SEO Backlinks are getting links from external sites to your own website (or any of its pages). They are an important part of SEO strategy. This is because the more links you are able to get, the more your website is considered trustworthy and authoritative in Google’s eyes. Getting the links isn’t a simple task, but you can get started by connecting with bloggers, other websites, and online magazines in your circle and try to get mentioned by them. Learn about outreach marketing tips. Basically, you have to get your website mentioned from multiple sources online.
Please remember that it’s important to remain within Google’s guidelines and don’t fall for so-called ‘link schemes’, which is totally a scam rather than SEO. Read more about Google’s webmaster guidelines here.
