SEO Quick Check EN

SEO Quick Check is a fast, private, local on-page SEO analyzer for website owners, SEO professionals, developers, bloggers, marketers and content creators.

Analyze the webpage you are viewing with one click. The extension reads the current page DOM in your browser and gives you a clear SEO Health Score with practical checks and concise recommendations. No account, sign-up, cloud service or external SEO API is required.

What you can check:
• Page title and meta description, including character counts and copy buttons.
• Current URL, HTTPS, URL length, query parameters and hash.
• Canonical URL and robots or googlebot meta directives.
• H1-H6 counts, empty headings, skipped levels and a readable heading outline.
• Images, missing ALT attributes, empty ALT values, lazy loading and image formats.
• Internal and external links, anchor links, email and telephone links, invalid or empty destinations, nofollow, sponsored and UGC attributes.
• Open Graph and Twitter or X Card metadata for social sharing previews.
• Hreflang annotations, duplicate language codes, incomplete entries and x-default.
• JSON-LD structured data detection, parsing and schema type discovery.
• HTML language, viewport, charset, favicon, manifest, AMP and pagination links.
• Estimated visible word count, excluding navigation, scripts, styles and hidden text.

The report is organized into Overview, Content, Links, Images, Social and Technical sections. Use Refresh to analyze dynamic pages again, Search checks to find a specific issue, and Copy report to export a plain-text summary.

The interface follows your browser language by default and supports English and Simplified Chinese. You can choose a language manually and reset it to Browser default.

Privacy first: analysis runs locally in your browser. The extension does not upload webpage content, URLs, browsing history or SEO reports. It does not crawl websites, request external links, download page images, use analytics or execute remote code. Only the page you actively choose to inspect is analyzed.

SEO Quick Check provides a heuristic health score based on common on-page SEO practices. It is not a Google ranking score and does not predict rankings, indexing or traffic. Optional features such as hreflang, Twitter Cards and structured data are reported with context rather than treated as universal requirements.
