(Navigation Element) Behind the widely used abbreviation CTA, designers and content creators mean call to action. This is actually the word of phrase which stimulates users to interact with a product in a way and for the aim it is designed for. CTA elements are the interactive controls which enable users to do the action they are called to. Typical types of such interactive elements in the layout are buttons, tabs, or links.

In the interfaces of all kinds, CTA elements are the core factor of effective interaction with the product, which plays the crucial role in usability and navigability. When all the path of interaction and transitions is built clearly for users but CTA element is not thought-out, placed or designed well, users can get confused and will need to take additional effort trying to achieve their goals. That sets the high risk for poor conversion rate and general user experience. That’s why this navigation element should draw particularly deep designers attention. In any interface, it should be one of the most prominent and quickly noticeable parts to inform users how the product can be helpful or useful for them.

Some call-to-action elements may be represented with icons that don’t require copy using widely and instantly recognized images such as a telephone receiver for making a phone call or the envelope for opening received mail. The app interface presented above shows this case: the button with a receiver is the most prominent interactive element on the screen navigating user to achieving their goals with app quickly, and it doesn’t need the copy to let users understand what action can be done with it.

However, when the image of an icon is not so obvious or can be misleading, it is more effective to use double scheme, when the icon, button, or link is supported with the copy.
