In brief, 3500 visitors, almost 10,000 page views and a bounce rate of 43%. These are consistent numbers, but we are seeing no reward from SEO because, simply, it is not being applied.
We need to re-visit and make sure we understand the rules that need to be applied to the content that is posted. What we are getting is what I call “accidental” traffic – the majority of visitors are finding us despite what we do instead of because of what we do. The Facebook audience needs to be leveraged further – click through from FB to site is low. Would suggest re-instigating the idea of regular promotion of the site on FB in addition to individual posts.
