Geo Header Preview (Localization Tester)
Test localization behavior by simulating region and locale request hints through headers + cookies. This is header-based simulation only, not true geo-IP traffic.
Known limitations: Results may differ from real visitors from that country. Many sites ignore hint headers, rely on IP, require JavaScript, or block automated fetches.

Use cases
- Validate region redirects for campaign URLs and UTM landing pages.
- Check language/currency banners before market launches.
- Compare regional landing variants quickly without VPN egress.
FAQ
Why does this not always match real visitors?
This tool simulates locale and country hints using headers and cookies. Real geo-IP routing may still differ because origin servers and CDNs often use IP geolocation.
How can my site respond to this test?
Read Accept-Language, region hint headers, and explicit locale/country/currency cookies on your server, then return localized content or redirects.
Why is the preview incomplete for some sites?
Some pages require heavy client-side JavaScript or block bot-like requests, so server-fetched HTML previews can be partial.
