Use when auditing locally-focused or regionally-targeted pages for geo targeting signals, particularly on sites targeting audiences through Bing or regional search engines. Note that these meta tags have no documented effect on Google's ranking.

While Google does not officially support geo meta tags, Bing and other search engines may use them for geographic targeting. For sites with clear regional focus, they provide a low-effort supplementary signal alongside the primary approaches (hreflang, LocalBusiness schema, NAP consistency).
geo.region, geo.placename, geo.position) are not used by Google, but may be read by Bing and minor enginesIn the page <head>, check for <meta name="geo.region">, <meta name="geo.placename">, and <meta name="geo.position"> tags. Verify: (1) geo.region uses a valid ISO 3166-1/3166-2 code (e.g., US-CA for California, GB-ENG for England). (2) geo.position uses latitude;longitude format (e.g., 37.7749;-122.4194). (3) ICBM meta tag matches geo.position if present.
<head>:
<meta name="geo.region" content="US-CA">
<meta name="geo.placename" content="San Francisco">
<meta name="geo.position" content="37.7749;-122.4194">
<meta name="ICBM" content="37.7749, -122.4194">
geo.region: country code + region code.geo.position and ICBM use consistent coordinates.Geo meta tags signal a page's geographic focus to search engines. While Google does not use them as a ranking factor, Bing's guidelines reference them for geo-targeting. They are most useful for regional or local sites wanting to signal geographic relevance without significant development effort. They should supplement, not replace, hreflang and LocalBusiness structured data.
Check <meta name='geo.region'> for a valid ISO 3166-2 value (e.g., 'US-CA', 'GB-LND'). Verify geo.position format as lat;lon (semicolon separator). Flag if geo tags are present but contradict the site's actual target region. Note if geo tags are used without accompanying hreflang or LocalBusiness schema, which are more impactful.

概要と使いどころ
Use when reviewing templates, rendered HTML, or shared components related to Create a custom 404 error page. Validate the final browser-facing markup, not just the source framework abstraction.

Use when reviewing component libraries, page flows, or CI pipelines that need repeatable accessibility checks. Automated testing is strongest at catching structural and attribute-level issues; it does not replace keyboard, screen reader, and manual UX testing.
