What is a call to action?
A call to action (CTA) is the prompt that asks a visitor to take the next step. It is usually a button or a link, such as "Call us", "Book a visit" or "Get a quote". It turns a reader into an enquiry.
Every page on your website should have a job. The call to action is how the page does that job. A visitor who reads your services page and then finds no clear next step will often leave. A visitor who sees "Get a free quote" right after reading has an easy path to you.
The UK government design system guidance on buttons uses the same idea. It says to use the main button style for the main call to action on a page. It also warns that more than one main call to action reduces their impact and makes it harder for users to know what to do next.
What are some examples of a call to action?
A good call to action starts with a verb and says what happens next. Here are examples from illustrative small businesses, not real firms. Each one fits a different kind of visit.
- A plumber: "Call now for a same-day visit". The visitor has a leak and wants help today.
- A café: "Book a table". The visitor has already decided to come.
- A wedding florist: "Ask about your date". The visitor wants to check before committing.
- An accountant: "Book a free first chat". The visitor wants to meet before paying.
- An online shop: "Add to basket". The visitor has found the product.
- A gym: "Try a free class". The visitor wants a low-risk first step.
Notice what is missing. None of them says "Submit", "Click here" or "Learn more". Those words tell a visitor nothing about what they will get.
How do you write a good call to action?
Say exactly what will happen, in the visitor's words, starting with a verb. The government guidance says to write button text in sentence case, describing the action it performs. "Book your boiler service" beats "Submit" because the visitor knows what they are agreeing to.
- Start with a verb: book, call, get, ask, try or visit.
- Name the result, such as "Get my quote" rather than "Send".
- Keep it short enough to read at a glance on a phone.
- Lower the risk where it is true, for example "Free, no obligation".
- Match the promise on the next page. If the button says "Book a table", the next page must let them book.
The words around a link matter too. The Web Content Accessibility Guidelines (WCAG) page on link purpose in context asks that the purpose of each link is clear from its text or its context. It adds that meaningful link text helps people who move from link to link with a keyboard.
Where should a call to action go on a page?
Put it where the visitor is ready to act. That usually means near the top of the page, again after the main explanation, and at the end. On a long page, repeat the same action rather than adding new ones.
Think about the order a customer reads in. First they want to know they are in the right place. Then they want a reason to trust you. Then they want the next step. A button placed before the reason can feel pushy. A button placed only at the very bottom can be missed.
A landing page is built around one call to action from top to bottom. Our guide on how to make a landing page for a small business shows how the page and the button work together.

How should a call to action look on screen?
It should look like something you can press, stand out from the rest of the page and be easy to tap with a thumb. Clear contrast, enough size and enough space around it do most of the work.
- Contrast: the WCAG page on minimum contrast sets a ratio of at least 4.5:1 for normal text, and 3:1 for large text. The words on your button should meet it against the button colour.
- Size: the WCAG page on minimum target size asks for targets of at least 24 by 24 pixels, or enough space around smaller ones. Bigger is kinder on a phone.
- One main style: give the main action one strong style and keep other buttons quieter, so the eye goes to the right place.
- Real text: keep the words as text, not part of an image, so screen readers and search engines can read them.
These are the minimum standards, not the target. A button that just passes can still be hard to spot on a busy page.
Are pop-ups a good call to action?
Usually not on a small business site. A pop-up that covers the page before someone has read it gets in the way of the very thing they came for. A clear button in the page itself does the same job without the annoyance.
Google's guidance on avoiding intrusive interstitials and dialogs says interrupting users with them may frustrate them and erode their trust in your website. It adds that intrusive dialogs make it hard for search engines to understand your content, which may lead to poor search performance. It suggests banners that do not block the content instead.
Why does a good call to action take real skill and time?
Because the button is the last step of a whole page, not a sticker added at the end. Getting it right means understanding your customers, writing the page that leads to it, designing it for every screen and then checking what people actually do.
- Knowing the customer: what they worry about, which words they use and what they need before they will act.
- Writing: a short, honest promise that matches the page it leads to.
- Design: contrast, size, spacing and one clear main action on every page, on phones as well as laptops.
- Accessibility: buttons that work with a keyboard and a screen reader, and link text that makes sense on its own.
- Follow-through: a form, phone number or booking page that works, and replies that arrive fast.
- Checking and adjusting: watching which pages lead to enquiries and fixing the ones that do not.
A worked example
Priya runs an illustrative florist in Guildford. Her home page ended with a grey "Submit" button under a long form, and wedding couples rarely got in touch.
The page now opens with her wedding work and a bright "Ask about your wedding date" button. The same button sits after her photos and again at the end. The form asks only for a name, a date and a phone number. Couples now know exactly what happens when they press it.
None of those steps is hard on its own. Together they take time, and they are easy to get wrong when you are also running a business. More ideas sit in our guide to getting more leads from your website.

Common questions
What does CTA stand for?
CTA stands for call to action. It is the button or link on a page that asks the visitor to take the next step, such as booking, calling or asking for a quote.
How many calls to action should a page have?
Give each page one main action. You can repeat the same button several times on a long page, but avoid offering several different main actions, because that makes it harder for visitors to know what to do next.
What should a call to action button say?
Start with a verb and say what will happen, such as "Book a table" or "Get my quote". Avoid vague words like "Submit" or "Click here", which do not tell the visitor what they will get.
