Just Adwords and Google Analytics.

Web Development keywords tend to be expensive, so it was cheaper to focus on many long tail terms rather than compete for "wordpress", "web development", etc.

I started out with hundreds of terms related to building and converting sites to WordPress , and used Adwords and Google Analytics data to kill off any term that was costing me significantly without bringing in any leads.

Incidentally, I started out with Content Network enabled, but found that it brought no leads and cost more than search clicks. Not sure if that was click fraud or what, but killing Content Network was the best optimization decision I made.
