So here's the back end... I have had my online store for almost 10 years and have always had the best rankings for all of my keywords. Over the last couple of years, rankings have gone down and down. I do blame a lot of this on myself where I got content with the site and income and hardly never did any updates or created new content or really anything to grow the business. I'm now trying to change this around and frequently writing new articles and having the website rebuilt in Magento.
Three years ago an old associate of mine secretly went into business against me and started selling the same products that I was selling. He also copied every paragraph on my site and used it on his own site. A lot of my content was not unique so I can't be annoyed about that, but he also took my unique content. He also took nearly every one of my own pictures and put them on his site. Not long after, his site began to rank well. Soon after that he made another website selling the exact same products, same pictures/information but just on a different template. Both are even hosted on the same hosting account.
Now to the present, both of his duplicate websites and now ranked much higher than mine. I have literally gone from the very 1st position to page 5 for my primary keyword - Both his websites are page 2. For all minor keywords I am still on the first page, but both his sites are ranked higher. This has seen my sales reduce by about 50% this year.
What I am desperately trying to work out is how the hell are his websites doing so well? From every backlink check site, page rank site etc, my site still has far better stats than his with much better quality links.
Looking through WT it says I have not been penalised either.
Does anyone have any ideas on what has happened?
