Rich Results Eligibility

PASS
1 JSON-LD block(s) declaring 6 schema type(s)
Info::
6 rich-result schema type(s) declared
Inventory of structured-data types on the page (each may unlock a different SERP feature): BreadcrumbList, ItemList, Organization, WebApplication, WebPage, WebSite Search engines decide whether to render rich results based on content quality + page-level signals; declaring the schema is necessary but not sufficient.

Image Optimization
1 issues found across 2 images
PASS
1 issues found across 2 images
Info::
2 image(s) wider than 400px without srcset (no responsive serving)
These images deliver the same asset to every viewport (mobile, tablet, retina). Adding srcset / <picture> lets the browser pick a viewport-appropriate variant and typically saves 40-70% of bytes on mobile. Sample: https://admintoolkit.io/brand/admintoolkit/header_light.svg?v=v21-final, https://admintoolkit.io/brand/admintoolkit/header_dark.svg?v=v21-final.
