What Is A Backlink?
A backlink is simply a link to your website from a different website. Because backlinks are generally difficult to obtain, they are a major factor in how search engines determine the authority, trust and quality of your website. Backlinks from authoritative websites will give your site more authority and, on average, better rankings.
Backlinks from trusted websites such as universities and governments will also make your site look more trustworthy to search engines. The reverse is also true, and since 2012 backlinks from spammy websites can actually harm your search engine rankings.What Is A Backlink?
