Description

Instantly check any page's title, meta tags, headings, Open Graph data, and other on-page SEO signals — no login, no tracking. See a page's on-page SEO signals in one click — no account, no tracking, no data leaves your browser. SEO On-Page Inspector reads what's already in the page and shows you: • Title tag + character count • Meta description + character count • Canonical URL, robots meta, language, viewport • H1 / H2 headings • Open Graph and Twitter Card tags • Word count, image alt-text gaps, internal vs external link counts Everything runs locally in the active tab. The extension makes no network requests and stores no data. Built by the team at SmartLabs (https://smartlabs.co.za), South Africa's lab equipment supplier — built this because we needed a fast way to sanity-check our own product pages.
