Why Your AEO Score Is Low: Common Causes and Fixes
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.
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
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Problem: Content is significantly out of date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:
