Leave out the guesswork. Set expectations. Being vague won’t get people to click on your button or call to action. People like to be in control. Don’t leave them guessing what the next step will be. Show your users where they stand in lengthy processes. Incorporate progress bars. Be clear about what will happen once they complete a lead form or place an order. Clicking submit without knowing exactly what to expect next creates uncertainty. Uncertainty creates friction—and friction can kill the success rate of your page.
