Backlink Checker is a tool that helps to check and analyze the inbound links to your website or other websites. If a website has many links coming from authoritative websites, it will increase the likelihood of appearing and ranking on search engine results such as Google and Bing. Researching backlinks is crucial to understanding trends, patterns, and linking opportunities.

Backlinks convey link equity or value from one page to another, which is the amount of authority or value that a link sends to the website it is linked to. Links from authoritative and related websites will receive more links and help websites rank higher in SERP rankings.

However, backlinks from spammy websites can harm the website's ranking and even lead to penalties.
