Splash Pages For App Downlowds

[Cash4Books]

Hi,

We currently have a very simple splash page that Android and iPhone users see when they land on our homepage. The screen gives them the option to download our app or move on to the full website. If they choose to go to the site they are redirected to our homepage.

Is this going to have any negative impacts on our rankings? I'm not sure how the Google bot treats this type of page.

We have also talked about replacing the splash page with a modal window, but I'm concerned that this will increase the load time of the home page on mobile devices.

Does anyone have any experience with a similar situation or any advice? Thanks in advance!
