I've been trying out the adsense link units on a site and they aren't performing all that well. Is this the experience of others? I hadn't tried them out before now. How do you find the clickthrough rate and CPC when compared to typical text/image ads? Edit: Additional info as no-one replied! In a test on my funny pictures site I'm finding that click throughs are high but CPC is much lower than than typical image/text ads. They don't take up much room so I can see the use of them, but I had slightly higher expectations.
