If you want to improve your web rankings
for keywords that are relevant to your
business, you first have to know where you are. Here is
a free keyword ranking tool that will let you keep up with it all.
You can even graph how you're doing vs. competitors on keywords
of interest over time.
If they started charging for it I wouldn't be all that surprised.
Buy some of their stuff or something. They deserve some money
for this awesome free service. I think they sell tshirts or something.
(I am ashamed to admit I've never bought a thing from them.)
