Background
We are in the process of launching a website where ticket inventory and processing are handled by a third party. Our primary means of traffic generation (at least at first) will be through SEO traffic.
One of the things that they require of us is a script that will detect people with an iPhone and, upon entering the site, display a page giving people the option to call for help or continue to the site. (see attached screenshot)
We will still get credit for the transaction (tracked through the phone #) and they say that this increases conversion rate, so it is something that we would like to use, unless it will affect our ability to rank in mobile.
Problem
My concern is that we will be penalized by Google (or rank poorly in Mobile search) because the page that iPhone users (not iPad users) are served is hosted on a different domain and not optimized at all for the keywords people are searching for. This is obviously a non-issue if Google never sees the page, but I have heard that Google will emulate different devices when crawling pages.
Question
Can anyone provide any insight about this? I feel like we are adding value to customers by giving them the option to speak to customer support, but I'm afraid that Google will think we are cloaking or at best providing the same page to anyone entering with an iPhone. Here is a link to the soon-to-be-launched website:http://dev.concerttickets.com.vhost.zerolag.com/ -- so you can check it out on your iPhone.
Is there a possibility that this could effect SEO traffic from other devices?
Any suggests will or advice will be greatly appreciated. Thanks in advance!
