Warnings (10 rules)

warning Control has no accessible name

Rule agent.control_no_name · Agent Readiness · 7 occurrence(s)

warning Noindex page receives internal links (crawl-budget waste)

Rule budget.noindex_linked · Budget · 1 occurrence(s)

  • https://lanzalocode.com/auth/google/redirect — this noindex page has 2 internal inlink(s) — Googlebot follows them, fetches the page, then drops it unindexed, spending crawl budget for no indexing benefit (and the links leak equity). Remove/redirect the links, or drop the noindex if the page should be indexed. Linked from: https://lanzalocode.com/login, https://lanzalocode.com/register.

warning Thin content (low word count)

Rule content.thin · Content · 4 occurrence(s)

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

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

  • https://lanzalocode.com/ — https://www.lanzalocode.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 Duplicate <title> across pages

Rule duplicate.title · Duplicate · 3 occurrence(s)

warning noindex + nofollow (blocks link equity flow)

Rule index.noindex_nofollow · Indexability · 1 occurrence(s)
