I'm trying to make a choice as to where to invest my money for link building. I want a solution that's going to give a variety of link sources and as much automation as possible. I've been looking into Link Farm Evolution, TextLinks.com and Brute Force SEO. I've only heard great things about LFE so far and it really appeals to me because of the on time price, but my concern is the longevity of the effectiveness of WPMU link farms and other blog link farms. TextLinks.com looks really interesting. For the price it looks like you get a lot of back links really cheap and they are permanent and there is no need to create content as far as I can see. I have read many mixed reviews on Brute Force, more bad then good. He released the new version today but it's $157 a month. Seems like it is very automated. There's a seven day trial so I guess I'll try it out. I know of other solutions also like SENuke and ContentBuzz. I'm basically just trying to figure out which solution will give me the most leverage and is a reliable tool that produces results.
