What is a Call to Action?

A call to action (CTA) is a powerful prompt on a website that directs users to take specific actions. Usually presented as an action phrase, such as ‘Sign Up’ or ‘Buy Now,’ CTAs are typically in the form of buttons or hyperlinks. In the realm of digital marketing, CTAs can appear as text on buttons (CTA buttons) or links in email campaigns that lead users to further actions on webpages.

Why is a Call to Action Important?

CTAs play a crucial role on webpages, acting as signposts that guide users on what to do next. Without a clear and compelling CTA, users may feel unsure about the next steps to take, leading them to leave the site without completing their desired tasks. A well-crafted call to action, on the other hand, removes friction and confusion, guiding potential customers towards the desired actions, and facilitating their journey down the sales funnel. It’s not uncommon to have multiple CTAs on a single page if there are multiple desired actions for users to take.

For instance, if a user lands on a blog article and finds no clear CTA at the end, they are more likely to leave the site without engaging further. Conversely, a CTA at the end of the post encouraging them to read more articles or sign up for an email newsletter can encourage continued interaction with the site.

Examples of Calls to Action

Calls to action can take various forms depending on the context and the goals of the website. Here are some typical examples:

On a Blog:

  • Read more articles
  • Sign up for our newsletter
  • Support our sponsor
  • Share on social media

For a B2B Company:

  • Get started
  • Sign up
  • Free Trial
  • Contact Sales

On an E-commerce Site:

  • Add to cart
  • Checkout
  • Buy now
  • Add to wishlist

An effective CTA clearly communicates what users can expect when they click on a button or take the next action, which can significantly improve click-through rates and overall engagement.

How to Create Compelling Calls to Action

To make CTAs compelling and successful, marketers employ various strategies:

  1. Good Design: CTAs should stand out, so using bright button colors that contrast with the page or email color is an effective approach.
  2. High Visibility: The font size of the CTA should be large enough to command attention and make it the most noticeable element on the page.
  3. Clear Benefit: Clearly state the benefit users will get from completing the action to entice them to click.
  4. Actionable Text: Use action-oriented words like “discover,” “learn more,” and “buy now” to encourage users to take action.
  5. Short in Length: Keep CTAs short and to the point, usually no longer than five to seven words.
  6. Sense of Urgency: Create a sense of urgency to encourage immediate action, such as limited-time offers or deals.

How to Use A/B Testing to Test CTAs

Every audience responds differently to different calls to action, so there is no one-size-fits-all approach. A/B testing, also known as split testing, is an effective method to determine which CTA performs better among your target audience. By creating two versions of a CTA and comparing their performance, you can make data-driven decisions to optimize your CTAs for higher conversions.
