1. Say your site is about widgets and you have written extensively about all sub-topics that you know. Use Wordtracker to locate some good related terms and bingo, you have found an entirely new topic that you can write about.

2. I second (or may be third) TJ's advice about pulling the highest paying ads on the location with the best CTR.

See this case study --

You have a vertical ad block in the left column under the nav menu, then an ad block in the center of the screen above the fold (below your headline). Now the left column block pulls the best ads whereas the center block gets the best CTR. So you lose a big opportunity, eh?

3. In my experience, wider ad blocks generally get better CTR but get more in the way. Vertical ads gets lower CTR but can be more off-the-way and low profile. So you can choose how aggresive you want to be with the ads on your content sites.

Of course, a lot depends on the site design.
