SEO Health Checker Extension

SEO Health Checker Extension is a free browser extension designed for on-page SEO audits and technical analysis, available for both Chrome and Firefox. It enables users to analyze any webpage quickly, identifying key SEO issues and providing actionable recommendations aimed at improving visibility and search ranking. The tool is targeted at SEO specialists, content writers, website owners, bloggers, and developers, offering immediate and comprehensive details about a website's SEO health as soon as it is enabled.

The extension consolidates multiple SEO analysis tools into a single, simple interface. Among its main features are page-by-page SEO audits, meta tag analysis with improvement recommendations, and structured data validation and extraction for JSON-LD. Users can review heading architecture through a clear H1–H6 hierarchy display, evaluate internal and external links (including nofollow tags and link authority), and assess image optimization, including checks for alt text and accessibility suggestions. The tool also scans for search engine verification meta tags from platforms such as Google, Bing, and Yandex, and highlights detected tokens.

Keyword analysis is included, allowing users to monitor keyword density, word count, and the most commonly used terms on a page. The extension scores websites based on meta tags, structured data, headings, and images, highlighting issues such as overly long titles, duplicate meta tags, and heading hierarchy problems. For each issue found, it offers specific recommendations, such as keeping titles under 70 characters or removing duplicate tags, to help boost the site's search performance.

SEO Health Checker Extension is provided free of charge and is developed by Alimam Miya. Its interface is designed to save time for SEO professionals and content writers by delivering comprehensive, actionable insights without unnecessary complexity. The extension is featured by Google and integrates technical and content-focused SEO checks into a single workflow.
