Your SuperSchema Score is your site’s AI-visibility grade: a single number from 0 to 100 that reflects how well AI systems like ChatGPT, Perplexity, and Google’s AI overviews can find, read, and trust your pages. It comes from a Site Scan, it carries a letter grade and a plain-language band, and it updates as you improve your site. It is not one opinion about one page; it is a weighted blend of five categories, each measuring a different part of how machines read your content.
The five categories and their weights #
Every scan produces a score for each of five categories, then rolls them into your overall SuperSchema Score using the weights below. In the report this section is labeled "Category Breakdown", and hovering any category card reveals exactly what SuperSchema checked.
| Category | Weight | What it measures |
|---|---|---|
| Access | 15% | Whether AI crawlers can reach your content at all. |
| Content | 25% | Whether there is substantial, well-written content to learn from. |
| Structure | 15% | Whether your HTML hierarchy is clean and easy to follow. |
| Schema | 25% | Whether JSON-LD structured data gives AI explicit context. |
| Alternate | 20% | Whether AI-readable versions of your pages exist and are reachable. |
What each category checks #
- Access (AI Crawler Access)
- Checks that robots.txt allows AI bots, that nothing is blocking pages with noindex, and that pages load without JavaScript. If AI cannot reach or render a page, nothing else matters.
- Content (Content Quality)
- Checks that word count is over 300, that the text-to-HTML ratio is healthy, and that paragraphs are meaningful. AI needs real, substantial content it can actually learn from and cite.
- Structure (Page Structure)
- Checks for a proper H1 heading, a logical heading order, and lists and tables for data. Clean structure helps AI understand your content hierarchy.
- Schema (Schema Markup)
- Checks that valid JSON-LD is present, that the schema types are relevant to the page, and that required fields are complete. This is the explicit context that tells AI what a page is.
- Alternate (Alternate Formats)
- Checks that a Markdown version is available, that a plain-text alternative exists, and that those files are accessible. Clean alternate formats make your content instantly AI-readable.
Score bands #
Where your overall score lands maps to a plain-language band. The same bands apply to each individual category card, so you can spot a weak category at a glance.
- 96 to 100 · Super
- AI systems have a strong read on your site. You are in rare company.
- 80 to 95 · Good
- A strong foundation with a few clear gaps to close.
- 60 to 79 · Fair
- AI can understand parts of your site, but the signal is uneven.
- 40 to 59 · Needs Work
- AI systems are likely missing important context.
- 0 to 39 · Critical
- Major gaps are keeping AI from understanding your site.
Letter grades #
Alongside the number, the report shows a letter grade badge with a label. It is a finer-grained view of the same score.
| Score | Grade | Label |
|---|---|---|
| 97 to 100 | A+ | Elite |
| 93 to 96 | A | Excellent |
| 90 to 92 | A- | Great |
| 87 to 89 | B+ | Good |
| 83 to 86 | B | Above Average |
| 80 to 82 | B- | Fair |
| 77 to 79 | C+ | Needs Work |
| 73 to 76 | C | Below Average |
| 70 to 72 | C- | Poor |
| 60 to 69 | D | Critical Issues |
| 0 to 59 | F | Major Problems |
How to improve it #
- Find your lowest category. The report highlights it under "Recommended next move" and in the "Focus" stat at the top.
- Fix Access first if it is low. A blocked or JavaScript-only page drags everything down, because AI cannot read the rest.
- Add or improve Schema on your most important pages. Generating valid, relevant JSON-LD with SuperSchema directly raises the Schema category.
- Publish AI-readable files. Hosting Markdown and plain-text versions of your pages raises the Alternate category.
- Strengthen Content and Structure. Add substantial copy, a clean H1, logical headings, and lists or tables where they fit.
- Re-scan to see the new score and confirm the gain.
