SEO Checker Extension

SEO Checker is an easy to use browser extension designed to help you optimize your website's SEO, page speed, and security. It efficiently scans thousands of pages on your site, pinpointing issues and providing clear guidance on how to fix them.

Here's what SEO Checker checks for you:

- Page Titles & Meta Descriptions: It scans your site's page titles and meta descriptions to identify those that are too long, too short, missing, or duplicated, helping you optimize these critical elements.

- Page Headings: It checks if each page has a unique and properly optimized H1 heading.

- URLs: It ensures your website's URLs follow best practices, making them easy to read and SEO-friendly.

- Content Analysis: It looks for duplicate or thin content, checks if images have proper meta tags, and assesses how well your content works on mobile devices.

- Broken Links: It identifies broken links (404 errors) and server issues that could harm your site's user experience.

- Redirect Audit: It finds and reviews temporary and permanent redirects, and detects redirect chains and loops that can affect your site's performance.

- Robots.txt Review: It verifies if a Robots.txt file is present and whether it properly specifies sitemap locations.

- Code Validation: It checks the validity of your HTML, CSS, and JavaScript, ensuring clean and efficient code.

- Page Size: It evaluates if compression and minification techniques are being used to optimize page loading speed.

- Resource Analysis: It examines resource files like CSS and JavaScript for best practices.

- Caching: It checks if caching is set up correctly to enhance site speed and performance.

- Encryption: It ensures all pages, resources, and links use HTTPS & HSTS for secure connections.

- Security Checks: It scans for common security issues, including content sniffing prevention, iframe restrictions, XSS, and clickjacking protection.
