It is a top-tier tool for getting a quick overview of a site's on-page SEO. While its JSON-LD display isn't perfect—I'd prefer a better, more readable format—it's still the only tool of its kind that provides a usable output. Its overall performance for basic SEO checks like meta tags, headings, and image attributes is outstanding, making it an excellent, must-have extension.
