Site Authority

Assesses domain-level authority signals that AI engines use when deciding which sources to cite in generated responses.

Why It Matters for AI Visibility

AI engines do not just evaluate individual pages -- they assess the site as a whole. A well-structured site with strong internal linking, a complete sitemap, and topical depth signals domain-level expertise that makes every page more citable. ChatGPT and Perplexity prefer citing pages that are well-connected within their site. An isolated blog post with one internal link looks like an afterthought. A blog post with six contextual links to related guides, a presence in the sitemap, and five sibling articles in the same section looks like part of a deep knowledge base. Google AI Overviews inherits Google's understanding of site architecture. Pages with strong internal linking, sitemap presence, and topical clustering rank higher in traditional search and carry that authority into AI-generated answers. Topical clusters -- groups of related content under a shared URL path like /blog/ or /guides/ -- signal deep expertise in a subject area. When AI engines see that a site has published extensively on a topic, they treat the entire cluster as more authoritative. A single page on "API security" is less convincing than a site with fifteen articles under /guides/security/.

How We Score It

Six dimensions are evaluated, each contributing to a 10-point total. Internal linking is the largest component at up to 3 points. Five or more unique internal link targets on the page earns full marks; two to four earns 2 points; one earns 1 point. Sitemap discoverability contributes up to 2 points: your URL must appear in the XML sitemap for full credit. Topical cluster strength is worth up to 2 points: the URL path section should have five or more sibling pages in the sitemap. Anchor text quality contributes 1 point. Internal links should use descriptive text, not generic phrases like "click here" or "read more." Navigation connectivity adds 1 point if the page links to at least one key navigation page such as home, about, blog, or pricing. The orphan penalty costs 1 point if a page is missing from the sitemap and has fewer than three internal link targets.

How to Improve

  • 1

    Add contextual internal links to at least five other pages

    Link to related articles, category pages, and supporting content from within your body text. Each unique internal link target contributes to your score. Five or more unique targets earns the full 3 points for internal linking.

  • 2

    Ensure your page appears in your XML sitemap

    If you have a sitemap but your page is missing from it, you lose 2 points for sitemap discoverability and may be flagged as an orphan page. Add the URL to your sitemap and regenerate it after publishing new content.

  • 3

    Build topical depth with five or more sibling pages

    Create related content in the same URL path. Five or more articles under /blog/ or /guides/ earns the full 2 points for topical cluster strength. AI engines treat clusters of related content as a signal of deep expertise on that subject.

  • 4

    Replace generic anchor text with descriptive phrases

    Change "click here," "read more," and "learn more" to text that describes the target page's topic. "See our complete guide to API authentication" is descriptive. Over 50% generic anchors drops your anchor text quality to poor, costing you a full point.

  • 5

    Add navigation links to key site pages

    Link to at least one key navigation page -- home, about, contact, blog, products, services, pricing, help, or docs -- from the analyzed page. Footer navigation or breadcrumbs are the simplest way to earn this point.

Frequently Asked Questions

What if I do not have an XML sitemap?

You lose 2 points for sitemap discoverability, 2 points for topical cluster strength (which depends on sitemap data), and potentially 1 point for orphan status. Creating a sitemap can recover up to 5 points. Most CMS platforms generate sitemaps automatically.

How does the analyzer detect topical clusters?

It groups all sitemap URLs by their first URL path segment. If your page is at /blog/my-post, it counts how many other URLs in the sitemap start with /blog/. Five or more sibling pages earns the full 2 points for cluster strength.

Does the number of external links affect this score?

Not directly. However, if less than 30% of your total links are internal, the analyzer recommends adding more internal links. Excessive external linking without corresponding internal links suggests your page sends users away rather than deeper into your site.
