This is my list so far from the info I've gathered from the site: Scrapebox SEO Powersuite SENUkeX Bookmarking Demon Linkpushing RankTracker (for sending reports) Are all of these needed? Could someone possibly take the time to explain what the difference is between each one? I'm ready to start my business and know all the fundamentals for on-site SEO, but let me ask you this: Is it true that the only trick to off-site SEO is to gain backlinks by whatever means (spamming etc)? Or is there more to it? Thanks!
