I hired a so called SEO expert around two and a half years ago. Before I hired them I was achieving around 10,000 visitors a day. They claimed to be experts and were based in the UK. There is a long story to it but i will keep it short. I hired them because they were trading under a big brand name, which turned out to be a franchise and the person in question had no experience and hired all the work out to India.
Anyway, after a few months of hiring them my traffic went right down. I fired them but found out they had put in a back door to my site which has now been removed.
I have been trying to learn SEO and been trying to find out how they have damaged my site. The site is not banned by Google so that is good, but the traffic has been hit heavy. I have lots of content on the site but the amount of content does not reflect on the traffic.
Is there a way to find out why i am having so many problems trying to fix my sites traffic. i seem to be spending more time trying to fix things that the content.
