The launch of the responsive design is the only event we can correlate to the beginning of the decline in overall visits to the website since July, however we're not sure if this is the issue.
To give you some background, the website http://www.precisionpestcontrol.com.au/ is a pest control site in a highly competitive industry where there are many black hat tactics going on with huge keyword competition on a small range of keywords, however historically the website traffic for the above site has been gaining momentum.
We create/ update 2 or 3 pages every month with rich content and post 8 blogs every month on pest control related topics. We have done the initial keyword research and all the keywords we used are medium to high volume terms.
We don't do any black hat tactics or dodgy link building, we have invested time submitting the site to legitimate business listings in the past. It just seems strange that all of a sudden we go responsive and start to lose searchengine traffic.
Possible Issues
What we've been able to find so far were some pages that were not redirected properly, probably about 5, and 2 pages that seemed to lead to a 404 error. These have only just been fixed recently, otherwise the mobile site has been functioning effectively.
Could this be the reason we have been in decline over the past few months?
We also seem to have lost a whole lot of external links somehow, the external link measurement in MOZ has gone from 1500, up to 6,000 then down to 300 or so in the space of a few months.
Basically we're trying to figure out what we're doing wrong, or what we can do to try and stop the decline of visits. We've checked the algorithm updates and don't think that Panda or the shift to the Google AI would have penalised us, but then again we could be wrong.
Any advice anyone could offer would be hugely appreciated. Happy to provide any data for anyone to have a look at.
