The Sign Up Page
As pointed out by Guy Kawasaki,
“A site’s signup page is the second most important page on a site (the most important is the home page itself) because this is where you’re asking for committment.”
A sign-up page should be suitable as a landing page for AdWords campaigns, mail-out campaigns and potentially any other marketing campaigns.
My sign up page will feed into the CRM, and also initiate the Set up process.
Turtle Interactive has an excellent article today, The art of the sign up page.
Update: Some useful data on sign up pages from Smashing Magazine.
