seo/indexable

Why

A noindex left over from a staging build, or a robots.txt that blocks the site, removes pages from search results entirely. It is the single heaviest SEO audit in Lighthouse, because nothing else matters if the page cannot be indexed.

Fix

Set robots meta per environment from configuration (noindex only on preview and staging), keep it in the server HTML (not toggled by script), and keep noindex only on pages that should not appear (search results, cart, account). A page you want removed must stay crawlable so the noindex is seen; do not also block it in robots.txt.

Examples

<!-- staging only -->
<meta name="robots" content="noindex, nofollow">
