# `PhoenixKitWeb.Components.Core.CrawlerMetas` [🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v2.13.7/lib/phoenix_kit_web/components/core/crawler_metas.ex#L1) Head metas owned by the Crawlers module: the global `noindex, nofollow` directive and search-engine verification tags. Self-contained on purpose — it reads the settings itself (ETS-cached), so it works in ANY root layout with zero assigns, exactly like `phoenix_kit_favicon`. That matters because most installs render the head in the HOST app's root layout, where core's assigns don't reach: an assign-based meta in core's own layout files renders only on installs using core's shells. Embed in a host root layout's ``: The noindex directive renders whenever it is set, **not** gated on the module toggle: it is a safety switch, and the long-standing contract (pinned by `auth_crawlers_no_index_test`) is that a set directive is honored — a disabled module must not silently expose a staging site to indexing. (`disable_module/0` clears the directive through the API; this covers state written around it.) The verification metas ARE module-gated — they are new behavior, and module off means off. Never raises — with no database (installer context) it degrades to empty. # `crawler_metas` Robots directive and verification meta tags, from current Crawlers settings. --- *Consult [api-reference.md](api-reference.md) for complete listing*
