Have you ever thought, what motivates users to view your website or online storefront? Sure, you will think about a great design of a website, user-friendly UI or astonishing product or service with attractive images. However, these are the common features that all websites or e-commerce site owners are trying to add to their to-do lists.

You can also find tons of managers who struggle with the engagement and getting users interested in what the company offers. If you find yourself in that position, you should definitely improve a call-to-action on your website. So what is call-to-action or so-called CTA?

Call-to-action is a marketing expression that simply means a specific action from your target audience. CTA encourages your recipients to make a certain action immediately.

For example, if you own your e-commerce site and selling products, you can add to a description a call for engagement like the “Buy today” or “Special offer” buttons, and this way create effective CTA. However, to show your clients a killing CTA, you have to:

  • Keep it simple - you should place simple call-to-actions on links or buttons you share in order to triple your leads. Content and call-to-action must not overwhelm your recipients. This way your potential customers will easily understand what they will get after clicking on the ad. For example, the Amazon marketplace in their promotional emails applies a plain “See more” button near their brief description about products.

  • Highlight some discounts - incentives are coupon codes that can be a nice CTA to encourage client’s decision to purchase. With 50% coupon discount, would your clients be more motivated to click on the link? The possibility that recipients of your promotional email will click to complete a purchase is undoubtedly higher.

  • Add action words - it is very important to include strong verbs and nouns such as “buy”, “Sale”, “Add to cart”, etc. You need to include expressions that clients are familiar with, this way you will avoid any confusion and misunderstanding. As well, do not be afraid that your words are too strong, it is even great to give your users a command to action. For example, you can use the following CTAs for your promotional banners in an email signature: Buy Today, Sale!, Get. Purchase. Order, I need this!, Shop, It’s Free, Register.

  • Do not forget to Alt text. This enables anyone who receives your email to hover over an image and have an initial idea about what they might get themselves into. The image Alt text is always required  for the purpose of validating images
  • Do not use images that do not work well with the written text for reasons, such as large size or adding too many images to a single email signature. The images in an email address must be able to complement the written text and not overwhelm it.

And the call-to-actions will make it look more attractive to the email recipients. 

#5. Keep Your Message Clear
