SEO Page Audit

Check webpages for SEO, structure, accessibility, and technical basics.

SEO Page Audit is a simple browser extension for checking the basic structure and SEO readiness of any webpage. It helps developers, marketers, QA teams, website owners, and content teams quickly review important page elements without leaving the browser. With one click, the extension scans the current page and shows useful information such as page title, title length, meta description, heading structure, image alt attributes, links, Open Graph metadata, Twitter metadata, canonical URL, page language, viewport tag, robots tag, charset, structured data blocks, scripts, and stylesheets. The extension also includes a practical image alt text check. It highlights when images are missing alt attributes or have empty alt text, helping reviewers identify potential accessibility and search visibility issues. SEO Page Audit now includes a hreflang audit for international SEO. It detects whether hreflang tags are present, counts the alternate language or regional URLs, checks whether the page references itself, identifies whether an x-default fallback is included, and shows the actual alternate links found on the page. This makes it easier to review multilingual or multi-regional websites and quickly understand which language or regional versions are being declared. The hreflang check also helps identify common implementation issues, such as invalid language or region codes, non-absolute alternate URLs, and missing self-references. When invalid hreflang codes are found, the extension breaks them down into their language and region components so reviewers can see exactly which part is valid and which part needs attention. SEO Page Audit is useful when reviewing landing pages, company websites, ecommerce pages, blogs, documentation pages, multilingual websites, regional websites, and any webpage where basic SEO and structure matter. The extension runs locally in your browser. It does not require an account and does not send page data to external servers. SEO Page Audit is designed to be lightweight, practical, and easy to use. It is not a replacement for a complete SEO platform, crawler, hreflang monitoring system, or performance audit tool. Instead, it gives you a quick first-pass review of the current page directly from the browser.
