Content Architecture Gap Checker methodology

This tool discovers same-host pages from robots/sitemaps and internal links, classifies them against a documented B2B growth taxonomy, and recommends missing page types. It is not a keyword-demand, Search Console, or ranking-gap analyzer.

Discovery

01How the crawl works

  • Fetch the start URL and extract same-host internal links
  • Read robots.txt for Sitemap: lines when present
  • Parse sitemap / sitemap index XML (public text fetch, SSRF-hardened)
  • Prioritize taxonomy-looking paths, then BFS more internal URLs
  • Hard cap: about 36 HTML pages and 200 sitemap URLs per run
  • Optional: competitor homepage + sitemap themes (not rank tracking)

Scoring

03How the architecture score is calculated

  • Weighted taxonomy points: dedicated = full, weak = partial, missing = zero
  • Thin crawls are capped (single-page HTML cannot earn an exceptional grade)
  • Evidence coverage reflects pages fetched vs budget and sitemap breadth
  • Recommendations suggest concrete paths/titles for missing or weak areas
