We redesigned our website back in November and also started regular blogging. From that point we started rising slowly but steadily in in the rankings for all keywords and key-phrases that we were targeting. Our blog posts were getting great social shares and the percentage of people registering on our website crediting a 'Google Search' as how they heard about us also started to rise.
Then in about mid Jan (which I believe coincided with a Panda update) we plummeted. Ever since that we have jumped around all over the place in the rankings up and down every week... up five one week, down 8 the next up 2 the next down 6 the next.... but basically generally a downward curve... we went from 'slow and steady but always up' to 'erratic up and down but with the general trend down'.
I did find out that someone within our company had started to do some article spinning with UAW but I found out about it within a few days of it happening and put a stop to it. I figured seeing as it only went on for a few days and that I never got any warnings then we were OK but the way we have been dropping in the rankings and in some case dramatically it seems to me that we must have been penalized....
I recently got some advice from a professional SEO who said that he wouldn't personally remove any links unless he got a warning from Google... so I'm not sure what to do and hate the fact that so much good work and good blogging has been undone.
Any help and/or advice would be fantastic.
