I am going to take some money off my wage and buy a BH tool today. Basically I have a blog which I used to post manually on but lately I switched it to autoblog using wp-robot & it's posting without spinning. Up till now G hasn't penalized the site & is getting about 50UV per day from G(different keywords). I tried to do manual backlinking but when going to yahoo site explorer nothing comes up, only a youtube video I created when I started the blog(April). For now I only have the money to buy one of them, What do you suggest I buy between TBS & Scrapebox & Why?
