AI systems reward sites that demonstrate subject-matter expertise through depth — a single 800-word explanatory post or a 500-word documentation page signals authority far more than twenty 100-word feature blurbs. Shallow marketing content places you in the "generic vendor" bucket where citations go to the competitor who has written a methodology doc, even if that competitor ships a weaker product.
High because depth indicators are the primary expertise signal AI systems use to rank sources for citation.
Publish at least one piece of substantive content meeting one of four thresholds: documentation with 500 or more words, a methodology page explaining product rationale, a step-by-step technical guide, or an 800-plus-word blog post on the product's domain. Create files under src/app/docs/ or src/content/blog/.
src/app/docs/methodology/page.tsx
src/content/blog/deep-dive.mdx
ID: geo-readiness.authority-expertise.expertise-depth
Severity: high
What to look for: Check whether the site has content that goes beyond surface-level marketing. Count the word length of the longest documentation page, the longest blog post, and any methodology page. Look for: a /docs or /guides route with 500+ words of substantive content, methodology documentation explaining the "why" behind product decisions, detailed technical guides, in-depth blog posts (800+ words) on the product's domain, or educational content that teaches the reader something.
Pass criteria: The site must have at least 1 of the following 4 depth indicators: (1) documentation with 500+ words of substantive content, (2) a methodology or "how we built this" page, (3) detailed technical guides with step-by-step instructions, or (4) in-depth blog posts (800+ words) on the product's domain. Count the word length of qualifying content to verify it meets the threshold.
Fail criteria: 0 of 4 depth indicators found. Only shallow marketing content exists — feature lists, benefit statements, and pricing with no technical depth, guides, or methodology. No documentation or educational content. Blog posts that are all under 200 words do not qualify. Report: "0 of 4 depth indicators found — longest content page is X words".
Skip (N/A) when: Never — even simple products can explain their approach and domain.
Detail on fail: "0 of 4 depth indicators found. Longest content page is 150 words. No documentation, guides, or in-depth content. AI systems see this as lacking expertise." or "Blog exists but longest post is 180 words — 0 of 4 depth indicators met (800+ words required for blog depth)".
Cross-reference: For a deeper analysis of content marketing quality, brand voice, and persuasion structure, the Marketing Content Quality audit covers this in detail.
Remediation: Depth signals expertise. Add content that demonstrates you understand your domain. Create pages under src/app/docs/ or src/app/blog/ with 500+ words of substantive content:
This content serves dual duty: it helps users AND tells AI systems you're an authoritative source.
