So all of my Adsense ads are toward the TOP of my page, while I put some Lijit ads on the bottom.
I've noticed a drop in CTR for my Adsense ads, especially on the main page where the Lijit ads are getting a fill rate of about 50%.
Now, Lijit only makes pennies a day. It's not much. Now I'm wondering if it's worth it at all.
I just don't see how it would effect Adsense, since the ads are so far apart on the page, people who visit the page see all the Adsense ads FIRST -- but something isn't right.
