From Squeeze Page To Main WordPress Site

Hi All,

I'm trying to implement a squeeze page before a main WordPress site such that :

- the squeeze page is on the main domain name
- when the visitor filled in the squeeze page, it then direct to (maybe a OTO; then to) a full WordPress site

What is the best way to implement above?

Is it installing WordPress on the root and use some sort of squeeze page plugin or a squeeze page PHP/HTML on the root URL and redirect signups to WordPress on sub-directory or ...

Best Regards, William
