Hey, TCR, just a thought: Why not get rid of that sore looking firefox button and change your half sky banner to a full sky banner to fill out the block? I personally think that firebox button really clashes with the general "look" of your site. As to your original question: ad links have proven to be a major source of revenue (and in my case, THE biggest source in comparison to the other ad types Adsense offers), so you would be wise to test them out for a week to see how well they do. My guess? Very well!
Good points, the FF ref button is an eyesore..replaced with skyscraper and added link banner...lets see how it does
Wow, that's very interesting! I saw about a 10% boost from adding AdLinks. I saw about a 10% boost from adding AdLinks. What are the keys to achieving a good CTR from AdLinks? Have you had better results from vertical or horizontal link units?
