call it - on the face ), not blended and shows of itself as a google adblock.
Below that I have my content.

Results after one week.

1) i hardly got any click on the image banner in leaderboard area, as it was expected. less than one dollar in whole week.

2) The text adblock CTR shot up by thrice and the eCPM was high too ( there may be other reasos for high ecpm - i agree ).

3) The earning of this week were almost double that before for this block ( checked thru channels )

I am carrying on this experiment, but only on one page for now.

If someone else is trying this, or is willing to try, please do and lets post the results.

if I do understand your setup right, this result should not be surprising:

a) your leaderboard gets a poor CTR because of its not so favourable placement; the rectangle on the other hand is very well positioned on the page (high CTR)
b) in the past high paying ads went into the leaderboard and were not clicked while low paying ads were clicked in the rectangle
c) the new image ads at the top do not compete against your other ads => they still are not beeing clicked; the high value ads not went into the rectangle and push your eCPM

So, in other words: just get rid of the leaderboard alltogether and you will get the same good results with less annoyment to your users

Sobriquet –

If AdSense normally displays cost-per-click (CPC) text ads on your page but you opted in to only image ads during this experiment, it makes sense that your revenue would decline because this narrowed the inventory of ads competing to display on your site.

AdSense automatically determines the ads that will generate the most revenue for a given page, and shows those ads accordingly. This is why opting in to both image and text ads is recommended; doing so creates the greatest pool of advertisements competing to display on your site.

If CPC text ads perform best on a particular page, AdSense will generate CPC ads. However, if CPC image ads or CPM ads will generate more revenue, these will display.

Hope that helps!
