Frequently Asked Questions
Common questions about Mobile First Visit Redirect Checker.
What is a mobile first visit redirect?
It is a redirect that only happens when a mobile visitor opens a site without an existing cookie or session.
Why is it hard to detect?
After the first visit, cookies may hide the redirect, so repeated checks may show a normal page.
Is it a SEO risk?
It can be, especially if Googlebot sees a normal page while first-time mobile users are redirected elsewhere.
Does this require global nodes?
No. Mobile first visit logic can be checked with user-agent and cookie comparison from the current server.
