[Plugin: SimpleSplash] SEO

Hi

Excited by your plugin but I wanted to be sure I wouldn’t be losing my SE ranking. What I want to achieve is a splash page that appears before the current WP homepage that allows visitors to choose there territory. Would your plugin effect my rankings and if I use it are 301 redirects necessary?

Thanks in advance for your help!
