UX Question

Hi

I just wanted to know if and/or how I should do this. I want to display a banner to the user advertising that our website has an iPhone app. I then want to give the user the option to close this banner. I also don't want this banner to show up for the remainder of the users time on the website, so I thought I would put the users choice into a session and only display it if the session doesn't exist.

1. Would it be bad practice to have something up there that the user can close? E.g. I know having a banner can be a hindrance hence giving the user the choice to close it, but I think the banner would be relevant to the user...​

2. Would storing their choice in a session be the best way to do it to prevent the banner showing for the remainder of their time on the website or is there a better way to do it?

3. If none of the above, how would you go about advertising the fact that there is an iPhone app for the website? I did set it up on a media query to only display if the user was on an iPhone, but it wasn't converting very well and I'd rather everybody see it than just iPhone users.
​

Thanks for any advise you can give.

 

Purely personal prejudice:

I find those disposable banners at best to be annoying and more likely to be a royal PITA; think youtube messing with your watching the video. Announce/advertise your app in a small box at your content's heading level. Put it in the side column or float it at the top of the content. In that box, simply tell your visitor you have the app and link to a page that explains the usage and features. That page should have a go-get-it link.

The box's location will ensure folks will see it, and once seen a few times, will not distract from why they came to the site.

cheers,
