The suggested 'broad match' is 'Buffy gifts'! Andy
I just looked at the broad matches suggested for my keywords. I have a site that sells porcelain angel figurines, so I am buying keyword "angel gifts".
Sure, I can see how they make the association, since "Angel" and "Buffy" are related shows. However, it is totally useless for me to get a visitor from 'buffy' keyword, since I have no items at all on the subject!
