One of our sites with the following characteristica is showing very bad SERPS for a few days now. siteauthority 52 / page auth 58 / PR4 / well established site / domain around for 8yrs+ / over 100K backlinks The site dropped massively in rankings - from page 1 to 130 etc. Webmastertools used to show 110K backlinks. Now it shows we get "no data" for internal links and "no links found" for backlinks. This is the case for 5 days now exactly when the site lost rankings. Webmastertools shows now spam messages. Any1 any idea what is going on?
