SEO JS Checker: Essential Tool for JavaScript SEO Audits

SEO JS Checker is a powerful Chrome add-on designed to assist users in identifying SEO issues related to JavaScript rendering. This tool efficiently compares the raw HTML of a webpage with its rendered DOM, helping users uncover discrepancies in meta tags, headings, links, and visible text caused by JavaScript. It provides a clear analysis of how dynamic content affects a webpage's SEO performance, making it invaluable for SEOs, developers, and site owners.

Key features of SEO JS Checker include the ability to analyze tags such as title, meta descriptions, and canonical links, as well as H1 and H2 headings. It also detects changes in Open Graph and Twitter tags, breaks down internal and external links, and highlights content modifications post-JavaScript execution. Users can export comprehensive reports in JSON, CSV, or human-readable TXT formats, making it a versatile tool for optimizing web content for search engines.
