What Are Backlinks and Why Do They Matter?

Backlinks, also known as inbound links or incoming links, are hyperlinks from one website that point to another website. They are one of the most important factors search engines use to determine the authority, relevance, and trustworthiness of a website. When a reputable site links to yours, it acts as a vote of confidence, signaling to Google and other search engines that your content is valuable.

Understanding your backlink profile — who links to you, how many domains reference your site, and the quality of those links — is essential for any SEO strategy. Our free backlink mapper gives you this data without requiring a paid subscription or account creation.
