Make Custom Channel a target for Advertisers. any good?

[born2run]

Hi, when I make a custom channel on Adsense and include ad units in it, there is an option as follows:

Show this custom channel to advertisers as a targetable ad placement

Has anyone had success with this option in their overall revenue? Kindly share experiences. Thanks!

There's not really a way to know for sure, but I always do it because all it costs is time and maybe it helps. I do pretty well with AdSense, but I don't know if the targetable ad channels help. I'm pretty sure they don't hurt, though.
