WordPress is a super easy way to get your sales page created and published so it can be released automatically on your launch date.
With a WordPress-based website, you can create a sales page as far in advance as you’d like, and then set the page to publish on whatever date you wish. I’ve just created a sales page for a client on their self-hosted WordPress website. They are promoting a new event and have a notification sign-up form that gives subscribers a link to view a video preview about the training. We’ve set the video preview page to publish on the release date, rather than have it up and running right away where those not on the subscriber list may find it.
Clients love it that we can get all the information up on the site, and still keep it private until the launch date. Win-win!
