I have been running around in small circles trying to work out why, after a year of careful SEO my companies site has suddenly dropped for all it's main keywords out of the first page to the second or third in our weekly report.
One theory was that five backlinks with a spam rating of 10 might have had an impact - these have been removed, but I have been advised that these may not have been the cause.
Our crawl diagnostics remain squeaky clean.
I add one, carefully checked and optimized (as per Moz recommendations) blog posts once a week and nothing has been changed other than that.
We have slowly and carefully built up a good backlink profile, but as well as the drop in rankings our weekly report also showed that we lost 109 backlinks from the previous week.
I have not been able to find out what I could possibly have done wrong!
I've checked all our crawl reports and webmaster tools and nothing has been flagged up.
I did discover, whilst typing in some longtail keyword phrases that our preview site URLs as well as our live site URLs appeared in SERPs. I checked with our web agency who assured me that this was fine, but that they had put a redirect on these yesterday. I thought this was a bit strange as that seems odd as we have been live for a year. I guess my question is could the fact that these redirects have not been active (until yesterday) have any bearing on what has happened or is this completely unrelated?
Thanks
