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

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

  • https://glassumbrella.io/auth/login/google-oauth2/?next=/ — 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://glassumbrella.io/auth/login/?next=/, https://glassumbrella.io/auth/register.

warning Hero/LCP image is lazy-loaded (loading=lazy delays LCP)

Rule images.no_lazy_lcp_candidate · Performance · 1 occurrence(s)

  • https://glassumbrella.io/get-involved/ — the likely hero/LCP image (the-smithy-1_raw.svg) has loading="lazy" — Google explicitly warns against lazy-loading the LCP image, because it delays the fetch until layout completes. Remove loading="lazy" from the first significant image and add fetchpriority="high" instead.
