Has anyone observed any CTR/payout change by implementing section targeting? Besides the obvious excluding footer and other non-content elements on your site, how do you use it? Does it make sense to "section target" the data within H1 tag or does AS gives that data a higher weight anyway? Is there a maximum (or optimal) number of section targeting snippets supported?
I use it a lot. Since I started using section targeting, my CTR has remained unchanged and my eCPM has increased a lot. I use the ignore directive around all the non-content, menus and ads. Basically all my pages start with a header and end with a footer. An ignore directive is placed around these. Then I'll put emphasis directives around titles and stuff like that. I want to start putting emphasis directives around high value keywords, but haven't taken the time to do that yet.
