Description
Compares raw HTML vs. rendered DOM for SEO fields and shows indexability/rendering changes in the icon. Source vs Render SEO compares the raw HTML source of a page with the rendered DOM and shows whether JavaScript changed important SEO fields such as canonical, meta robots, title, meta description, H1s, or hreflangs. What It Does Many SEO issues only become visible after JavaScript has run. This extension checks both versions of a page: - Source HTML: the raw HTML returned by the server before JavaScript execution - Rendered DOM: the final document after JavaScript has modified the page The extension then highlights differences directly in the popup and updates the toolbar icon to show the current indexability and rendering state. The toolbar icon show green, red, yellow or a combination, depending on the changes.
