I've got a big website with a lot of links and for the most part they are all very high quality links. I'm very careful what I allow to go to my money site. Yesterday I connected my website to Google Plus so it shows my picture next to my website. Today I've had a MASS decrease in rankings across the board. Even on pages that I have been extremely stable on for more than a year and I haven't touched backlinks on them for more than 4 or 5 months took a big decrease. I went from page 1 on at least 15 different keywords to pages 2 - 7. Has anyone else had any experience with connecting their site to Google Plus and then seen an immediate decrease in rankings? If so, how long did it take to come back?
