Backlinks are primarily used for SEO, but can also be used for traffic. When a referring website posts a link back to your website, this is called a backlink and helps improve your SEO as search engines, such as Google or Yahoo will recognise certain websites with a lot of backlinks. Backlinks can indicate the importance or popularity of a website which helps search engines decides what to post on their search results. This will obviously help relativity to your website among a keyword of your choice. This will improve SEO and eventually increase traffic over time. Backlinks are normally built over a long period of time, but, this form of SEO helps increase the process of getting ranked in search engines.
