Although it’s been out awhile, I just started playing with Google’s Wonder Wheel. If you perform a Google search, you will see a “show options” link at the top. If you click on this link, you will get a bunch of different Google tools including the Wonder Wheel.
I’ve found the Wonder Wheel really useful in trying to come up with keywords and key phrases for websites. It’s a much different tact than the Google Keyword Tool which just starts spitting out phrases and data at you. The Wonder Wheel makes you think visually about the relationship between words and phrases. I thought I had exhausted volume-getting terms for a particular niche, just to find a couple more using the Wonder Wheel. It’s just another tool to add to your keyword analysis arsenal.
Do you have a particular tool you use often for building keyword lists?
