A backlink is a link pointing to a web page from other external websites. Backlinks are commonly used as a measure of the quality and relevance of a web page, as search engines consider inbound links to indicate that the content is valuable and worth sharing.
These inbound links are a key component of SEO and link building strategies, as they contribute to improving a website’s domain authority and visibility in search results. Proper indexing of each backlink by search engines is essential for them to contribute positively to a website’s SEO, as non-indexed links will not be taken into account when evaluating the site’s relevance and authority.
