A call to action, often called a CTA, is the most important next step you want a particular viewer to take after watching your video. It is more than a donate button or a line on an end card. It is the decision that should connect the video’s story, closing message, on-screen text, destination page, and measurement plan.
For many campaigns, choosing one primary CTA creates useful hierarchy. It does not mean a website can have only one link or that every audience should receive the same request. It means the campaign has one clear priority that viewers can understand and your team can support and measure.
Define success before writing the script
Start with a planning sentence: “After watching, we want [this audience] to [one action] so that [near-term campaign result].” For example: “After watching, we want current email subscribers to give by July 15 so that we can support the summer-meals campaign.”
The action could be donating, registering for an event, subscribing for updates, volunteering, requesting help, or taking a defined awareness-related action. “Raise awareness” may be a worthwhile campaign purpose, but by itself it does not tell a viewer what to do or give the team a concrete result to measure.
Choose the most important measurable action before crafting the CTA and decide how success will be assessed. That approach is consistent with nonprofit CTA guidance from Bloomerang. A completed gift, registration, subscription, petition completion, volunteer application, or qualified inquiry is generally more informative for this purpose than views alone.
Match the ask to the viewer and campaign
A person who already knows your organization and receives regular appeals may be ready for a donation request. A new viewer who has just encountered an unfamiliar issue may need a simpler first step, such as signing up for updates or attending an introductory event. Treating every video as a direct-donation appeal can make the request feel disconnected from where the viewer is in the relationship.
Separate videos or follow-up messages can serve different stages. An awareness video might invite new viewers to subscribe, while a later message to subscribers makes a focused giving request. The important point is that each version has a priority suited to its intended audience.
This clarity also matters in a changing online environment. The 2026 M+R Benchmarks study reports that its participating nonprofits saw higher online revenue in 2025 while organic website traffic declined. That participant-cohort finding is not a rule for every U.S. nonprofit, but it is a useful reason not to assume interested viewers will later rediscover a campaign through search.
Write a specific, action-led CTA
Use a short instruction that begins with a verb and explains the next step. “Give by June 30,” “Register for the workshop,” and “Get the guide” are clearer than “Click here,” “Support us,” or “Learn more” when the destination has a more specific purpose.
The U.S. Web Design System’s button guidance recommends concise, verb-led labels that tell people what will happen when they select them. Apply that same principle to narration, on-screen text, captions, social-post copy, and the landing-page headline. Viewers should not have to interpret different instructions at each stage.
Connect the request to the outcome promised by the story. A fundraising video can explain that gifts support a named campaign, service, or program need. Keep that explanation accurate and understandable. Avoid claiming that a fixed dollar amount will always produce a particular result unless the organization can support that claim. The FTC has emphasized substantiation for claims about who a charity helps and how funds will be used, particularly in its guidance for professional fundraisers.
Build the full path before production
A CTA is a complete viewer path, not just a final frame. Before filming, confirm the destination URL, the donation or registration form, campaign dates, mobile experience, confirmation message, and the person responsible for responding if the action is a contact request.
Then shape the story around that path. The video should establish the problem, show your organization’s relevant work, and explain the viewer’s role before the closing ask. If the landing page says “Give by July 15 to support summer meals,” the video’s spoken close and end card should communicate the same request.
Consider a food pantry planning a summer-meals campaign. Its primary CTA might be: “Give by July 15 to support summer meals.” That decision can guide interview questions toward the summer need, give the closing narration a defined purpose, set the end-card wording, and establish a donation-page headline. The matching success measure is completed gifts through that campaign path. This is an illustrative workflow, not a guaranteed fundraising formula.
Make the priority visible and accessible
One primary CTA does not require removing every other option from a campaign page. A page may still need navigation, privacy, legal, accessibility, or donor-support links. If a secondary action is genuinely needed, make the primary action more visually prominent and keep alternatives related and understandable. Federal design guidance recommends distinguishing the most important action and avoiding too many buttons; its button-group guidance also addresses grouping related actions.
Plan for people who do not watch with sound. Present the essential CTA in spoken narration and readable on-screen text, and include it in the accompanying post or page. Caption the video and provide a transcript. The W3C’s media-planning guidance recommends building accessibility into production, including captions, descriptive transcripts, and description when meaningful visual information is not available through audio. This guidance is a planning resource and accessibility standard; it is not, by itself, a complete statement of any organization’s legal duties.
Measure the action, then improve carefully
Track the link or campaign page associated with the video and establish a baseline where possible. Measure the result that matches the CTA: completed donations for a giving ask, completed registrations for an event ask, or subscriptions for an updates ask.
If you test alternatives, change one meaningful element at a time. You might test the CTA wording, end-card placement, or destination-page headline, but not all three at once. Changing one variable makes results easier to interpret, an approach also recommended in Bloomerang’s CTA guidance.
For donation campaigns, review the request and destination before launch. Charitable-solicitation rules can vary by state, and may include registration, reporting, exemptions, or rules involving paid solicitors, as the IRS explains. Do not assume every organization must register everywhere. Likewise, the federal nondeductibility solicitation notice applies to certain tax-exempt organizations that cannot receive tax-deductible contributions, not to every nonprofit, according to the IRS.
If the CTA leads to an online charitable giving portal operated by an intermediary, confirm that viewers receive clear information relevant to that portal about where funds go, fees, timing, and donor-information sharing. The FTC’s portal guidance is specifically directed to online charitable giving portals, rather than every direct nonprofit donation page.
