Hi Guys,
Thanks so much for the responses!
I'm going to have to take a closer look at where their links are coming from because they don't seem to do much social sharing and the links to their website seem a bit dubious.
I did some digging into the links to their website and when i group them by domain they only seem to have one external link and it seems to be a Portuguese web design firm. I've attached screencaps of the link explorer for their page and mine if anyone could advise as whats going on that would be much appreciated. The first grouping on the competitor metrics image is the portuguese site and the second grouping is the competitors own domain.
again my apologies if my lack of experience is making for stupid questions.
Thanks again for the help!
