Keyword Research

I've got a little routine i go through when im doing keyword research. It's pretty simple really.

Using Google's Keyword Tool i find a pile of related terms and their aprroximate search volume. I then look at the most relevant keywords with the highest traffic. One by one i do a search on that keyword in google and check out the competition.

When i'm looking at the competition i look at PR mainly, but also a couple onpage factors - like keyword density. It is also useful to do an "allintitle:" search such as: allintitle: funny stuff - this will return only the pages that have funny stuff in their title. I like to stay away from any keyword that returns around a million results for this search.
