AI search referrals up 527% YoY · convert 4.4× better than organic

Score, diagnose, and engineer your way into AI-generated answers.

AuthoritySignal is a Generative Engine Optimization agency. We measure exactly how ChatGPT, Claude, Perplexity, Google AI Overviews, Gemini, and Bing Copilot see your brand — then build and execute a prioritized plan to make you the default citation.

Your SEO stack doesn't measure AI citability

Keyword density, backlink profiles, and DA scores don't predict whether ChatGPT will quote your page. AI engines rank differently — brand mentions carry 3× the weight of backlinks, and only 11% of domains rank in both ChatGPT and Google AI Overviews. If you're not measuring GEO, you're flying blind on the fastest-growing traffic channel on the internet.

A composite GEO Score from six weighted signals

Every audit produces a transparent 0–100 score across six categories. No black-box ranking. You see the formula, the weights, and exactly what to fix first.

01 · AI Citability

Are you quotable?

We score every content block on five dimensions — Answer Block Quality, Self-Containment, Structural Readability, Statistical Density, and Uniqueness — targeting the 134–167-word answer-first format AI engines prefer.

Weight
25%
02 · Brand Authority

Do AIs know you?

We scan your presence across the platforms AIs actually cite — YouTube (25%), Reddit (25%), Wikipedia (20%), LinkedIn (15%), plus Quora, Stack Overflow, GitHub, Hacker News, podcasts, and news — and produce a Brand Authority Score.

Weight
20%
03 · E-E-A-T

Can you be trusted?

A 25-point rubric per dimension quantifies Experience, Expertise, Authoritativeness, and Trustworthiness. We enforce word-count benchmarks and Flesch Reading Ease 60–70 for content that both humans and models rank highly.

Weight
20%
04 · Technical

Can crawlers read you?

Eight-category technical audit — crawlability, indexability, security, URL structure, mobile, performance, Core Web Vitals, and SSR. Extra emphasis on JS-rendered content detection, because AI crawlers have limited JavaScript execution.

Weight
15%
05 · Schema.org

Are your entities linked?

We detect, validate, and generate JSON-LD across the types that move the needle — Organization, LocalBusiness, Article+Author, Product, FAQPage, SoftwareApplication, WebSite+SearchAction, Person — and emit a sameAs linking strategy across platforms.

Weight
10%
06 · Platform

Each engine, ranked.

Only 11% of domains rank across both ChatGPT and Google AI Overviews. We score you separately for AI Overviews, ChatGPT, Perplexity, Gemini, and Bing Copilot — each with its own ranking-factor checklist — so you optimize for the surfaces that matter to your buyers.

14 audit dimensions. Five parallel engines. One GEO Score.

Launch a full audit and our platform fires five specialized engines in parallel — AI visibility, platform analysis, technical infrastructure, content quality, and schema markup. Each engine runs deep analysis across citability, crawler access, llms.txt compliance, brand authority, structured data, and nine more dimensions. Results aggregate into a single composite score with a prioritized, agency-grade action plan.

Frequently asked

About GEO, scoring, crawlers, llms.txt, and how AuthoritySignal works.

GEO stands for Generative Engine Optimization — optimizing for the paragraph an AI produces after synthesizing hundreds of sources, not for the ranked list of ten blue links Google returns. The fundamentals overlap: crawlable content, authoritative signals, topical depth. But the tactics diverge sharply.

AI engines weight brand mentions 3× more strongly than backlinks. Platforms like YouTube, Reddit, and Wikipedia outweigh traditional SERP signals. And each AI engine ranks differently — only 11% of domains rank in both ChatGPT and Google AI Overviews — so platform-specific optimization is required. Conventional SEO tools don't measure any of this.

The composite GEO Score is a weighted sum of six categories: AI Citability & Visibility (25%), Brand Authority Signals (20%), Content Quality & E-E-A-T (20%), Technical Foundations (15%), Structured Data / Schema.org (10%), and Platform Optimization (10%).

Inside Brand Authority, the sub-weights are YouTube 25%, Reddit 25%, Wikipedia 20%, LinkedIn 15%, other platforms 15%. It's a transparent formula — no black-box ranking. Every audit shows you the inputs, the weights, and the score contributions line by line.

llms.txt is an emerging standard — proposed by Jeremy Howard in September 2024 — that acts as an AI-friendly sitemap. It tells AI engines what your site is about, where the canonical content lives, and which pages to prioritize. Adoption is still early (roughly 5% of sites as of 2026), which makes it a competitive edge for brands that move now.

AuthoritySignal analyzes your existing llms.txt or generates a new one from a full site crawl. We can also produce an llms-full.txt with deeper page content for engines that want it — all included in the Standard and Premium tiers.

We check your robots.txt against a 3-tier matrix of 14+ AI crawlers:

Tier 1 (critical): GPTBot, OAI-SearchBot, ChatGPT-User, ClaudeBot, PerplexityBot. Tier 2 (important): Google-Extended, GoogleOther, Applebot-Extended, Amazonbot, FacebookBot. Tier 3 (training-only): CCBot, anthropic-ai, Bytespider, cohere-ai.

Each bot gets a per-path allow/deny status and a recommendation. Blocking a Tier 1 crawler is the single fastest way to become invisible — we catch it in the first 10 seconds of an audit.

A full GEO audit detects your business type (SaaS / Local / E-commerce / Publisher / Agency / Hybrid), crawls up to 50 pages respecting robots.txt, and launches five analysis engines in parallel: AI Visibility, Platform Analysis, Technical, Content, and Schema. Each engine evaluates multiple dimensions of your GEO readiness.

Results are aggregated into a composite GEO Score with a prioritized action plan. The output is a polished, client-ready report — available as a downloadable PDF — sized to be handed directly to a client or attached to a board deck.

Most brands see measurable GEO Score improvements within the first 30 days. Technical fixes — crawler access, schema deployment, llms.txt — take effect almost immediately. Content and brand-authority signals compound over 60–90 days as AI engines re-index and recalibrate their source rankings.

Your monthly progress report tracks every delta so you can see exactly which levers moved the number and by how much.

Book a free Quick Scan. In about sixty seconds we'll surface a homepage-level GEO snapshot — enough to know whether your robots.txt is blocking AI crawlers, whether you have schema, whether your brand mentions are visible, and roughly where your GEO score lives.

If the gaps are meaningful, we follow up with a full GEO audit and a tailored engagement recommendation. Most brands go from first scan to active optimization in under a week.
