Welcome to WebmasterWorld Guest from 22.214.171.124
This new feature is available directly from your AdSense account and lets you quickly create, run and analyze A/B experiments for specific ad units -- all without needing to make any changes to your ad or page code. It works by comparing your original ad unit settings to a variation you choose, and ultimately tells you which one performs better. Here are just a few examples of the types of tests you can run:
- Compare the performance of text-only ads to ads that have both text and display enabled
- Determine how ads with a visible border perform compared to those that are ‘borderless’ (where the color of the border matches the background of the page)
- Analyze the effect of changing the color of ad text on ad performance
I dunno how much traffic you get, but I'd probably leave it at least a few days to a week.
but Google will penalize in terms of RPM earnings you if you select to run just text ads only. At this time, to be achieve the highest earnings 99/100 times you have to be opted into all ads types.No sir, that's not 100% true for all units in all positions. For example I have a text only ad unit in a higher CTR location who's earnings are decimated if I turn on images because the CTR on images is very low in comparison. I do agree however for ads in low CTR areas of your site, if you're getting a very low CTR on a unit then having image/text enabled is probably best.
yes ads for only one site can have experiments. Has G decided the other doesn't need it?
