The hardest part of doing keyword research to me is just doing it. I use the free Wordtracker tool also. I have been spending a lot of time lately studying the SEO process of my website and adding the keywords in at the right places is very important also.

When doing your keyword research, don’t focus your efforts on keywords with high total searches per month. The majority of keywords with large searches per month aren’t necessarily buyers. Longer-tail keywords, or more specific phrases, often get less searches, but have higher conversions because the consumer tends to be looking for exactly what they are going to buy.
