Browser Extension
Fast, private SEO data in your browser.
Shumway SEO Toolkit gives SEOs, product managers, content teams, and developers a local workspace for inspecting the current page: metadata, headings, links, images, schema, robots rules, social previews, styles, accessibility signals, SERP previews, and export-ready data. Export CSV, TSV, JSON, or Markdown so page data is easy to move into the SEO tools, reports, and workflows you already use.
Choose Your Browser

What It Does
On-page SEO data
Review titles, descriptions, canonicals, robots directives, H1s, language, source-vs-rendered differences, query parameters, and local review issues.
Inventory pages quickly
Inspect headings, links, images, structured data, Open Graph, X/Twitter tags, fonts, colors, CSS variables, and rendered accessibility nodes.
Robots and crawler access
Test robots.txt behavior for core search crawlers, AI search bots, AI training crawlers, user-retrieval bots, and site-specific agents.
Schema and previews
Review JSON-LD, Microdata, RDFa, Google rich-result signals, social previews, and editable desktop/mobile SERP snippets.
Export-ready data
Copy fields or download CSV, TSV, JSON, Markdown, spreadsheet files, SERP images, and page image files from your current browser session.
Colorblind-friendly review
Optional accessible color palette uses clearer blue, yellow, plum, and neutral states so issue severity is not communicated by red/green alone.
Private By Design
Page data is read locally from the active tab only when you use the extension. There are no accounts, analytics, tracking pixels, remote logging, advertising identifiers, background crawling, or server-side page-data uploads.
External lookup buttons open third-party services only when you click them. Exports are generated locally and saved only when you choose to download them. Read the privacy policy for the full data-handling details.
Built For Working Reviews
Full workspace
Open the full overlay workspace for deeper review, sorting, previews, tools, and exports.
Webmaster shortcuts
Jump to Search Console, Bing Webmaster Tools, Ahrefs, Moz, Semrush, Similarweb, Archive.org, Schema Validator, and Rich Results Test.
Search and reporting helpers
Export visible search results, copy search queries, highlight nofollow links, and add percent-change chips to supported webmaster comparison views.
