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

TL;DR

• A nonprofit microsite is a self-contained website with its own URL, focused on a single campaign, audience, or moment — built to do one job that would dilute the main site if embedded there.
• It's different from a landing page (too thin to carry a story) and different from a section of the main site (too embedded to feel like its own thing).
• Three signals it's the right format: time-bound start and end, a single specific call to action, and a story that would lose its weight inside a main site's navigation.
• Six campaign formats microsites do better than anything else: anniversary commemorations, artist-led documentary storytelling, annual interactive reports, global activation campaigns, reusable program frameworks, and coalition advocacy.
• UNEP's World Environment Day 2022 is the clearest proof of scale — a custom microsite with a HubSpot and Webflow integration anchored a campaign that reached 570,000 site visitors and articles in 166 countries.
• Microsites fail when there's no sunset plan, no integration with the main CRM, or no single owner for ongoing maintenance. TUMO Armenia is the counter-example — a $60 million campaign that compounds year over year because the team treats it as a living tool, not a one-time launch.
• The cost has collapsed. No-code tools have turned what used to be six-figure builds into something a mid-sized nonprofit can ship for a fraction.

The first instinct, when a nonprofit is staring down an anniversary, an annual report, or a campaign with a deadline, is to find space on the main site. Add a section. Drop a banner. Embed it somewhere 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 one thing to do. That's a microsite. And the nonprofits that figure this out before their next big moment tend to outrun the ones still arguing with their CMS.

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 keep federal funding for vision research alive. Seven different jobs. Same 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. It runs on its own. 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 often confuse it with.

A landing page is one page with one CTA. A microsite has multiple pages, interactive experiences, a story arc, and usually more than one path through the content. If your moment needs storytelling depth, layered data, or multi-step engagement, a landing page is too thin.

A section of the main site is embedded inside everything else. Your campaign banner shares space with your About page, your blog, your annual report, your donate button. The microsite gets pulled in three directions before the visitor even reads the headline. If your moment needs undivided attention, a section is too embedded.

Three signals tell you a microsite is the right format. First, the work is time-bound — it has a start and end date, even if "end" means "rolls into next year's edition." Second, there's a specific CTA — fund this thing, sign up for this event, take this one action. Third, the story or data or experience would lose its weight if it had to share space with everything else your organization does.

If you've got all three signals, you've got a microsite. If you've got none of them, you've got main-site content trying to escape its home, and the better fix is to make the main site better.

Pro-Tip: Microsite vs. 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 a few 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, not bolted on 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 from visitors.
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 platform. Webflow for custom, interactive builds; WordPress or Squarespace for simpler ones.
4. Wire integrations first. Donation engine (a tool like Donately), CRM, and marketing automation, so data routes back to the main systems.
5. Build the story, not just the page. Design the pacing, visuals, and path for the human reader.
6. Plan the lifecycle before launch. Assign the owner and decide 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. They need their own house, their own pacing, their own visual language. The format that delivers all three is the immersive storytelling microsite — and the clearest version of it is the anniversary.

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" — an experience profiling five young Syrians in detail, whose words and stories carried the weight of a 1,400-person survey of 18-to-25-year-olds across Syria, Lebanon, and Germany. ICRC didn't have to explain its broader mission inside the experience. The stories did that. See the build →

An anniversary is the purest case for the format. The date is fixed, the story is finite, and the moment has a natural end — which is exactly the time-bound test, satisfied before you start.

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

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

Two ICRC microsites. Two different jobs. One a ten-year retrospective. The other an artist-led portrait of a single street. Same partner, same format choice. That tells you something: even one humanitarian organization with a sophisticated main website keeps coming back to microsites when storytelling deserves room to breathe.

The same logic applied when Fifty and Fifty designed and built facing.life, a long-form documentary microsite by Brandon Tauszik and journalist Pendarvis Harshaw, funded by a Pulitzer Center grant. It follows eight Californians released from prison after decades inside — 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, facing.life had drawn 60,000 visitors, won an Anthem Award for Education, Art & Culture, and been profiled by The Guardian, LA Times, BuzzFeed News, KQED, ARD, the British Journal of Photography, Huck, It's Nice That, and others. It didn't live inside a publication. It didn't compete with a publisher's house style. It got to be itself.

The connective thread across all three — the Decade of Loss anniversary, Syria Street, and facing.life — is worth naming: when storytelling itself is the work — when the photography, the pacing, the design, the experience are what the audience came for — a microsite is the only format that doesn't get in your way.

Use Case 3 — The annual interactive report

The third use case is what happens when the report is the product. When the data has been gathered, the findings are written, and the only thing left is to put it in front of the people who need it.

In the UN's case, the people who needed the SDG progress reports used to receive them as documents faxed every two years to a local office. The United Nations Development Programme built SDGs Today to change that — a series of episodic microsites, each one drilling into a single Sustainable Development Goal with the kind of interactive data design that journalists, policymakers, and researchers 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. That tells you what the format unlocks. Inside one microsite, a journalist can move at the surface level — quick stats, big-picture findings, executive summary — while a researcher can go deep into the data, the regional breakdowns, the methodology. Each audience finds what they came for without forcing the other audience through it.

What both UNDP editions got right is the marriage of statistics and story. The numbers anchor the credibility; the stories anchor the meaning. Most of the work nonprofits do is relatively complex, and the format has to find the line between complexity and simplicity. A static PDF can't do that. A section of the main UNDP site can't do that. A microsite — built around the report as the product — can.

The same logic scales down. The San Diego Foundation had research on a youth mental health crisis in San Diego County. They had three audiences they needed to reach: school district policymakers who needed to act, donors who needed to see where their money could move the needle, and the broader community that needed to see themselves in the response. Fifty and Fifty built the SDF Youth Report in Webflow, designed so each audience could find what they needed — guides for policymakers, stories for donors, ways to engage for community members — without all of them landing on the same content.

Here's the thing that makes the SDF Youth Report bridge two use cases. It was designed as a campaign microsite, but the structure is reusable. You build it once with a clear content model. Each year — every Mental Health Awareness Month, every back-to-school season — you refresh the content, add the new data, update the year. The microsite becomes a tool that compounds. 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 microsites: 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 one isolated a single environmental theme — restoration, adaptation, plastic, biodiversity, individual action — and built a hyper-focused experience around it.

Here's what UNEP figured out that most nonprofits haven't: choice paralysis kills participation. When you ask people to care about everything, you get nothing. When you give them one thing they can do — in their own community, in the next 24 hours, with the materials they already have — you get tens of thousands of events, hundreds of thousands of pledges, and millions of conversations.

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 in the first place. Sweden hosted. The theme, #OnlyOneEarth, was the same slogan as 1972, brought back fifty years later. The microsite let visitors pick one specific environmental 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 an interactive form. A real-time global map showed where every pledge was landing. A custom social graphic was generated for each commitment, making the visitor part of the visible movement instead of an anonymous form submission. A HubSpot and Webflow integration captured the data and routed it back into UNEP's communications.

The numbers tell the story:

• 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 #1 trending topic on Twitter on June 5
• Over 10,000 global events created

Campaign figures are UNEP's own, reported at the close of World Environment Day 2022 and recorded in our case study.

That's what a microsite can do that a section of unep.org never could. 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 usually doesn't deserve to be rebuilt from scratch. It deserves a framework.

The Pulitzer Center figured this out around its AI Spotlight Series, launched in April 2024 and led by AI accountability journalist Karen Hao. The initial goal was to train 1,000 journalists on how to cover artificial intelligence. By the Pulitzer Center's count the program ended up training 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 adapt and run it.

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

That's structurally different from "build categories on your main site." A reusable microsite framework lets the next thematic launch have its own brand expression, its own paid media push, its own audience flow — without forcing every choice to fit inside the main site's information architecture. If your organization runs a recurring program — an annual conference, a yearly research focus, a quarterly grant cycle — and you find yourself re-platforming from scratch each cycle, the framework approach is what you're missing.

Use Case 6 — The coalition advocacy microsite

The sixth use case 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 — an independent research institute created in 1968 specifically because vision science wasn't getting enough attention inside a broader neuroscience umbrella — back into exactly that broader umbrella, the vision research community needed a coordinated response. But 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, their own donor bases, their own communications priorities. What they shared was a cause.

The campaign that emerged is See What Matters — a microsite built as a neutral container under one campaign mark (#SeeWhatMatters), 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 vision research'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 of vision conditions reaches $400 billion by 2050), and a Contact Congress CTA that routes directly to legislative action.

What makes this work, where individual partner sites couldn't, is the shared neutral ground. The goal is the rising tide that lifts all boats — when politicians and policymakers see that the entire vision research field, not just one organization, considers this a fight worth having, the policy case gets stronger. And practically, the downloadable toolkit (campaign overview deck, social copy, creative assets, impact statements, printable handout) lets each partner plug the campaign into their own communications without rebuilding it from scratch.

Coalitions are how most large advocacy work actually happens. The microsite is the format that lets coalitions 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 failure modes show up over and over.

The first is putting microsite content on the main site. This is the most common mistake, and it does real damage. Time-bound content, campaign-specific landing pages, and one-off interactive features clog the main site's information architecture, 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.

The second is failing to plan for the lifecycle. Microsites work because they're time-bound. But "time-bound" requires a decision: retire it, redirect it, or evolve it. Most organizations don't make that decision — they let the microsite drift, the content go stale, the contact form break, the URL become a 404 two years after launch. The fix is to decide at launch what the post-launch plan is.

The third is putting permanent content on a microsite. Your blog, your thought leadership, your evergreen resources — those belong on the main site, where they can compound across years and rank in search. A microsite is the wrong home for things that aren't supposed to end.

The counter-example to all three failure modes is TUMO Armenia. TUMO is a free, after-school education program for teenagers — design, technology, animation, music — that started in Yerevan in 2011 and, by TUMO's own count, has since served over 60,000 youths. In September 2021, on TUMO's tenth anniversary, the organization launched armenia.tumo.org, an online campaign to bring TUMO closer to every teenager in Armenia: 16 full-scale Hubs in major cities and 110 transportable TUMO Boxes for remote communities. The original design vision that anchored the build was getting a TUMO Hub or Box within 30 minutes of every child in the country. See the build →

The microsite hasn't sunset, because it wasn't designed to. Each year, the campaign adjusts. Donors in Armenia can choose which specific location to fund. High-net-worth donors get a different flow with the option to sponsor an entire facility. Recurring donors receive a piece of jewelry made from the building materials of the facilities being constructed — a physical thank-you that ties the giver directly to the place. A/B tests run year-round. The content updates. The campaign compounds.

The lesson is that 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. The donation flows evolve as the audience does. Treat the microsite like a living tool, not a project that ended at launch, and it earns its keep over 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 of building one has collapsed. No-code tools like Webflow let teams ship in weeks instead of quarters. Frictionless donation engines like Donately can be embedded in a microsite as easily as embedding a YouTube video — a five-minute setup that means your campaign microsite can take a recurring gift the day it launches.

And in an AI-driven, no-click era — where the open web is increasingly broken into fragments by retrieval engines that pull stories out of context — a microsite is one of the few places left where a nonprofit can tell a story holistically, on its own terms, in a setting designed for the human reader instead of the bot crawler. Your main site has to be ready for SEO and AEO. Your microsite gets to be ready for the human.

If you're sitting on a 2027 anniversary, a 2026 annual report, a coalition push, or a recurring program that's never gotten a proper home — this is the format. Reach out to Fifty and Fifty to talk through what your moment deserves.

Frequently Asked Questions

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

A nonprofit microsite is a self-contained website with its own URL, focused on a single campaign, audience, or moment. Unlike a section of the main site, a microsite has its own navigation, its own voice, and one specific conversion goal — which lets the moment carry undivided attention without competing with the rest of the organization's online presence.

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

A landing page is built around a single conversion in a single page. A microsite is built around a single story or experience, with multiple pages, deeper interactivity, and longer time-on-site. When the moment needs storytelling depth, layered data, an interactive pledge mechanic, or multi-audience navigation, a landing page is too thin to carry the weight.

What are the top website builders for nonprofit microsites?

Webflow is the strongest default for custom builds because it pairs editorial flexibility with lightweight hosting and direct integration with the donation engines, CRMs, and marketing automation tools nonprofits already use. WordPress and Squarespace can work for simpler microsites, with the tradeoff being longer load times and less flexibility for custom interactive elements.

How does a nonprofit microsite collect donations?

Most fundraising microsites embed a donation engine rather than building checkout from scratch. A tool like Donately drops into a Webflow or WordPress microsite the same way you'd embed a YouTube video — a few lines of code — so the campaign can accept one-time or recurring gifts the day it launches. Keeping the form short, ideally under six fields, reduces abandonment, which matters most on campaign microsites where the visitor has already arrived, ready to give.

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

Yes — reusable microsite frameworks are one of the strongest cases for the format. The structure (registration, agenda, speakers, sponsors, donation flow) stays consistent year over year; only the content changes. The Pulitzer Center's AI Spotlight framework is one production example. The SDF Youth Report shows the same logic at community-foundation scale — a microsite that runs every Mental Health Awareness Month, refreshed with new data each cycle. Built once with a clear content model, each year's edition becomes a fast refresh rather than a new project.
