Has anyone else seen major fluctuations in rankings since Mid april? I was doing great for several websites (PBN posts, real social media posts, and guest posts) and then from about April 11th - April 17th all of my websites crashed to pages 6-8. My top 2 anchors for each website are always the natural link, with www. and with http://www. as well as brand name. So anchor diversity is there with only about 5% keyword anchors. The links are distributed throughout the website such as home, contact us, services, category pages etc. Anyone else see similar things happen to their sites last month?
