As some of you know I create and test brand new websites with various SEO strategies and record the changes in rankings. I wanted to share with you current strategies that either dropped or increased in rankings since the Panda 4.0 update. 1st strategy - Rank a website with EMD pure low cost and high quanitity spammy links purchased from forums. Up until mid April this website was ranking for the EMD on position #9 and had 4 related keywords on position #11-22. After the Panda update the website dropped rankings to pages 5-8. No manual web spam action taken on WMT 2nd strategy - Rank a partial EMD website with PBN links (not purchased from a forum but created myself) that are mostly natural URLs and Domain name links. Was ranking on page 1 for the partial EMD and the main targeted keyword until May 4th when I received a Manual penalty. The only links created were 10 PBN links all with natural URLs and 3 domain name links. (I think that a competitor reported the website) 3rd strategy - Rank a website with only social signals, was ranking up until this update for 12 keywords ranking on pages 5-9 and now the rankings are completely gone. 4th strategy - Rank a website with only guest posts. Was ranking for the domain name only and now the rankings are completely gone. 5th strategy - Rank a website using Public "Private blog network" links, was ranking for 11 keywords on pages 2-8 and now there is only 1 keyword ranking on page 3. 6th strategy - Rank a website using just local citations, no keywords ever picked up rankings in top 100. I have a couple older websites that still have rankings but these are 2-3 years old with many different methods used. So hard to tell what works and what doesn't at the moment. I would love to hear your thoughts on these strategies and share your experiences with the current state of SEO strategies. p.s. keep in mind that most of these websites were created for testing purposes and only have about 4-5 pages on each site and I don't update/pay much attention to them other than view the ranking results.
