Findings

Warnings (3 rules)

warning Homepage duplicated across protocol/host variants (no redirect)

Rule duplicate.protocol_host · Duplicate · 1 occurrence(s)

  • https://icalc24.com/ — https://www.icalc24.com/ serves the same homepage content with a 200 and no redirect — Google sees a duplicate. Pick one canonical host/scheme and 301-redirect the others.

warning robots.txt blocks CSS/JS the pages need to render

Rule robots.blocks_css_js · Robots · 1 occurrence(s)

  • https://icalc24.com/ — robots.txt Disallow blocks render-critical CSS/JS under: /static/css/, /static/js/ — Google's renderer can't fetch these, so the affected pages may render blank or thin. Allow the asset path(s) for Googlebot.

Notices (9 rules)

notice Heading levels skip a level

Rule agent.heading_skip · Agent Readiness · 50 occurrence(s)

notice No llms.txt for AI agents

Rule agent.llms_txt_missing · Agent Readiness · 1 occurrence(s)

  • https://icalc24.com/ — no llms.txt found at the site root — add one so AI agents get a curated site summary

notice Page served uncached (no-store/private or CDN bypass)

Rule cache.not_cacheable · Cache · 50 occurrence(s)

notice Large DOM (over 1500 elements) slows rendering & interaction

Rule perf.dom_size_large · Performance · 1 occurrence(s)

  • https://icalc24.com/calculators — the page has 1677 DOM elements (recommended maximum is around 1500) — a large DOM increases style-recalculation, layout and paint cost, hurting LCP and INP. Flatten deep nesting, paginate long lists/tables, and lazy-render off-screen elements.

notice No ETag header (no conditional GET for unchanged pages)

Rule perf.no_etag · Performance · 50 occurrence(s)

  • https://icalc24.com/ — the response carries no ETag header — without an ETag (or Last-Modified) there is no cache-revalidation mechanism, so crawlers re-download the full body every visit. Emit an ETag (a content hash) to enable conditional If-None-Match requests.
