Why is it that when I do keyword research on something like wordtracke, for a root keyword I put in such a link popularity, I get website tools in my list of possible search terms. As we all know just because I might search for link popularity information using link popularity as a keyword dose not mean other people will therefore its seems like getting website tools as a replacement keyword for link popularity or any number of others that do not mean the same thing will defect my purpose if I use them. Please explain this. Also on a related subject there are several places on the net and software that allows you to put a root keyword in and then only shows other keywords related to it and the number of searches made with those keyword. Something has got to be wrong because all of the words I type in are the most searched. That does not sound right. Please explain.
