What are call to actions for Facebook?
A call-to-action button (or CTA button) directs your Page visitors to do something specific, like visit your website or call your store. To add a CTA button, start on your Page. Below your Page's cover photo, click Add a Button. You'll see a Preview section at the top that shows what your button would look like.
What are good examples of calls for action?
“Buy Now” or “Download Now” are typical examples of simple calls to action. But a CTA can run longer, too, such as “Subscribe today so you'll never miss a post.” The possibilities are endless. A good CTA can help with decision fatigue and give meaning to your content.
