On-page SEO checker: overview, content, links, hreflangs, images, structured data, speed, and monitoring. Advanced SEO Checker is a powerful, free Chrome browser extension designed for comprehensive on-page SEO analysis. It allows you to instantly audit any webpage you're visiting, providing detailed insights across multiple critical SEO areas without leaving your browser. When you click the extension icon on a page, it opens a popup with organized tabs that break down the page's SEO health, helping you spot issues and opportunities quickly. Key Features and What It Does Overview Tab: Quickly review essential metadata like title tags, meta descriptions, Open Graph tags (for social sharing), robots directives, and canonical URLs. This ensures search engines and social platforms understand and display your page correctly. Content Tab: Analyze word count, readability scores, heading structure (H1-H6), and keyword density. It helps you create high-quality, user-friendly content that ranks better by avoiding keyword stuffing or thin content. Links Tab: Check internal and external links, including status codes, dofollow/nofollow attributes, and anchor text. Identify broken links or poor linking practices that could hurt user experience and SEO. Hreflangs Tab: Verify hreflang tags for multilingual or multi-regional sites, ensuring search engines serve the right version of your page to users in different languages or locations. Images Tab: Scan for missing alt text, oversized images, or broken images. Proper image optimization improves accessibility, page speed, and image search rankings. Structured Data Tab: Inspect JSON-LD, microdata, or other schema markup to confirm rich snippets (like stars in search results) are set up correctly. Speed Monitoring: Integrate with PageSpeed Insights to check loading times and performance scores, plus track changes over time. Issues Detection & Monitoring: Highlight real-time problems, compare against baselines, and monitor SEO metrics historically using Chrome storage. The extension runs a content script on pages you visit, collects data securely (with permissions for all URLs and storage), and displays everything in an easy-to-use popup interface.
