What is a call to action (CTA) and how do you write one?
A call to action (CTA) is a prompt that tells someone what to do next. In digital marketing, it is the button, link or sentence that turns a visitor into a lead or a customer. Without a clear CTA, even the best content leaves people wondering what happens after they finish reading.
A CTA can be as direct as "Book your free consultation" or as gentle as "Read the full guide". The wording, placement and design all affect how many people act on it. Getting it right is one of the fastest ways to improve conversion rates without changing anything else on the page.
The types of CTA
Not every CTA asks for the same thing. The type you choose depends on where the person is in their buying decision.
Lead generation CTAs aim to capture contact details. Examples include "Download the checklist", "Get your free SEO report" or "Join the newsletter". These work well at the top of the funnel, when the visitor is still researching.
Sales CTAs ask for a direct commitment. "Book a call", "Start your free trial" and "Buy now" all sit at the bottom of the funnel. These need more trust and context behind them. A visitor who lands on a page and sees a hard sell CTA without understanding what they are buying is unlikely to click.
Content CTAs encourage the next piece of engagement. "Read our case studies", "Watch the demo" or "Compare the options" keep someone moving through your site. Internal links that point to relevant next steps are a form of CTA too.
Supporting CTAs sit within the body copy. These are the underlined links that say "Learn more about SEO packages" or "See how we helped a care home grow its organic traffic by 251%". They catch people mid-read who want more detail before committing to the main CTA.
How to write a CTA that works
The best CTAs share the same traits. They use active verbs that tell the reader exactly what will happen. "Get your free SEO report" is clearer than "Access our resources".
They are specific. A CTA that says "Start from GBP 980 per month" gives the reader a concrete reason to click. A generic "Learn more" does not.
They create a low-friction next step. The best CTA is the one that asks for the smallest commitment that still moves the relationship forward. "Run your free SEO report" requires only a URL. "Book a discovery call" asks for 30 minutes of someone's time. Both are valid, but they serve different stages of the funnel.
Where CTAs work best
Above the fold. A hero section with a clear primary CTA tells first-time visitors what you want them to do. On Victory Digital's own site, the hero CTA leads to the free SEO report at https://victory.digital/run-a-seo-report, which is the lowest-friction way for a new visitor to experience what we do.
At the end of content. Someone who has read a full guide is more likely to take the next step. A CTA like "Ready to improve your rankings? Book your free consultation" makes sense after an informative article.
On pricing and comparison pages. When someone is comparing options, a CTA that says "Compare digital marketing packages starting from GBP 849 per month" gives them a decision point. The TrustATrader case study showed how a well-timed CTA on a results page converted readers into enquiries. Organic traffic increased by 400%.
Mid-content supporting links. A sentence that links to a related case study or service page keeps the reader engaged. These supporting CTAs work because the reader is already interested and just needs a path to more detail.
Common CTA mistakes
Too many choices. A page with three competing buttons dilutes the action. Pick one primary CTA per page and make it visually dominant.
Vague language. "Submit" and "Click here" tell the user the action, not the benefit. "Get my free SEO audit" tells them what they receive.
No urgency or reason. A CTA without context feels random. If the surrounding content explains why the offer matters, the CTA completes the argument.
A call to action is the bridge between reading and acting. Write one that respects the reader's intent, matches the page's purpose and makes the next step obvious. That is all it takes to turn a good page into one that converts.
