It's hard to imagine a modern website without buttons. They guide users through the shopping journey, encouraging registration, and completing transactions. While this element may seem simple, its design requires an understanding of usability principles and the psychology of perception.
What is a button?
Let's start with the basics: what exactly a button is. A button is an interactive interface element that, when clicked, triggers a specific action.
This could be navigating to another subpage, submitting a form, downloading a file, or adding a product to the cart. Technically, a button is a graphical control element that connects a page's visual layer with its functionality.
A typical button on a website consists of three layers: a background (usually a rectangle with rounded corners), a text label, and so-called states that change the element's appearance in response to user behavior – when the cursor is hovered, when the button is clicked, or when the button is deactivated.

What does button mean in marketing?
From a business perspective, a button most often takes the form of a call to action ( CTA ). This is what can convert a passive visitor into a customer, subscriber, or registered user.
How to write a CTA that actually increases conversion?
Industry research suggests that the text of a button's label impacts conversions more strongly than the color of the button. A well-written CTA communicates a benefit, not an action—that's why "Get a free quote" works better than a vague "Submit." It's also worth considering length: labels of two to five words are recommended as the most readable, as users register them at a glance before deciding whether to click.
Types of buttons
Buttons can be divided according to their function:
- action buttons – initiate a specific action, such as “Buy now”, “Add to cart” or “Save changes”,
- navigation buttons – make it easier to navigate the website, leading to the home page, the previous section or the next step of the process,
- social buttons – allow you to share content or react to it on social media,
- secondary buttons – used for less binding actions (e.g. “Add to favorites”), they should be less visually expressive so as not to compete for attention.
In design, there's a saying about the principle of a single dominant button within a view. When multiple elements share the same visual weight, the user loses orientation and the number of abandoned paths increases.
How to design an effective button?
The effectiveness of a button depends on several factors. Contrast is paramount – the button must clearly stand out from the background. The text on the button should achieve a contrast ratio of 4,5:1, while interface elements should achieve a contrast ratio of at least 3:1, according to WCAG. The size of the touchpad is equally important. Apple recommends a minimum size of 44 x 44 pt, while Google recommends 48 x 48 dp, as smaller elements make it more difficult to use on touchscreens.
Frequently asked questions about buttons
How to design the perfect button?
The label should be short, ideally two to five words, and clearly announce the click's effect. It's also worth ensuring the button's visible states and its placement in line with the natural reading direction, i.e., along the popular F and Z patterns used by users to scan the page.
No project is complete without testing. A/B button testing, which compares variants differing in content, color, or position, allows us to determine what actually works for a given audience. The order is often crucial: first, it's worth checking the label's content, then its placement, and finally the visual aspect. In many tests, changes to the message and value proposition have the greatest impact on the results.
Small element, measurable results
Although a button is a minor element in the overall website context, it determines whether a visitor will complete the intended action. A well-designed button combines readability, accessibility, and a clear message, and its effectiveness is confirmed by regular testing. Treating buttons as a sales tool, rather than merely interface decoration, directly translates to a website's performance.
A button is a key, interactive element of the user interface (UI). It's used to trigger a specific action when clicked, such as submitting a form, adding a product to the cart, or navigating to another page.
- Primary Button: This button has the most striking color and size. It controls the most important action on the page (e.g., "Buy Now").
- Secondary Button: This button is more subdued (e.g., has only a border). It is used for alternative actions (e.g., "Cancel" or "More Information").
This is a call-to-action button whose main task is to encourage the user to perform a specific, business-desirable conversion (e.g., "Subscribe to the newsletter," "Download the e-book").
- Filled button – a classic button with full color filling.
- Outline / Ghost button – a transparent button with only a frame and text.
- Icon button – a button in which the text has been replaced by a clear icon (e.g. a magnifying glass icon for searching).
- Text button – a button that looks like plain text, but responds to clicking.
Color builds visual hierarchy and influences user psychology. Action buttons should contrast with the page background to immediately catch the eye. Colors often convey emotional meaning (e.g., green for success/purchase, red for error/delete).
These are visual changes to a button that inform the user of its status. These include Normal, Hover, Active, and Disabled.
The text on the button (the label) should be short, clear, and formulated as an action-oriented verb (e.g., "Register," "Check the offer") so that the user knows exactly what will happen after clicking.
Summary
The above article covers the following topics:
- A button is an interactive, graphical interface element that, when clicked by a user, triggers a specific action on the page.
- In marketing, a button functions as a call to action (CTA), which increases conversions most effectively when its short label communicates a direct benefit to the customer.
- Buttons are divided into action, navigation, social and secondary buttons based on their function, but only one primary button should dominate a single screen.
- An effective button should stand out with appropriate contrast, size and positioning, have a short, clear label, and its final shape should be verified using A/B testing.
- A well-designed and regularly tested button is not just a decoration, but a key sales tool that determines user actions and the results of the entire website.
