First HowlingWulf tells me that A/B testing is free - just submit to tgps. Then Shemp admits you can't really do that but such testing is "overthinking".
I suppose that they know this business much better than I do and could go ahead and try to experiment as they suggest. I find, though, that I do not have such an easy time getting good sponsor content that I can work with. I spend a fair amount of time doctoring the photos and trying to leverage a few years of web development skills to try to build nice templates. I do this part time and have other projects. Overall it makes sense to me personally to try to optimize my ROI with the content. I also wonder a bit why others with more experience seem less interested in optimizing ROI for both content and the whole advertising product, if you will.
Anyway, with all due respect to the experience of HowlingWulf and Shemp, I am less interested in why I don't need to test gallery designs than with ideas for better ways to do so. Actually JollyHumper seemed to be on to a similar idea with his thread
Analytics vs Clicky.
So if you are not tired of this thread and have ideas about
1) Gallery design testing.
2) Optimizing ROI for sponsor content or reasons that isn't worth the trouble
then I still await your further enlightenment.
