Direct Answer Clarity (25% Weight)
This is the most heavily weighted metric because it measures the single most important AEO factor: whether your content leads with a clear, concise answer that AI systems can extract. Answer engines scan the first 1-2 sentences after a heading to find extractable answers. Pages that bury the answer below introduction paragraphs, disclaimers, or filler content get skipped.
A perfect score means every page on your site opens with a 40-60 word direct answer immediately after the main heading. The answer uses clear, factual language with no hedging, no "it depends," and no filler. AI systems can extract this answer and present it directly to users without modification.
Heading Structure (20% Weight)
Heading hierarchy tells AI systems how your content is organized and what each section covers. A clean H1, H2, H3 structure functions like a table of contents that answer engines use to navigate your page and extract the right section for a given query. Disorganized headings — skipping levels, using multiple H1s, or using headings purely for visual styling — confuse AI parsers.
The ideal structure uses one H1 per page (the page topic), H2s for each major subtopic (ideally phrased as questions), and H3s for supporting details within each subtopic. This mirrors how users think about a topic and how AI systems structure their understanding of your content.
FAQ Density (20% Weight)
FAQ density measures how many structured question-and-answer pairs exist across your site with proper FAQ schema markup. FAQ schema is the highest-impact structured data for AEO beginners because it directly signals to search engines that your content contains answers to specific questions. Sites with 10+ FAQ pairs have significantly higher snippet capture rates.
FAQ density is not just about quantity. Each FAQ pair should answer a real question your audience asks, be formatted as a concise 50-100 word answer, and include FAQ schema markup. Low FAQ density means fewer entry points for AI systems to discover and surface your content in response to user queries.
Snippet Readiness (20% Weight)
Snippet readiness evaluates whether your content is formatted in the specific structures that trigger featured snippet selection: 40-60 word paragraph answers for definition queries, numbered lists for how-to queries, and comparison tables for versus queries. Content that is well-written but poorly formatted for snippets will lose to competitors whose content matches the snippet format exactly.
Full snippet readiness means your definition pages use the "X is [category] that [differentiator]" pattern, your process pages use numbered step lists, and your comparison pages include structured tables with clear column headers. Each format targets a different snippet type, maximizing your coverage across query categories.
AI Readability (15% Weight)
AI readability measures how easily large language models and AI search engines can parse, understand, and summarize your content. High AI readability means your writing uses clear, factual sentences with consistent entity references, specific data points, and no ambiguous language. Low AI readability comes from jargon-heavy writing, excessive metaphors, vague phrasing, and inconsistent terminology.
This metric has the lowest weight because it amplifies the other four. Perfect AI readability without direct answers or heading structure still produces a low score. But combined with strong fundamentals, high AI readability makes your content significantly more likely to be selected because AI systems can confidently extract and present your answers without risk of misinterpretation.
