usually the software programs barely help and alot of people think they will get top rankings if they just buy the software. web position is okay, I tried it and didn't like it, its doesn't tell you anything new, nor does it really show you want to do.
There is a program called webceo that alot of people swear by but I don't see it being neccessary in any way. Anyone can optmize and build links to a website with out any software.
