Dont ever buy keyword lists as there is a reason the seller wants rid of them

I often see people selling keyword lists and maybe it would save you a bit of time finding and building lists but it is a very follish strategy and could hurt your business quite a lot.

When someone builds a keyword list they will do it for their own sites to get traffic.
This is fine and everybody does it but some people take the keyword lists they have built and rather than just delete the list when they have finished they will try and sell it on to unsuspecting people which is actually a complete con.

The keyword lists you would buy would consist of words that someone else has built sites from so you would of course be competing with them and they will have of course used the keyword list to death.
One befefit of most of the idiots that sell keyword list is that they will be bad at building sites or they would have no reason to try and cash in on the keyword list or they will be bad at selling the lists and you will only probably sell it to one or two people.

You need to build your own keyword lists to make sure you are doing something unique and special and not just copying what someone else does.
