A backlink in SEO is any link that points to a webpage. It serves as a recognition, which informs the search engines that your content is something worthy to be ranking. Whenever other credible sites link to yours, it is considered an added bit to the credibility of your site.
Google and other search engines take backlinks as one of the most important factors to determine the site’s ranking. It can be said that the greater the number of quality backlinks, the higher the probability of the website popping up on the search. In other words, backlinks are rather important to increase your website’s exposure level and get more organic traffic.
