Overlay CTA (call to action) refers to a visual element, often in the form of a pop-up or banner, placed on top of a web page's content to prompt users to take a specific action, such as subscribing, making a purchase, or navigating to another page.
Overlay CTAs are designed to capture the user's attention and encourage immediate engagement with a particular offer or message.
An e-commerce website might use an overlay CTA to promote a limited-time discount, prompting visitors to click and access the discounted products.
