I won't talk about the quality of the keywords or if these services provide any value. I was tempted to buy some times but decided against it for various reasons. That's also irrelevant, the quality can be top notch and there is sure value as there are people buying them. BUT... How the fuck can anyone that offers writing services or link building services sell keywords?? What if someone orders an article or a link building service with a "gem" keyword? Who can quarrantee that the seller is not going to sell that keyword one or 100 times after that? Am I the only one who sees a problem here?
