One click, three scores

Every page, scored the way it will actually be judged

Vantage returns an SEO score, a GEO score, and a Vantage composite, each on a 0 to 100 scale. The composite is the single number that tells you where a page really stands.

The GEO difference

Score how ready your page is for AI answer engines

Most SEO extensions still only measure classic ranking signals. Vantage also scores how well ChatGPT, Claude, Gemini, and Perplexity can extract and cite your content, with three dedicated sub-scores.

GEO score = 35% Extractability + 40% Specificity + 25% Authority. Specificity is weighted heaviest because statistics and citations are what AI engines quote.

GEO Readiness

Extractability35% of score78
Specificity40% of score64
Authority25% of score81

These signals are suggestions, not requirements. Foundational SEO is the backbone of GEO, and not every checkpoint makes sense for every page.

Audit in action

A prioritized action plan, not just a number

Every check comes back with a pass, warn, or fail status and a plain explanation of why it matters and what to fix first.

The Skyfield 2026 Playbook

Built on a documented methodology, not guesswork

Vantage audits against the exact playbook Skyfield Digital uses for client work: 77 weighted rules across 10 categories, spanning technical SEO, on-page, schema, and GEO-specific structure, specificity, and authority signals. Every rule carries a severity level and a plain-language fix, so the tool and the agency methodology are the same thing.

Private by design

Your data never leaves your device

Every check runs locally, on the tab you’re viewing, and only when you click. Vantage reads the page, never changes it, and keeps the results in your browser’s own storage. There’s no sign-up, nothing running in the background, and nothing sent to us or anyone else.

FAQ

Good questions, straight answers

What is GEO? +
GEO stands for Generative Engine Optimization: how well AI answer engines like ChatGPT, Claude, Gemini, and Perplexity can extract, understand, and cite your content. Vantage scores it with three sub-scores (Extractability, Specificity, and Authority) alongside your classic SEO score.
Is Vantage really free? +
Yes. Vantage is free to install and use on both Chrome and Firefox. It is the same tool our own team uses on client work every day.
Does it collect or send my data anywhere? +
No. All page analysis runs locally in your browser and results are stored only in local browser storage. There is no account, no background tracking, and nothing is transmitted off your device.
What does the audit actually check? +
77 weighted rules across 10 categories: on-page, technical, schema, GEO structure, E-E-A-T, performance, URL, GEO specificity, internal links, and GEO authority. Rules are severity-weighted (11 critical, 42 warning, 24 info) and only fire on the page types they apply to.
Which browsers are supported? +
Chrome (and Chromium browsers) via the Chrome Web Store, and Firefox 142 and newer via Firefox Add-ons.
Does it replace my other SEO extensions? +
For most workflows, yes. Vantage combines a classic SEO audit, headings map, schema generator, social previews, full-page screenshot editor, device simulator, color picker, user-agent switcher, and keyword density tools in one place, then adds GEO scoring that single-purpose tools do not offer.
