Best Single Tool For Authority/niche sites Flipping
If I was to buy one tool that will be the backbone of my adsense niche site flipping venture would it be a keyword research tool such as long tail pro or market samurai. I already have SERP Attacks PRo, althought its pretty slow it gets the job done.
OR
Some kind of article spinning software such as the best spinner? Other reccomendations are welcomed.
I don't have enough money to buy both and just trying to get the most bang for my buck. I plan to build niche and authority sites for myself and possibly sell them in the future.
Thanks!
