This is something achieved well by guys such as Woobox http://www.woobox.com.
So they allow for the advanced creation and editing of custom html/xfbml landing pages essentially.
Furthermore there is lots of cool stuff you can do to manipulate the users who visit these pages, i.e. “Show a non-like fan this page, show a like fan this page” and loads more.
So my question is, would Unbounce consider applying their logic to Facebook tabs? as a standalone app?
Not sure if theres a way you could use an embed code generated from the unbounce platform to stick that in your custom tab - to work it via iframe or similar?
Would be great to split test, and get actionable reports on those custom tab landing pages.
Kinda follows on from questions someone mentioned elsewhere about using pages created in Unbounce outside of Unbounce… it would all help to make it the holy grail of the “platform” at the end of the day… true platforms solve problems and build others’ businesses
