Every tool on this page ships a Chrome, Firefox or other browser extension, stated on its own website. An extension puts SEO data where you already work: keyword metrics beside a search results page, an on-page check of the page you are viewing, backlink counts for a domain, or a content score inside a document editor.
Extensions often come from a larger platform and may need an account or a paid plan to show full data, so check the extension's store page and the vendor's own site for what it shows without one. An extension also reads the pages you visit; look at the permissions it asks for before you add it. The cards are ordered by the number of published guides that name each tool.
