I just set up some link units on my homepage and am getting more clicks. However, so far they seem to pay less than the content ads. Is it normal to get less per click on link units than content ads? Just wondering, I only had the ads up one day so I don't have much data to analyze yet.
Same here. I put a link unit under a banner ad and my CTR took off. But I'm still not earning what I earned the first few days with adsense.
