Web Quality factor
This factor is part of Web Quality — the weighted 0..100 score that sits above Web Standards. Its weight depends on what kind of site is being measured. Web Standards items take priority; this factor only enters the score once Web Standards passes.
- Base weight
- 0.5 applied to every site type unless overridden below
- Why this weight
- JSON-LD richness — how completely the site describes itself for LLMs. Maps to citizenship for content sites.
Per-site-type overrides
| Site type | Weight | Δ vs base |
|---|---|---|
| E-commerce | 0.8 | +0.3 |
| News / Publisher | 1.0 | +0.5 |
| Personal site | 0.2 | -0.3 |
| Education | 0.8 | +0.3 |
| Government | 0.8 | +0.3 |
| Media / Streaming | 0.8 | +0.3 |
Site types not listed inherit the base weight.
What this means for your business
When ChatGPT or Perplexity describes your business, they're pulling from the structured details on your site. The thinner those details, the more the AI guesses — and the more often it gets your hours, prices, or services wrong.
Plain title: How well your site feeds AI the right facts
What we measure
AI tools parse JSON-LD to understand your business. The more complete your structured data, the more accurately AI assistants describe you when someone asks.
How to improve your score
Add complete `LocalBusiness` or `Organization` schema with every available field — name, address, phone, openingHours, employees, areaServed, sameAs, priceRange, and so on.

Implementation notes
Score each JSON-LD block by field-completeness against the schema.org type definition for its `@type`.
Scoring
Scoring formulas are versioned with the methodology. The current method (v1.2.0) maps raw measurements to pass, warn, fail. Factor weights determine how much each contributes to the composite — see the methodology index for the full table.
