So I'm guessing majority of SEO companies use the same tools as us ... scrapebox, xRumer, and seNuke.
Then the more advance companies(topseos.com/rankings-of-best-seo-companies) are at the point of making their own since their bringing in revenues in the millions.
The thing I'm interested in finding out is, what exactly their tools do? Anyone worked for any of these large SEO companies before that can shed some light?
