If you are looking for something to manage your 125×125 ads button, there’s a plugin that not only mange your 125×125 ads button, but it also tracks the clicks, does ads rotation and has an auto expire management.

WP125 features include:

• One or two column ad display, and support through template tags to implement your own unconventional design.
• Show as many ads as you want, and in either manual or random order
• Keep track of how many times an ad is clicked
• When creating a new ad, you don’t have to calculate the end date yourself. Just input how many days you wish the ad to run for, and the correct date will be applied. The ad will be automatically taken down when the time comes.
• When an ad run is over, the record is archived on the Inactive ads screen, so you can check on the final click count, or revive the ad for another run.
• When an ad slot is empty, a placeholder ad of your choice will be displayed. This could be a “Your Ad Here” image linking to a page with statistics and pricing, or an affiliate link.
• Optionally receive email notifications when an ad expires. Useful if you send follow-up messages to advertisers, or if you just want to stay in the know.

Below is an example of it looks like which I have just installed to one of my blog. So far no ads yet I cud just add it anywhere I want. For this example, I add it to the bottom of my post. Of course, if you don’t want to change any of your php codes, just stick to the sidebar. You can arrange it vertically, if you want it that way.

This is where you manage your ads.  Simple.

I will wait until the level of 500/day before I start to monetize this blog with Adsense or with any other advertising network. That in about 3-6 months. Possible?

I have just taken out Nuffnang advertisement from the sidebar. Will discuss about it later ok.

oh, by the way, you can make money with Adsense even on a non niche blog Just don’t do it too soon.
