Signals are site-wide technical checks — structured data, sitemap, robots.txt, llms.txt, metadata, heading structure, alt text, and more. Each one simply shows PASS or FAIL.
Signals — pass/fail technical checks for your whole site.
This page is not marketing work, and you don't need to interpret every row. Send the list of failed signals to your web or development team — most are one-time fixes, and they overlap with the GEO-category recommendations your team already has from step 2.
Outcome: your web team has the failed signals and owns the technical fixes.
