Adsense

I see a
Enable Adsense Section Targeting? BETA
Select "Yes" to add Google AdSense section tags to relevant parts of your forum pages within forumhome, forumdisplay and showthread.

What does this do as when activated I see nothing different?

AdSense supports a tagging structure in the code of your page, that identifies the content that is most relevant to your page.

By identifying this important content, your ads should get more accurate.

The end result is that users viewing your page may be more likely to click ads, if the ads are in fact, more highly related to the page they are on.

Ah, I see thanks

I thought it was for Adsence to appear.
