Backlinks, also called “inbound links”, “incoming links” or “external backlinks”, are links from any website that are directed towards your website. They represent how much a website can trust another.
Backlinks are significant for SEO because some search engines, especially Google, will give more credit to websites that have a better number of quality backlinks, and consider those websites more relevant than others in their results pages for a search query.
Search engines consider the number of quality inbound links to one website to calculate the relevance of a site to a keyword.
Backlinks are not always good though; if your website is following backlinks that have a low PageRank your website can be penalized and get a lower score too.
The cheapest way to get backlinks is by following up with blog comments. The process to get backlinks can be time-consuming, and new sites or those expanding may find it difficult to know where to start when it comes to link building. There are a few tools in the market that can help you earn some backlinks. Google Search Engine and Google Search Engine Optimization Starter Guide is the best place to find your answers.
