What are Backlinks?

Backlinks are links from other websites pointing to yours — one of the most powerful signals of authority and credibility in both traditional SEO and AI visibility systems.

Definition

Backlinks (also called inbound links or external links) are hyperlinks from other websites that point to your site. In SEO, backlinks are one of the most significant ranking signals — they represent votes of confidence from other web properties that your content is valuable and authoritative. For AI visibility, backlinks and citations from credible third-party sources are among the strongest signals that an entity is real, established, and worthy of recommendation.

Why It Matters for Small Businesses

A small business with backlinks from local news outlets, industry associations, chamber of commerce websites, and complementary businesses has a stronger authority profile than one with only its own website. These external citations signal to search engines and AI systems that the business is recognized and trusted by the broader web — the same signal that makes an entity appear in Knowledge Graphs and AI-generated recommendations.

Example

A local restaurant is featured in a "Best Brunch Spots" article by a regional food blog, listed in the chamber of commerce directory, and mentioned in a local newspaper review. Each mention creates a backlink — building the restaurant's authority profile in Google's eyes and contributing to the entity signals that AI systems use when recommending dining options in the area.
