Do you have a goal in mind - that if you reached - know your ads have been optimized well enough?
Maybe for example, it's a 2% CTR average for a month.
I find my self constantly scrutinizing, changing, optimizing and re-optimizing my ads - over and over - looking for that perfect combination of web design, Adsense colors, sizes and placements.
There's something about Adsense that makes me feel like I can be doing something better - that I could be making more money - if I could just get that last thing right.
I'm constantly analyzing my stats and trying new combinations.
Maybe this isn't a bad thing, because I'm learning new things, ideas, and keeping the design of my pages fresh and up to date.
But at the same time, I feel like I will never reach the plateau of happiness - and that it's an endless game because:
It really is impossible to know if your CTR went up because of your ad placement, size and color changes - maybe people were just more interested in the actual ad that day.
Maybe the reason your CTR went down the next day was because the ads running weren't as appealing - not because you changed colors.
This is why I feel like I drive myself crazy sometimes with it, and was just wanting to know how you gauge your publisher success.
I feel like I might be 'over-optimizing' - but when the difference between a 1% CTR and 2% could be hundreds or thousands of dollars, it's easy to do.
What is your goal? Have you reached it?
