interesting potentials in the name.

Optimize seperate pages for each one.
Use terms like SEO and whatever looks like it might work as far as ad competition. I think this will be at least somewhat profitable. Maybe not a lot of clicks, but some good adrevenue possibilities per click.
Overall: Good pick
