On-page SEO check

What it reads

This measures ONE page, from the HTML you pasted, and nothing else.

• Title tag (30–60 chars) 10 of 100
• Meta description (110–160 chars) 10 of 100
• Exactly one <h1> 9 of 100
• html lang attribute 6 of 100
• Mobile viewport meta 7 of 100
• Canonical link 7 of 100
• Open Graph (title/description/image) 8 of 100
• Twitter card 5 of 100
• Structured data (JSON-LD) 8 of 100
• Images have alt text 6 of 100
• Not blocked by robots noindex 7 of 100
• Content in the HTML (not a blank SPA shell) 5 of 100
• Page address carries the page keyword 5 of 100
• Language alternates (hreflang) are valid, self-referencing and have x-default 3 of 100
• LocalBusiness structured data with name, address and telephone 4 of 100
• Whether a buyer could find what you sell from this page — a page or link named for pricing or products, an Offer in the structured data, and something to click to buy or ask. Reported beside the score, never inside it

What it does not look at

• whether the page is actually indexed, or where it ranks for anything — that is off-page and needs a live search source
• your other pages, your internal links, or your sitemap as a whole
• whether the og:image URL resolves to a real image (the tag being present is all HTML can tell us)
• page speed, Core Web Vitals, or anything that needs the page to actually load
• whether the copy is any good, or aimed at terms anyone searches for
• whether a pricing or products page exists elsewhere on your site — the offer-surface stat below reads the ONE page you pasted, so a shop on a page you did not paste is unread here rather than absent, and the address of this page is unknown to it either way
