Backlinks at their core can be looked at like votes for a site; so, you would think that the more votes a site gets, the better. However, just like with the electoral college compared to the popular vote, more doesn’t always mean better or that you get the results that you want. Not all backlinks are good for search engine optimization; and, in fact, some links can actually hurt your site and even get your site blocked from the search engines. Bad links come from unrelated sources and point at your site. You need to monitor the links to your site to make sure they are helpful and not hurtful.
