Backlinks are incoming links to a webpage from another website. They are a crucial aspect of search engine optimization (SEO) as they signal to search engines that the content on the linked page is valuable and relevant.

How do backlinks impact SEO?

Backlinks play a significant role in determining a webpage's search engine ranking. Search engines such as Google consider backlinks as a vote of confidence from one site to another. Websites with a higher number of quality backlinks are more likely to rank higher in search engine results pages (SERPs).

Additionally, backlinks can also increase a website's domain authority and credibility, which can further boost its SEO performance.
