So this is an unfortunate look that I experience in Pro Rank Tracker currently: I have this domain for more than 4 years and it has history since 2007. I keep building links steadily over time and in 2 years these keywords were on the top. I switched to HTTPS with all the 301 redirects since September and since then the positions got worse. Majority of keyword anchors are from 4% to 8% and most of them are naked URLs and brand. I decided to support the KWs with some web 2.0s and PBN links recently so this could be a Google dance. But I did similar links before and nothing like this happened. What do you guys think?
