Modals—also known as modal boxes, modal dialogs, or most commonly modal windows—contain important information and usually appear on top of the main page content. This information may include a promotion, a free downloadable resource, a bonus, a discount coupon, or a newsletter subscription form.

When a modal window appears on the user’s screen, the content of the main page becomes blurred or inaccessible until the visitor finishes interacting with the modal. This can happen either by completing the suggested action or simply closing the window.

It is true that this solution interrupts the user’s browsing session, which might make some people think modals are annoying. Fortunately, this is not necessarily the case. With proper design, modals can positively influence user experience and significantly support lead generation. To achieve this, however, you need a skilled web designer, a solid understanding of your market, and some creativity to identify the situations where modals can be used effectively.
