The official AdSense Blog gave tips to bloggers on how to optimize ads in their blog or in other words, Blogtimize!
They gave 4 tips on how to blogtimize:
1. Choose the right ad formats
2. Place ads where your readers will notice
3. Improve targeting
4. Customize your ad colors
As you can see, I kind of, followed the layout of the diagram at the right a little bit, except for the search box. I choose the right kind of ads, I think. I placed it where the readers will notice, between the posts. I think my ad targeting also improved even if I didn't use section targeting. As you can see, the ads that usually appear now tends to be related to my OJT entries because those are the entries present when I first put ads in this blog. But as I post new entries and the OJT entries pushed off from the index, the ads will change and be related to the new posts. I also customized the colors of my ads so that they will blend onto the color of the background.
