A website can be well designed, well written and fast, and still produce almost no enquiries because it never clearly asks for one. The call to action, usually shortened to CTA, is that ask. It is the button, link or phone number that turns a reader into a customer.
Below are call to action examples for different kinds of business, followed by the rules that make them work. None of this needs a big budget. Most sites can improve their CTAs in an afternoon.
What makes a call to action work
- It names the action and the outcome. “Get a fixed quote”, not “Submit”.
- It matches where the reader is. Someone reading about prices is ready for “Get a quote”; someone reading your blog may only be ready for “See our work”.
- It lowers the risk. A short line beneath, such as “Free, no obligation” or “We reply the same working day”, answers the hesitation.
- It stands out. One colour used only for primary actions, with enough contrast to be obvious.
- There is one main action per screen. Two at most. Five equal buttons means none gets pressed.
- It works on a phone. A button big enough for a thumb, and phone numbers that tap to call.
Call to action examples by business type
The phone number above is a placeholder; always show your real one, formatted the way people write it in the UK and linked so it dials when tapped. The stronger versions are not clever. They are specific, and specific feels safe.

Where to put your calls to action
Place calls to action where decisions happen, not just at the top and bottom. On a typical service page that means:
- In the opening screen, so ready-to-buy visitors do not have to scroll.
- After the price or pricing explanation, the moment a reader decides it is affordable.
- After the proof section, when a review has just answered their doubt.
- At the end of the page, with a summary of what happens next.
- In a sticky bar on mobile for businesses that live on calls, so the phone button is always one tap away.
Primary and secondary actions
Most businesses have one action they want most and one fallback. A salon wants bookings, but some visitors want to see prices first. An accountant wants a call, but some people prefer email. Design for both by making the primary action a solid, high-contrast button and the secondary a quieter text link or outlined button next to it.
Choose the primary action by thinking about what the customer prefers, not what you prefer. Many people, especially younger customers and those browsing at night, would rather fill in a form or book online than ring. Others, especially in emergencies, want to talk to a person now. If you are not sure, offer both and watch which gets used.
Think about the time of day too. A lot of browsing happens in the evening, when you are not answering the phone. If your primary action is “Call now” and nobody picks up after 6pm, the evening visitor needs a second route, such as a quote form or online booking, and a line that says when you will reply. The best calls to action match what the customer can actually do at the moment they read it.
Wording rules for buttons
- Start with a verb: book, call, get, see, request, download.
- Keep the button itself short, two to five words, and put detail in the line underneath.
- Use first or second person consistently: “Get my quote” and “Get your quote” both work; pick one.
- Avoid “Submit”, “Send” and “Click here”. They describe the mechanics, not the benefit.
- Do not promise what you cannot deliver. “Instant quote” must actually be instant.
- Match the button to the page it leads to. If “Book now” opens a contact form, that is a broken promise.
Design details that make buttons easier to press
Make primary buttons large enough to tap easily on a phone, with space around them so people do not hit the wrong thing. Use a colour that appears nowhere else on the page except for actions, and check the text on the button has strong contrast against it; that helps everyone, including people with low vision.
Buttons should look like buttons: a filled shape with clear text. Ghost buttons with thin outlines and pale text are fashionable but easy to miss. Keep the button text as real text rather than part of an image, so screen readers and search engines can read it.
How to tell whether your calls to action are working
Most website analytics tools can count clicks on phone links, form submissions and booking starts as events. Set those up and compare how often each action is used against how many people visit the page. You do not need big numbers to spot a problem: if a page gets steady visits but nobody ever taps the button, the offer, the wording or the placement is wrong.
Change one thing at a time, such as the button wording or its position, and give it a few weeks before judging. Small sites rarely have enough traffic for formal split testing, so watch for clear changes rather than small ones.
Call to action checklist
At Nerdsharks, the call to action is decided before the design starts, because it shapes everything around it. If your current site gets visits but few enquiries, this is usually the cheapest place to start fixing it.
- Every page has one clear primary action.
- Button text names the action and outcome.
- A short line under the button reduces the risk.
- Phone numbers are tap-to-call on mobile.
- The action appears in the first screen and again after proof and pricing.
- The button colour is reserved for actions and has strong contrast.
- The next page delivers exactly what the button promised.
- Clicks, calls and form submissions are tracked.
