If you visit any website which discusses SEO and how to improve rankings on Google there will undoubtedly be some discussion, articles or information relating to backlinks. To prove the point, you are reading one of them right now, so it is fair to say professional SEO and backlinks are very much related.
Where the confusion, and sometimes reticence to use backlinks arise is not knowing which backlinks have a positive impact, and which backlinks are more likely to see you plunging down the rankings, or worse, wiped off them altogether, which has happened to countless websites.
Part of the problem is that there are so many ways in which you can create a backlink to your website, and just as many places online where you can link from. Add to this Google’s determination to clamp down on spam links, link farms and links which appear to be high quality but aren’t, it has become a cat and mouse game between the search engines, and those who use those blackhat tactics.
