SEO Scrubbox

What is SEO Scrubbox?

SEO Scrubbox is a Chrome extension for technical SEO analysis, live visual crawling, and page-level diagnostics. It combines on-page checks with HTTP and rendering-aware analysis so users can inspect how a page appears before and after JavaScript rendering, alongside signals such as canonicals, meta robots, redirects, structured data, hreflang, and sitemap discovery.

The product is aimed at SEO professionals, developers, and technical marketers who need to inspect crawl behavior directly in the browser. It also includes a visual crawler called ScrubberCrawl that maps site structure as pages are discovered, helping users review internal linking, indexability, and crawl issues without switching to a separate desktop crawl tool.

Key Features

• Live visual crawler with node-graph views: ScrubberCrawl builds a real-time site graph as URLs are discovered, with layout options for directory routing or crawl depth so users can inspect site structure in different ways.
• Metric-based node styling and filters: The graph can map node size and color to status codes, indexability, unique inlinks/outlinks, word count, and file size, and it can be filtered by indexability or HTTP status for faster issue spotting.
• Crawl history, snapshots, and CSV transfer: Previous crawls are saved for later review, and crawl data can be exported to CSV or imported from CSV to visualize existing data in the graph.
• Render-aware page checks: The extension compares raw view-source and rendered output to detect differences in canonicals, meta robots, Googlebot directives, titles, and meta descriptions after JavaScript executes.
• On-page overlays and signals: It can highlight rel="nofollow" links and data-nosnippet elements directly on the page, show indexability status from the extension icon, and detect noindex, nofollow, none, and X-Robots-Tag signals.
• Deep audit controls: Users can tune crawl speed, concurrency, internal URL limits, and sitemap limits, and staging mode can pass session cookies and authorization headers for protected environments.
• Sitemap, link, and hreflang analysis: The tool discovers sitemaps from robots.txt, distinguishes sitemap index and URL set structures, checks internal links and redirect chains, counts link frequency, isolates JavaScript-injected links, and validates hreflang return links.
• Server and caching diagnostics: It also audits security headers such as CSP, HSTS, and X-Content-Type-Options, plus cache and compression behavior including Cache-Control, ETags, Vary, and Brotli/Gzip support.

How to Use SEO Scrubbox

Install the Chrome extension and open the page or site you want to inspect. Use the on-page checks for quick signals, or launch a crawl with ScrubberCrawl to map pages, filter the graph, and review discovered URLs.

For deeper audits, adjust crawl limits, delays, and concurrency, then inspect redirect chains, canonicals, structured data, hreflang, sitemap discovery, and server headers. If you need to test rendered behavior, toggle JavaScript on or off and compare the rendered result with the raw source.

Use Cases

• Technical SEO audits: Review canonical tags, meta robots directives, redirects, sitemap visibility, and internal link structure during a site audit.
• JavaScript rendering checks: Compare source and rendered HTML to see whether scripts change titles, descriptions, canonicals, or crawl signals.
• Site architecture review: Use the live graph to understand crawl depth, directory structure, and how pages connect through internal links.
• Staging and protected-site checks: Crawl pre-production or password-protected pages by passing active session cookies and authorization headers through staging mode.
• Structured data and international SEO review: Inspect JSON-LD presence and validate hreflang status codes and reciprocal return links.

FAQ

• Does SEO Scrubbox analyze both source and rendered content? Yes. The product description says it shows raw view-source and fully rendered states, and compares signals before and after JavaScript rendering.
• Can it crawl protected environments? Yes. Staging mode is described as supporting active session cookies and authorization headers for staging or password-protected sites.
• Does it export crawl data? Yes. The visual crawler supports CSV export and CSV import for reuse in the graph view.
• Is there a crawl limit? The description says the free crawl cap is 500 URLs per run.
• Does it cover server and header checks? Yes. The product includes checks for security headers, caching behavior, and compression signals.

Alternatives

• Desktop site crawlers: Tools in this category are typically used for large-scale SEO audits and may offer broader crawl reporting outside the browser, but they do not center the workflow inside Chrome.
• Browser-based SEO inspection extensions: These focus on quick page-level checks, similar to SEO Scrubbox, but may offer fewer crawl-graph and HTTP audit features.
• Developer-oriented HTTP debugging tools: These are useful for headers, redirects, and rendering behavior, but usually lack SEO-specific checks such as hreflang, noindex signals, and sitemap analysis.
• Spreadsheet-based crawl analysis: Exporting crawl data to CSV and analyzing it manually can work for reporting, but it does not provide the live graph, overlays, or in-browser diagnostics described here.
