It is a long-established fact that a reader will be distracted by the readable content of a page when looking.

One browser extension audits any page for classic SEO and GEO (Generative Engine Optimization) in a single click. 77 weighted checks, three scores, a prioritized action plan, and a full toolkit. Everything runs locally.
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.
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.

PerplexityThese signals are suggestions, not requirements. Foundational SEO is the backbone of GEO, and not every checkpoint makes sense for every page.
Every check comes back with a pass, warn, or fail status and a plain explanation of why it matters and what to fix first.

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.
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.
Install in one click. Audit your first page in the next thirty seconds.
