Cookie banners are often geo-targeted
Most consent management platforms let a website decide who sees the cookie banner based on where the visitor connects from. A common setup shows a full GDPR consent banner to visitors from the European Union and the United Kingdom, a "Do Not Sell or Share" notice to visitors from California, and nothing at all to everyone else.
The website is not doing anything wrong by configuring it that way. But it means there is no single answer to "does this site have a cookie banner?". The answer depends on where you look from.
Platforms with geo rules include Consentmo, CookieYes, Cookiebot, OneTrust, Usercentrics, and most Shopify and WordPress consent apps. The decision is made from the visitor's IP address, so a browser language setting or a VPN-less "simulate EU" flag does not change what the site serves.
