AIO Score
AIO Score: the metric that reveals whether your site is ready to be cited by AIs
A 0-to-100 rating calculated across 4 dimensions — crawlability, structured data, content citability, and entity authority. Knowing where you are is the first step to appearing in ChatGPT, Perplexity, and Google AI Overview responses.

The AIO Score was developed by FRT Digital to quantify what was previously subjective: how ready a site is to be extracted and cited by language models. The metric evaluates 4 dimensions with different weights — because not every criterion has the same impact on citation probability.
The 12 criteria in 2 pillars
Technical — Crawlability and Rendering
The two most impactful criteria of the Technical Score.
Crawlability: verifies that BingBot, GPTBot, and PerplexityBot are allowed in robots.txt.
Rendering: verifies that critical pages deliver content in HTML without depending on JavaScript — required for simpler AI bots to index content.
Technical — Schema, llms.txt and Performance
Root entity Schema: Organization or LocalBusiness with name, url, sameAs — defines company identity for AI models.
llms.txt: file at the domain root that instructs AI models about the site's content.
Schema coverage by page type: Article, FAQPage, and Service on critical pages.
Core Web Vitals: mobile LCP at the 75th percentile.
Content Score (C7+C8) — E-E-A-T and Citability
The two highest-weight criteria of the Content Score.
E-E-A-T: % of critical pages with experience, expertise, authority, and trustworthiness demonstrated.
Citability: % of pages with direct openings and key paragraphs that can be extracted in isolation by a language model.
Content Score (C9–C12) — Depth, Freshness and Structure
Topical depth: % of the segment's main intents covered by the site with a dedicated page.
Freshness: % of critical content updated in the last 12 months.
Structure for direct extraction: pages with FAQ, lists, or tables produce cleaner chunks for RAG.
Internal linking.
How to interpret the AIO Score
0 – 30: critical
Active blockers. The site is invisible or inaccessible to AIs — usually C1 (crawlability) at zero or all critical pages in pure CSR. Immediate action on robots.txt and rendering before any other effort.
31 – 55: developing
Partial technical foundation. Content without citability optimization — vague openings, no verifiable data, no structured FAQ. Site crawled, but content not extracted as a source by models. Appears occasionally, not consistently.
56 – 70: in progress
Reasonable technical structure. Relevant gaps in E-E-A-T or citability — site indexed and crawled, but loses to competitors with content more optimized for extraction. Focus on improving C7 (E-E-A-T) and C8 (citability) to rise consistently.
71 – 85: good
Site being cited consistently in relevant queries. Specific improvement points — usually topical depth (C9) and freshness (C10). Focus on scaling content volume in priority clusters and expanding Schema coverage.
86 – 100: reference
High citability. Consolidated topical authority in the segment. A score rarely achieved from the start — it's the result of months of consistent implementation. Companies in this range have a presence that's hard for competitors to contest in the short term.
Why the AIO Score matters
Before the AIO Score, companies tried to appear in AIs without knowing where they stood. They invested in content with unresolved technical blockers, implemented Schema.org partially, or built entity authority without a crawlability foundation. The score makes visible what was invisible — and transforms AIO from intuition into a measurable process.

Frequently asked questions
How is the AIO Score calculated?
The AIO Score combines Technical Score (40% weight) and Content Score (60% weight), each with 6 criteria. Formula: AIO Score = (Technical Score × 0.40) + (Content Score × 0.60). Technical Score = weighted sum of C1 to C6; Content Score = weighted sum of C7 to C12. Two criteria act as blockers: C1 = 0 caps the total score at 50; C2 = 0 caps it at 60.
What is the difference between the AIO Score and the free analysis tool?
The free analysis tool on the audit page performs a quick evaluation of technical and content criteria for your URL. The full AIO Score is part of an audit conducted by FRT's team, which analyzes a larger sample of pages, tests real AI visibility, and includes competitor analysis. The tool delivers an initial diagnosis; the full AIO Score delivers the complete map.
How often should the AIO Score be recalculated?
The score is recalculated whenever there are significant implementations — such as adding Schema.org, publishing a batch of articles, or acquiring relevant external mentions. In active AIO projects, the score is updated quarterly as an evolution baseline. Monthly citation monitoring complements the score with real result data.
Does a high AIO Score guarantee citations in AIs?
A high score means the infrastructure is ready — it is not an automatic guarantee of citation. Citation also depends on the volume and quality of published content, topic competitiveness, and how frequently AIs index updates. The score measures readiness; citation is the result of readiness plus relevant content for the tested queries.
Is the AIO Score an industry standard or a proprietary framework?
It is a proprietary framework by FRT Digital, developed from the analysis of criteria that the main generative AIs use to select sources. There is no universal AIO score standard in the market yet — the concept is recent and each specialized company develops its own diagnostic methodology.
Does the AIO Score measure presence in Google AI Overview?
Yes. The crawlability dimension includes verification of Googlebot indexing in addition to BingBot, and the structured data dimension evaluates FAQPage and Article — markups that are decisive for appearing in Google AI Overview. Sites with a high score have the technical foundation to appear in both ChatGPT/Copilot (via Bing) and Google AI Overview.
