My website has been slipping in the google rankings slowly over the last few months so have just started a lot of research to try and better optimize my site.
Part of this has been looking over competitors backlinks, an area which I've really slacked on, but upon reviewing competitors backlinks see some very strange sites in there and on further investigation have
absolutely no idea what they actually are? To me they look like article directories?
and a lot lot more, which are riddled with anchor text and back links to competitors site and I can't figure out if this is something that I should be doing to? Are these article submission sites that I should stay clear of? Very very confused at this moment!
