A backlink is a link created when one website links to another. Backlinks are also called “links”, or "inbound links", or "incoming links." Backlinks are important to people moving around the internet and to Search Engine Optimization (SEO). Backlinks are links on other websites that point to your website. In the world of SEO (Search Engine Optimization), they’re like votes of credibility from other sites. The more high-quality backlinks you have, the higher your website is likely to rank in search results. They are basically votes from other websites. Each of these votes tells search engines: “This content is valuable, credible and useful”.
