Why Your AEO Score Is Low: Common Causes and Fixes

Aug 18, 20258 min read

A diagnostic guide to low AEO scores. Most sites fail the same handful of signals. Here's how to identify which ones are dragging your score down and what to fix first.

The most common causes of low AEO scores

After analyzing thousands of sites, the same issues appear repeatedly. A low AEO score is rarely caused by one critical failure — it's usually several medium-severity issues across multiple pillars that compound into a score that keeps you out of AI citation consideration.

The good news: the most common issues are fixable in days, not months. Schema markup, structural updates, and metadata changes are technical tasks that don't require lengthy content production cycles.

IssueFrequencyScore impact
No FAQPage Schema73% of low-scoring sites–12 to –18 pts
No Organization Schema68%–8 to –15 pts
Dense paragraph structure (no lists)61%–10 to –15 pts
No author attribution or Person Schema58%–8 to –12 pts
No Article Schema with dateModified52%–6 to –10 pts
Title tags not matching query intent47%–5 to –8 pts
AI crawlers blocked in robots.txt23%–20 to –30 pts

Structure signal failures

Structure problems are the most common cause of low scores in the 30–50 range. They look like good content but aren't extractable:

Problem: No H2 hierarchy

Fix: Add H2 sections for each major topic. Each H2 should answer a distinct question.

Problem: Multiple H1 tags

Fix: Reduce to a single H1 that represents the page's primary topic.

Problem: All content in dense paragraphs

Fix: Convert 2-3 paragraphs per section into bullet lists or numbered steps.

Problem: H2s are statements, not questions

Fix: Rewrite H2s as question-format headings: 'What is X', 'How to Y', 'When to Z'.

Schema markup failures

Invalid Schema is worse than no Schema

Malformed or invalid Schema markup can actively harm your AEO score. AI crawlers detect validation errors and may downrank the entire page. Always validate Schema with Google's Rich Results Test before deploying.

Problem: No Organization Schema anywhere on site

Fix: Add Organization Schema to every page via a sitewide template (footer or head).

Problem: FAQPage Schema missing

Fix: Add a FAQ section to key pages and mark it up with FAQPage Schema. Minimum 3 Q&A pairs.

Problem: Article Schema missing dateModified

Fix: Add dateModified to Article Schema and update it when you update the content.

Problem: Schema present but invalid

Fix: Run every page through Google's Rich Results Test. Fix all validation errors before moving on.

Content quality failures

Problem: No direct answer in first paragraph

Fix: Rewrite the opening of each section to answer the question directly in the first 1-2 sentences, then provide context.

Problem: Content is significantly out of date

Fix: Update statistics, examples, and references. Update dateModified in Article Schema. AI platforms strongly prefer fresh content.

Problem: Key terms not defined

Fix: Add an explicit definition paragraph for your page's primary topic. AI uses these for definition query extraction.

Problem: Content is under 300 words

Fix: Expand thin content. Pages under 300 words rarely have enough context for AI to extract reliable answers.

Crawlability failures

Crawlability failures cause catastrophically low scores because AI platforms can't access your content at all. Check these first if your score is below 20:

!Check robots.txt — are GPTBot, PerplexityBot, ClaudeBot, and Google-Extended allowed?
!Check if key content is rendered via JavaScript — many AI crawlers don't execute JS
!Verify your sitemap includes all key pages and is submitted to Bing Webmaster Tools
!Check for noindex meta tags on pages you want cited

The diagnostic process: where to start

1Run a full AEO audit to see which pillar scores lowest
2Check robots.txt for AI crawler blocks — fix any blocks immediately
3Validate existing Schema with Rich Results Test — fix all errors
4If Citation Patterns score < 40: add FAQPage + Organization Schema
5If Structure score < 40: add H2 hierarchy and convert paragraphs to lists
6If Content score < 40: update dateModified and add answer-first structure
