Use Relative Countdown Timers

Increase signups with FOMO! Add a relative countdown timer that activates when a visitor first sees a pop-up. If time runs out before the user converts, the timer will disappear. But the offer will still be available to other prospects. A pop-up with a tempting offer and a timer has a 112% higher CR than a regular one.

Inspire with Video Widgets

Catch your website visitors' attention with video widgets. Show new cool products or features and offer email sign-ups for discounts. Leads may turn into buyers quickly, as nearly 91% of consumers say videos inspire them to make a purchase.

Benefit from Promocodes

Add a promo code to a widget and target its display to new site visitors, or offer a nice discount in an exit-intent popup. 4 out of 5 consumers are encouraged to make their first purchase from a new company when they see an offer with a discount code. Let visitors complete their purchases, then offer them to subscribe to your newsletter.

We decided to introduce a floating information widget. It is not intrusive, but it had to appear with each new session. Claspo was the easiest way to do this. The platform is easy to understand, you can figure everything out in half an hour.
