ShipcheckShipcheck vs Detailed SEO Extension
Detailed SEO Extension is a Chrome tool for on-page SEO: titles, headings, links, and images on the tab you have open. Shipcheck checks those basics too, then answers whether ChatGPT, Perplexity, or Claude can cite the URL, and what the server HTML actually contains.
