Adsense Injection - The WordPress Plugin
“I was looking for a simple simple Wordpress plugin that just inserted Adsense code randomly into a pre-existing blog. All the ones I found would only replace an Adsense comment with Adsense code. That’s great if you want to go through every article you have and post little adsense tags, but for a site that has some bulk to it, it sucks.
It also increased banner blindness by keeping the ads in the same place time after time.
My new Adsense Injection plugin just takes a random paragraph (or br tag) break in your article and inserts adsense code. It does one per story on multi-post pages (home, archive, category) and let’s you pick how many to show on single post pages. It lets you pick how many total ads to show at any time as well (0-3) and it lets you set the formats and colors you want it to randomly select from.
I’m using it on this blog if that gives you an idea of how it works.
Version 2.0 Let’s you show YPN ads as well as Google, although I can’t test it because they wouldn’t give me an account in their precious beta launch. : (
If you want to keep ads from displaying on specific posts, use the tag in the post HTML somewhere. I do that on a few posts on this site. Go look for them. It’s like a treasure hunt where no one wins!
If you want to keep ads from displaying above a certain point in a post, use the tag in the post HTML where you want it to start.
Here’s an example of how to fill out the Adsense Injection Options page. Use your own adsense ID.”

The randomness seems like a great way to avoid banner blindness, but what about testing and finding the adsense “sweet spot” on your blog. You would have no idea which areas are out performing others.
It’s probably just me though. I just don’t like random ;)
