Using “no-form” messages for a site-wide flash sale is probably the simplest and most widely used method. These types of campaigns drive urgency, point your visitors directly at the shopping experience, and are relevant to every visitor on your site.
This is a great example because it accomplishes every goal of this type of campaign. If you're running a flash sale on your site, you'll want to think about:
Simple targeting. The message launches almost instantly when you land on the site, making it virtually impossible to miss.
The offer is clear. The 50% off is clear and the focal point of the message. Restrictions do exist and they are easy to see, but the offer is the star of the show.
Clear, compelling design. The contrast of colors and simplicity of design make it easy for a reader to digest quickly and take action on the offer.
Strong call to action. The “shop now” button at the bottom gives you a shortcut to the buying experience to take advantage of the offer. And the link goes to a collection of only the items included in the sale.
The start and end date of the offer is clear. 8 AM to 10 PM, no questions asked.
