What is a sticky CTA?
"Sticky bars" are CTAs that slide in at the top of the visitor's browser window. Stick bars are useful when you need to show a promotion to visitors browsing your website, without getting in the way of your website's content.
What are sticky Buttons on website?
Sticky Bars are the less intrusive cousin of the noble Popup. They appear at the top or bottom of the page (and sometimes the sides) when a visitor arrives, leaves, scrolls down or up, stays on the page for a certain time period or clicks a link or button.
