Backlinks

Incoming hyperlinks from external websites to your site, serving as endorsements that signal authority, credibility, and relevance to both search engines and AI systems.

Backlinks remain a cornerstone of SEO and are increasingly important for AEO, as AI systems use link signals to assess source credibility and determine citation-worthiness.

Quality Factors:

  • Authority - Links from reputable, established sites
  • Relevance - Links from topically related content
  • Context - Links within relevant content (not sidebars)
  • Anchor text - Descriptive link text

Example of High-Value Backlink: TechCrunch article about AI search tools links to your AEO guide → High authority, relevant topic, contextual placement

Taking Action

To build a strong backlink profile:

  3. Pursue quality opportunities - Focus on relevant, authoritative sites
  4. Build relationships - Connect with industry peers and journalists
  5. Monitor competitors - Learn from their successful links
  6. Track progress - Measure growth and quality metrics

Backlinks are external votes of confidence that signal authority to both search engines and AI systems—in the AEO era, a strong backlink profile is essential for earning the credibility needed to be cited and recommended.
