This is not a toy “meta checker.” We bundle a large share of on-page technical SEO signals you would expect in a serious audit — meta and heading structure, canonical and schema, content volume, images and outbound links — on the page you are viewing. Content, social previews, image and link health, structured data, keyword-deep technical analysis, and competitor comparison live in the same extension.
Completely free and unlimited.
Modules
Each block pairs a real UI screenshot with a summary of what that module analyzes (zigzag layout). Every check runs on the active page.
Length and quality checks for title and meta description; missing, single, or multiple H1 warnings; canonical presence and match with the URL; content volume; Open Graph summary; schema types on the page; images without alt text; live technical SEO score and prioritized fixes. We pack the main on-page technical signals you would expect in a real audit — far beyond a quick title glance.
H1–H6 hierarchy, duplication, and structural consistency; keyword density and in-text distribution when you set a target term; date signals for freshness; alignment with canonical; readability and content-quality hints. See how both search engines and users “read” the page.
Completeness of Open Graph (og:title, og:description, og:image, og:url, og:type) and Twitter/X card tags; warnings for weak or missing fields; preview quality for social and messaging. Validate how the page will look when shared.
Full image list; file size and weight; missing alt text and SEO risk; broken assets; heavy or suspicious files from a performance angle. Combine image SEO with page weight in one view.
Complete outbound link inventory; dofollow vs nofollow split; target URL patterns; HTTP status codes and broken or risky links. Scan internal and external link health in one screen.
Parsed JSON-LD; detected schema types; hints for missing or inconsistent fields; technical view geared toward search and rich results. Inspect structured data at type and field level, not just “on/off.”
For your target keyword: deep, rule-based checks across title, meta, opening copy, H1–H6, natural density, schema sufficiency, canonical, content length, alt usage, and Open Graph completeness. Each signal explains why it matters, what to fix, and links into the right analysis view — technical SEO aligned with the keyword.
Compare your page with a competitor URL side by side: titles, descriptions, canonicals, content length, H1 structure, alt quality, Open Graph, schema, and keyword-based technical signals for both sides. Surfaces where they win and you lag, with a prioritized “what to do next” list.
