Perfect. This works, and simple.

This takes no time to work out. Nice simple plugin and you can get going very easy and doesnt take long to work out how to get up and running. Lays out the ads nicely on the page and to the number of words so the more words the more ads and vice versa which is great formating feature.

Stable, out of the box system.

Definitely have a look at this plugin. Ive tried a few but this is one of the best on the market and the free version does what you need but worth upgrading to the pro version to get some extra features. Remember, your adsense account is worth more to you than the cost of the pro version plugin so its not worth mucking around – buy the pro version for peace of mind.
