I am using geolocation DNS to block some countries. Visitors coming from these countries will be directed to another web server with a blank web page with few words and contact email address.
I see our Alexa rank dropping a lot, and no keyword can find our website now (if no old customers, we would die now), so I'm wondering Google take our blank web page as a cloaking.
Should I respond 404 status page?
If Googlebot coming from USA, it will see the normal page. But if Googlebot coming from the countries I'm blocking, it will see another web page with only few words and contact email address.
I'm wondering it would cause Googlebot considering this as a cloaking.
