Shumway SEO Toolkit v0.1.3 docs

This page documents the screens, data surfaces, tools, exports, and privacy behavior in Shumway SEO Toolkit v0.1.3.

For release history, see the changelog.

Browser-Specific Docs

Start with your browser page if you need install instructions or API differences such as JavaScript toggling, download behavior, context-menu support, or store packaging notes.

Getting Started

1. Open the page you want to inspect.
2. Click the Shumway SEO Toolkit browser action.
3. Open the workspace from the extension action or context menu for deeper review.
4. Copy individual fields or export datasets when you need to share or archive the review.

The extension reads the active tab on demand. It is designed for normal HTTP and HTTPS pages and does not run a background crawler.

Screens

Overview Section

Overview is the triage screen. It summarizes whether the page appears indexable and lists the highest-priority local review items.

• Indexability: current URL, canonical URL, robots meta, X-Robots-Tag, and robots.txt result.
• Technical fields: viewport, language, HSTS, charset, word count, and character count.
• Metadata: title, H1, meta description, keywords, and text-length signals for preview use.
• Source vs rendered: compares source title, H1, description, canonical, and robots meta against rendered values.
• Discovery: robots.txt URL, sitemap URLs, hreflang tags, noscript count, resource hints, URL parameters, and likely faceted parameters.
• Review items: local warnings and informational checks grouped from the audit engine.

Headings

The Headings section shows the rendered H1-H6 outline in page order. It counts each heading level, supports copying individual heading text, and exports heading rows.

Review items may flag missing H1, multiple H1s, title/H1 duplication, empty headings, duplicate heading text, UI-label headings, and skipped heading levels.

Links

The Links section inventories anchors from the rendered page. It records visible anchor text, resolved URL, raw href, whether href exists, rel tokens, target, and link kind.

• Link kinds include internal, external, anchor, mailto, tel, and other.
• Sort by page order, kind, text, URL, or rel tokens in the full workspace.
• Copy and export link data as CSV, TSV, JSON, or Markdown.
• Use the context menu or Tools section to highlight nofollow, sponsored, and UGC links on the page where the browser supports that context.

Review items may flag JavaScript hrefs, empty hrefs, hash-only links, links without visible anchor text, unsafe target=_blank links, duplicate anchor text pointing to different URLs, and one URL with multiple anchor texts.

Images

The Images section shows image previews, alt text, source URLs, dimensions, loading mode, and width/height attribute coverage.

• Filter images with and without alt text.
• Sort by page order, filename, alt text, source URL, size, or loading mode in the workspace.
• Copy image URLs, export image rows, or download page image files where browser permissions allow it.
• Review image CSV/TSV/JSON/Markdown exports or image ZIP downloads locally.

Review items may flag missing alt text, priority images without alt text, missing width/height attributes, tiny images that may be decorative, and very large image dimensions.

Schema

The Schema section detects JSON-LD, Microdata, and RDFa. JSON-LD is parsed locally and shown with type, display name, parse status, source, notes, and Google rich-result style signals where available.

• Sort by page order, format, schema type, JSON name, or validity.
• Export schema as CSV, TSV, JSON, or Markdown.
• Open the current page in Schema Validator or Rich Results Test.
• Review recommended-field notes for common Article, Product, FAQPage, BreadcrumbList, Organization, WebSite, and LocalBusiness types.

Review items may flag parse errors, Google rich-result warnings or errors, missing recommended fields, duplicate schema @id values, schema URL and canonical mismatches, and breadcrumb structured-data notes.

Robots

The Robots section fetches robots.txt for the current origin, reads sitemap declarations, evaluates the current URL, and compares crawler access for search and AI-related crawlers.

• Core search crawlers include Googlebot and Bingbot.
• AI search crawlers include OAI SearchBot, Claude SearchBot, PerplexityBot, and detected site-specific bots.
• AI training crawlers include GPTBot, ClaudeBot, Google Extended, Applebot Extended, CCBot, and detected agents.
• User-retrieval crawlers include ChatGPT User, Claude User, Perplexity User, and detected agents.
• Use the URL tester to test a path or URL against one crawler or multiple crawler categories.
• View or download the live robots.txt content when available.

Review items may flag robots meta noindex, X-Robots-Tag noindex, robots meta/header conflicts, conflicting robots directives, and robots.txt rules that disallow the current URL.

Social

The Social section inventories Open Graph and X/Twitter metadata. The full workspace includes an editable preview tester for Facebook/Open Graph, LinkedIn/Open Graph, and X/Twitter cards.

• Edit title, description, and image URL fields to preview alternate social snippets.
• Export social metadata as CSV, TSV, JSON, or Markdown.
• Review title and description length signals while editing preview copy.

Review items may flag OG title differences, OG description differences, and OG URL/canonical mismatches.

Style And Visual Review

The Style section extracts computed fonts, color usage, CSS variables, stylesheet URLs, style tag counts, inline style counts, and accessible CSS rule counts.

• Color swatches show the detected value, usage count, and usage category.
• The local color tool converts selected colors to HEX, RGB, and HSL.
• Where supported, the eyedropper can pick colors from the current page.
• Auto-copy can copy a preferred color format when selecting a swatch.
• The accessible color palette setting improves visual severity states for colorblind users.

SERP Preview

The SERP section builds editable desktop and mobile Google-style snippets from the current title, URL path, favicon, and meta description.

• Edit URL/breadcrumb, title, and description text.
• Toggle rich elements such as rating, review count, price, availability, delivery, returns, store nearby, read more, forum/Q&A, related rows, sitelinks, and pill links.
• Download desktop or mobile previews as PNG or WebP.
• Text is truncated by measured pixel width for desktop and mobile preview limits.

Webmaster Tools

The Webmaster Tools section provides direct shortcuts and local helpers for Google Search Console and Bing Webmaster Tools.

• Open Search Console Domain Property or URL Prefix Property views.
• Open Search Console Performance reports filtered to the current page for either property type.
• Open Search Console indexing reports for either property type.
• Open Bing Domain Site or URL Prefix Site views.
• Inspect the current page in Bing Webmaster Tools.
• Add percent-change chips to supported Search Console and Bing comparison rows and scorecards.

Tools

The Tools section collects fast local actions and external lookups for the current page.

• Highlight nofollow, sponsored, and UGC links on the current page.
• Toggle JavaScript for the current site in Chrome and Edge, then reload. Firefox and Safari do not expose this Chromium-only extension API.
• Run Google site search, HTTP-version search, page search, page image search, or site image search.
• Export visible Google search results as CSV and copy the current Google query on supported result pages.
• Search the current Search Console property when using Search Console.
• Open Ahrefs, Archive.org, Moz Link Explorer, Semrush, Similarweb, Schema Validator, or Rich Results Test.
• Review the rendered accessibility tree with landmark, heading, control, image, issue, role, name, and relationship summaries.

Third-party lookup buttons open new tabs only when clicked. Shumway SEO Toolkit does not send background requests to those services.

Exports

Exports are generated locally in the browser from the current page audit. The full workspace lets you choose datasets and formats.

• Datasets: Overview, Headings, Links, Images, Schema, Social, and Style.
• Formats: CSV, TSV, JSON, and Markdown in the full workspace.
• Popup formats: copy JSON, CSV, TSV, JSON, XLSX, and print report.
• Additional outputs: image file downloads, SERP PNG/WebP previews, accessibility tree JSON, and schema JSON.
• Full export bundles the selected audit data into a single selected format where supported.

Context Menu Actions

Right-click page, link, or selected content where supported to access Shumway SEO Toolkit actions.

• Open SEO Workspace.
• Highlight Nofollow Links.
• Toggle JavaScript For This Site in supported browsers.
• Search Indexed Pages For This Domain.
• Image Search This URL or Image Search This Domain.
• Download Image Files, Overview TSV, Headings TSV, Links TSV, or Schema JSON.
• Open the current page or link in Schema Validator, Rich Results Test, Ahrefs, Archive.org, Moz, Semrush, or Similarweb.
• Export visible Google results and copy Google query on supported Google search pages.

• Search the current Search Console property on supported Search Console pages.

Settings And Accessibility

Settings are stored in browser extension storage and stay local to the browser unless the user changes them, resets the extension, or uninstalls it.

• Accessible color palette: uses a colorblind-friendlier severity system. Blue indicates passed or indexable, yellow indicates review, plum indicates critical, and neutral states remain subdued.
• Run heavy checks when idle: advanced performance preference for keeping initial page checks responsive when heavier checks are available.
• Theme toggle: the full workspace stores a light/dark preference separately from page content.

Privacy Model

Shumway SEO Toolkit reads the active tab only when used. Page analysis and exports run locally in the user's browser. The extension does not use analytics, tracking pixels, remote logging, accounts, background crawling, or third-party data collection APIs.
