Link building is acquiring links from other websites to your site. It is also called ‘back-linking’ in the terminology of SEO. By Link building, the ranking of your site in search engines increases. A good number of links to a website portrays that the website owns valuable content.

This SEO technique of link-building can be effectively used in blog post writing, where links can be placed throughout the article by integrating words and phrases relevant to the link. The search engine will use the links to know better about the site, and your site will ultimately rank better in the search results. 

Example

You can post on relevant sites as a guest. Those guest blogs will be linked to your own website and fall in the category of link-building. You can also post answers to questions on popular interaction social media platforms to implement link-building.
