How to Build a Microsite for Your Nonprofit: Six Use Cases From Real Campaigns

Key takeaways

• A nonprofit microsite is a self-contained website with its own URL, built for one campaign, audience or moment. It does one job that would get diluted on the main site.
• It is not a landing page, which is too thin to carry a story, and not a section of the main site, which is too embedded to feel like its own thing. A landing page is one page with one CTA; a microsite has a story arc.
• Three signals say it is the right format: a start and end date, one specific CTA, and a story that would lose its weight inside your main site's navigation.
• Six formats microsites do better than anything else: anniversary commemorations, artist-led documentary, annual interactive reports, global activation campaigns, reusable program frameworks, and coalition advocacy.
• UNEP's World Environment Day 2022 is the clearest proof of scale. One microsite reached 570,000 visitors and earned coverage in 166 countries.
• Microsites fail three ways: no sunset plan, no integration with the main CRM, no single owner. TUMO Armenia is the counter-example, a $60 million campaign that compounds year over year.
• The cost has collapsed. What used to be a six-figure build is now something a mid-sized nonprofit can ship.

When a nonprofit is staring down an anniversary, an annual report or a campaign with a deadline, the first instinct is to find space on the main site. Add a section. Drop a banner. Put it on the homepage.

That instinct is usually wrong.

Some moments don't belong on the main site. They need their own house: their own URL, their own voice, their own single thing to do. That is a microsite.

This isn't theory. Over fifteen years, Fifty and Fifty has built microsites for the International Committee of the Red Cross, the United Nations Environment Programme, the United Nations Development Programme, the Pulitzer Center, the San Diego Foundation, TUMO Armenia, and a coalition of eye-research organizations fighting to protect federal funding for vision research. Seven different jobs, one format choice. What follows is what we've learned about when that choice is right, and when it isn't.

What a microsite is (and is not)

A nonprofit microsite is a self-contained website with its own URL, focused on a single campaign, audience or moment. Its own navigation, its own voice, its own measurement. The main site keeps doing the main site's job. The microsite does one job well, for a defined window.

That makes it different from two things people confuse it with.

A landing page is one page with one CTA. A microsite has multiple pages, a story arc, and usually more than one path through the content. The ICRC's Decade of Loss microsite profiled five young Syrians in depth, drawn from a 1,400-person survey. No landing page carries that.

A section of the main site shares space with your About page, your blog and your donate button. Your campaign gets pulled in three directions before the visitor reads the headline.

Three signals tell you a microsite is right. The work is time-bound, with a start and an end, even if "end" means it rolls into next year's edition. There is a specific CTA: fund this thing, sign up for this event, contact your representative about this. And the story would lose its weight sharing space with everything else you do.

All three signals, and you have a microsite. None of them, and you have main-site content trying to escape its home. The better fix then is to improve the main site.

Pro tip: microsite or landing page, the one-question test. Could the moment succeed as a single page with one button? If yes, build a landing page. The moment it needs a second page, a story arc, or more than one path through the content, it's a microsite. The line isn't size, it's intent. A landing page captures a conversion. A microsite delivers an experience that ends in one.

What makes a good nonprofit microsite?

The difference between a microsite that compounds and one that becomes a 404 comes down to six traits.

• A single, measurable goal. One CTA the entire site drives toward, not a menu of competing asks.
• A defined lifecycle. A start date, and a decision at the end: retire, redirect or evolve.
• Room to tell the story. Depth, pacing and a visual language a main-site section can't give one moment.
• Integration from day one. Donation, CRM and marketing-automation flows wired in at the start, not bolted on 6 months later.
• A single owner. Someone accountable for maintenance, refresh cadence and the sunset call.
• Focused UX. Minimal navigation, short forms, one clear path through the content.

How to build a nonprofit microsite

1. Define the moment and the one goal. The anniversary, report, activation or campaign, and the single action you want.
2. Confirm it's actually a microsite. Apply the time-bound / specific-CTA / story-weight test. If it fails, it's a landing page or main-site content.
3. Choose the CMS. Webflow for custom, interactive builds. WordPress or Squarespace for simpler ones.
4. Wire integrations first. Donation engine, CRM and marketing automation, so the data routes back to your main systems from day one.
5. Build the story, not only the page. Design the pacing and the path for a human reader.
6. Plan the lifecycle before launch. Assign the owner. Decide now whether it retires, redirects or evolves.
7. Measure against the one goal. Track the single conversion, not vanity traffic.

Use Case 1 — Anniversary and commemoration microsites

Some stories are too big to share space with anything else. The anniversary is the purest version, because the date is fixed and the story is finite.

When the International Committee of the Red Cross marked ten years since the start of the Syria conflict in 2021, they didn't add a section to icrc.org. They built a microsite companion to their report "A Decade of Loss: Syria's Youth After Ten Years of Crisis", profiling five young Syrians whose words carried the weight of a 1,400-person survey of 18-to-25-year-olds across Syria, Lebanon and Germany. ICRC never had to explain its broader mission inside the experience. The stories did that. See the build

An anniversary satisfies the time-bound test before you start. That's rarer than it sounds, and it's why this is the easiest case to make internally.

‍

Use Case 2 — The artist-led documentary: Syria Street and facing.life

A few years earlier, ICRC commissioned something different through the artist Brandon Tauszik. Syria Street wasn't about Syria. It was about a real street in Tripoli, Lebanon, a neighborhood split down the middle, where people who had been neighbors for years found themselves on opposite sides of the country's civil war legacy. Tauszik documented it in cinemagraphs: still photographs with one element of motion, fabric in the wind, steam off a glass of tea. The site loaded that imagery progressively so it held up on a desktop in Geneva and a phone in Beirut. More on the ICRC partnership

Two ICRC microsites, two different jobs. One a ten-year retrospective, the other an artist's portrait of a single street. Same partner, same format choice. Even a humanitarian organization with a sophisticated main website keeps coming back to microsites when the storytelling deserves room.

The same logic produced facing.life, a long-form documentary by Tauszik and journalist Pendarvis Harshaw, funded by a Pulitzer Center grant. It follows eight Californians released from prison after decades inside, and what re-entry actually looks like when the state hands you a $200 debit card, directions to a halfway house and a parole officer to check in with. The site uses cinemagraphs, video, 360-degree VR and text together. Within a year of its April 2022 launch it had drawn 60,000 visitors, won an Anthem Award for Education, Art & Culture, and been profiled by The Guardian, the LA Times, BuzzFeed News, KQED, ARD, the British Journal of Photography, Huck and It's Nice That.

It didn't live inside a publication. It didn't compete with a publisher's house style. It got to be itself.

‍

Use Case 3 — The annual interactive report

Sometimes the report is the product. The data is gathered, the findings are written, and the only thing left is getting it in front of the people who need it.

For years, the people who needed the UN's SDG progress reports received them as documents faxed to a local office every two years. The United Nations Development Programme built SDGs Today to change that: a series of episodic microsites, each drilling into a single Sustainable Development Goal with data design journalists and policymakers actually engage with. Fifty and Fifty built two editions, one on inequality, framed visually as a redacted historical document, and one on health, examining the world's progress on health-related SDGs through the lens of the COVID-19 pandemic. A prior edition of SDGs Today won a Webby.

Inside one microsite, a journalist can stay at the surface with quick stats and headline findings while a researcher goes deep into regional breakdowns and methodology. Each audience finds what it came for without being dragged through the other's version. A static PDF can't do that.

‍

‍

The same logic scales down. The San Diego Foundation had research on a youth mental health crisis in San Diego County and three audiences to reach: school district policymakers who needed to act, donors who needed to see where their money would move, and a community that needed to see itself in the response. Fifty and Fifty built the SDF Youth Report in Webflow so each audience could find what it needed: guides for policymakers, stories for donors, ways to engage for community members.

Here's what makes it interesting. It was designed as a campaign microsite, but the structure is reusable. Build it once with a clear content model, and every Mental Health Awareness Month becomes a content refresh rather than a new project. Short-term doesn't have to mean one-time.

‍

Use Case 4 — The global activation campaign

Some microsites have one job: get a lot of people to do one thing.

The United Nations Environment Programme has built that pattern more times than most organizations. Fifty and Fifty has worked with UNEP on at least six: two editions of World Environment Day, the Global EbA Fund, (the Ecosystem-based Adaptation Fund jointly run by UNEP and IUCN), Beat Waste Pollution, the Biodiversity SDGs Tool, and ActNow / Speak Up while it was live. Each isolated a single theme and built a focused experience around it.

Here's what UNEP figured out that most nonprofits haven't. Choice paralysis kills participation. Ask people to care about everything and you get nothing. Give them one thing they can do, in their own community, in the next 24 hours, with what they already have, and you get tens of thousands of events.

‍

World Environment Day 2022 is the cleanest example. The campaign marked the 50th anniversary of UNEP's founding and of the 1972 Stockholm Conference on the Human Environment, the meeting that put environmental governance on the global agenda. Sweden hosted. The theme, #OnlyOneEarth, was the 1972 slogan brought back fifty years later.

The microsite let visitors pick one action based on their region, whether they were an individual in São Paulo, a government office in Nairobi or a company in Berlin, and commit to it through a form. A live global map showed where every pledge landed. Each commitment generated a custom social graphic, making the visitor part of a visible movement rather than an anonymous form submission. A HubSpot and Webflow integration routed the data back into UNEP's communications.

The numbers:

• 570,000 website visitors
• 4.3 million views of UNEP's video content
• Articles in 166 countries
• 55,000 downloads of the practical action guide
• The number one trending topic on Twitter on June 5
• Over 10,000 events created globally

Campaign figures are UNEP's own, reported at the close of World Environment Day 2022 and recorded in our case study. UNEP published them as a downloadable campaign report that stood online for years. Its public pages have since been restructured and the original PDF is no longer served.

A section of unep.org could never have done that.

NOTE - Another honorable mention in the UNEP microsite library is the Beat Plastic Pollution site, showcasing compelling statistics and what will happen if we don't learn to manage our global waste.

Use Case 5 — The reusable microsite framework

When a nonprofit runs the same kind of program more than once, a curriculum, a training cohort, an annual research focus, the third or fourth iteration doesn't deserve to be rebuilt from scratch. It deserves a framework.

The Pulitzer Center worked this out around its AI Spotlight Series, launched in April 2024 and led by AI accountability journalist Karen Hao. The initial goal was training 1,000 journalists to cover artificial intelligence. By the Pulitzer Center's own count the program trained nearly 3,000 journalists and editors in seven languages across 122 countries, and the curriculum was open-sourced in late 2025 under a Creative Commons license so newsrooms anywhere can run it.

The framework Fifty and Fifty built isn't a one-off campaign site. It's a system. The architecture, content model and templates can be duplicated and re-themed for the next subject. Ocean protection is among the launches Pulitzer is building from the same foundation. Each themed launch pulls in its own content, its own authors, its own events, its own CTAs, while sharing the underlying spine.

That's structurally different from adding categories to your main site. If you run a recurring program and find yourself rebuilding from scratch each cycle, this is what you're missing.

‍

Use Case 6 — The coalition advocacy microsite

The sixth is the rarest, and it might be the most interesting. Sometimes a cause needs a microsite that nobody owns.

When proposed reforms to the National Institutes of Health threatened to merge the National Eye Institute back into a broader neuroscience umbrella, the vision research community needed a coordinated response. The National Eye Institute had been created as an independent body in 1968 precisely because vision science wasn't getting enough attention inside that umbrella.

No single organization could lead the campaign alone. The American Academy of Ophthalmology, the American Academy of Optometry, the Association for Research in Vision and Ophthalmology, the Association of University Professors of Ophthalmology and the National Alliance for Eye and Vision Research each had their own brands, donor bases and communications priorities. What they shared was a cause.

What emerged is See What Matters, a microsite built as neutral ground under one campaign mark, where all five partners share the storytelling, the toolkit and the call to action. The Alliance for Eye and Vision Research leads it, funded by Research to Prevent Blindness, but no single organization owns the brand. Visitors get the case for the institute's independence, the data behind the threat as the campaign sets it out (60% of Americans over 40 experience vision issues; 15 million Americans are visually impaired; the projected annual economic impact reaches $400 billion by 2050), and a Contact Congress CTA that routes directly to legislative action.

Two things make it work. Shared neutral ground means politicians see an entire field, not one organization with an interest. And a downloadable toolkit, with a campaign deck, social copy, creative assets and a printable handout, lets each partner run the campaign through their own channels without rebuilding it.

Coalitions are how most large advocacy work actually happens. The microsite is the format that lets a coalition look unified online.

When NOT to build a microsite — and how to build one that lasts

For everything microsites do well, there's an equal list of how they fail. Three show up over and over.

Putting microsite content on the main site. Time-bound content, campaign pages and one-off interactive features clog your main site's structure, dilute its core identity, and confuse the SEO signals search engines use to understand what your organization is about. As LLM-driven retrieval becomes more of how donors and journalists find nonprofits, that confusion compounds.

Failing to plan the lifecycle. Microsites work because they're time-bound, and time-bound requires a decision: retire, redirect or evolve. Most organizations never make it. The content goes stale, the contact form breaks, and the URL becomes a 404 two years after launch. Decide at launch.

Putting permanent content on a microsite. Your blog, your thought leadership, your evergreen resources belong on the main site where they compound across years and rank in search. A microsite is the wrong home for anything not supposed to end.

The counter-example to all three is TUMO Armenia. TUMO is a free after-school program for teenagers covering design, technology, animation and music. It started in Yerevan in 2011 and by TUMO's own count has served over 60,000 young people. On its tenth anniversary in September 2021 the organization launched armenia.tumo.org, a $60 million campaign to put a TUMO within reach of every teenager in the country: 16 full-scale hubs in major cities and 110 transportable TUMO Boxes for remote communities. The design vision that anchored the build was getting a hub or box within 30 minutes of every child in Armenia. See the build

That microsite hasn't sunset, because it was never designed to. Each year the campaign adjusts. Donors in Armenia choose which location to fund. Major donors get a different flow with the option to sponsor a whole facility. Recurring donors receive a piece of jewelry made from the building materials of the facilities going up, a physical thank-you tying the giver to the place. Tests run year-round. The content updates. The campaign compounds.

Microsites built to last aren't different in format from microsites built to sunset. They're different in operating discipline. Someone owns the maintenance. The content has a refresh cadence. Treat it as a living tool rather than a project that ended at launch, and it earns its keep for years.

Why nonprofit microsites are worth it

A microsite is not a smaller website. It's a different format for a different kind of moment. An anniversary, an annual report, a global activation, a recurring program, a coalition push. These are the moments microsites do better than anything else.

The cost has collapsed. No-code tools like Webflow let teams ship in weeks rather than quarters. Donation engines like Donately embed in a microsite about as easily as a YouTube video, which means your campaign can take a recurring gift the day it launches.

And in a no-click era, where retrieval engines pull stories out of context, a microsite is one of the few places left where a nonprofit can tell a whole story on its own terms, in a setting designed for a human reader rather than a crawler. Your main site has to be ready for SEO and AEO. Your microsite gets to be ready for the human.

You already know which moment this is for. If you're sitting on a 2027 anniversary, a 2026 annual report, a coalition push or a recurring program that has never had a proper home, this is the format. Reach out to Fifty and Fifty and we'll talk through what your moment deserves.

Frequently Asked Questions

What is a nonprofit microsite, and how does it differ from a main website?

A self-contained website with its own URL, focused on one campaign, audience or moment. Unlike a section of the main site, it has its own navigation, its own voice and one conversion goal, so the moment gets undivided attention instead of competing with everything else you publish.

Why should a nonprofit use a microsite instead of a standard landing page?

A landing page is built around one conversion on one page. A microsite is built around a story, with multiple pages and deeper interactivity. The ICRC's Decade of Loss profiled five young Syrians in depth. When the moment needs that kind of depth, layered data or multi-audience navigation, a landing page is too thin.

What are the top website builders for nonprofit microsites?

Webflow is the strongest default for custom builds, pairing editorial flexibility with lightweight hosting and direct integration with the donation engines, CRMs and marketing automation tools nonprofits already use. WordPress and Squarespace work for simpler microsites, trading some speed and interactive flexibility.

How does a nonprofit microsite collect donations?

Most embed a donation engine rather than building checkout from scratch. A tool like Donately drops into a Webflow or WordPress microsite the way you'd embed a video, so the campaign can take one-time or recurring gifts on day one. Keep the form under six fields; abandonment climbs fast past that.

Can a nonprofit reuse a microsite for an annual fundraising event or conference?

Yes, and it's one of the strongest cases for the format. The structure stays consistent year over year and only the content changes. The Pulitzer Center's AI Spotlight framework is one production example, now running in 7 languages. The SDF Youth Report is another at community-foundation scale, refreshed every Mental Health Awareness Month. Built once with a clear content model, each year is a refresh rather than a rebuild.
