Sticky bottom bars work on mobile
On mobile, the bottom of the screen is where the thumb rests naturally. A persistent CTA bar anchored there puts the action in the easiest possible spot to tap. No scrolling. No hunting. Always available.
This pattern works especially well for product pages, pricing pages, and any long-form content where the user needs to scroll extensively before deciding. The CTA follows them. When they're ready, it's there.
The bar should be minimal: one line of text and one button. "Get started - Free trial" or "$49/mo - Buy now." Not a full toolbar. Not multiple actions. One thing, clearly communicated, always available.
Show the bar only after the user has scrolled past the primary CTA on the page. If the original CTA is visible, the bar is redundant. Once they scroll past it, the bar appears and stays. This avoids the awkward moment of two CTAs visible at the same time.
Add a sticky bottom bar to your mobile product or pricing page. One button, one line. Show it only after the user scrolls past the main CTA.
