Keyword List Generator
The keyword list generator is a free tool to help you generate a large number of keyword phrases based on the keywords you enter. You enter your key search terms, and modifiers like “find, purchase, buy, online”.
It will then produce a large list of keywords made up of combinations here. This can be very useful if you are putting together a list of exact terms to bid for in your PPC advertising.
