I read this article which helped break the problem down a little: http://copyhackers.com/2013/02/writing-a-page-for-2-audiences/<p>I was wondering if anyone else has a good approach.
Can you segment the user groups in your advertising? If it's possible to push the right people to the right landing page, that would be ideal.<p>Otherwise, make sure that both segments actually pay money and use the website for information to make a buying decision. I assume they do. If that's the case, imagine a site for patients interacting with doctors. The landing page <i>could</i> focus on the patients and how they benefit. Then doctors (who are much more familiar with the process) will take second place because they naturally see how they fit in the ecosystem.<p>Is that what you're looking for?
