Five precision instruments
for one stubborn job_
Each tool here is wired into the same engine that powers VectraSEO's 44-check audit and continuous monitoring. Use one for a single page, or run the whole battery against your site.
VectraSEO ships five free, no-signup SEO and AEO tools that share the same engine as the paid product: an AI Visibility Checker (12 AEO rules), a Schema Markup Generator (Article, Product, FAQ, LocalBusiness JSON-LD), a Robots.txt Tester (9 deterministic checks), a Meta Description Generator, and a Title Tag Generator. Use one for a single page, or run the full 54-check audit on your whole sitemap. Nothing is stored, no card required.
