If your organization is a registered 501(c)(3), your website is doing more work than a typical business site. It's not just attracting customers. It's building trust with donors, satisfying grant reviewers, recruiting volunteers, communicating your mission to the public, and in many cases qualifying you for programs like the Google Ad Grant. (We covered the unique design challenges in depth in faith-based nonprofit web design: what makes it different.)

That's a lot of jobs for one website. And most nonprofit sites we see aren't built to handle all of them. They were designed like a business site or thrown together quickly when the organization launched, and they've been patched and updated unevenly ever since.

After working with over 80 churches and nonprofit organizations, we've developed a clear picture of what a 501(c)(3) website actually needs to rank in search engines, build trust with every audience, and meet the compliance standards that grant programs require.

Here's the complete checklist. Use it to audit your own site, or hand it to whoever manages your web presence.

Foundation: The Non-Negotiables

These items should be on every nonprofit website, no exceptions. If any of them are missing, fix them first.

Clear Mission Statement on the Homepage

Your mission statement should be visible within the first screen of your homepage without scrolling. Not buried in an "About" page. Not hidden behind a slider. Right there, front and center, in plain language that a stranger can understand in one read.

A grant reviewer will look for this. A potential donor will look for this. A first-time visitor trying to figure out what your organization does will look for this. Make it impossible to miss.

Contact Information on Every Page

Your phone number, email address, and physical address (or service area if you don't have a public office) should be accessible from every page. The footer is the standard place. Your Contact page should also include a simple form.

This isn't just about convenience. Google uses consistent contact information as a trust signal for local search rankings. And grant programs like the Google Ad Grant require that your site displays "adequate contact information."

HTTPS Security Certificate

Your site must use HTTPS (the padlock icon in the browser bar). This is a Google ranking factor, a Google Ad Grant requirement, and a basic trust signal. Visitors see a "Not Secure" warning on HTTP sites in most browsers. That's an instant credibility killer for an organization asking people to trust you with donations.

Most hosting providers offer free SSL certificates through Let's Encrypt. If your site still runs on HTTP, this is the first thing to fix. (This is one of the items we flag in our church website audit checklist — it's a quick fix with outsized impact.)

Mobile-Responsive Design

More than half of your visitors are on phones. If your site doesn't work on mobile, every other item on this checklist is irrelevant because people aren't staying long enough to see any of it.

Mobile responsiveness means the layout adapts to the screen size. Text is readable without zooming. Buttons are tappable. Navigation works with a thumb. Images resize properly. Test your site on your own phone and on a friend's phone. If anything feels awkward, it needs to be fixed.

Trust and Credibility

Nonprofits live and die by trust. Your website is where most people form their first impression of whether your organization is legitimate, competent, and worth supporting.

About Page with Real People

Your About page should include the names, roles, and photos of your leadership team. Stock photos don't count. People give money to people, not logos. If a donor can see who's leading the organization and read a short bio, they're far more likely to give.

If you have a board of directors, list them. If you have key staff, feature them. Transparency builds confidence.

Financial Transparency

Donors and grant reviewers want to know that their money is being used responsibly. The best nonprofit websites include:

An annual report or impact summary (even a simple one-page version)
A link to your 990 filing (available on GuideStar/Candid) or a direct download
A statement about how donations are used, ideally with percentages (e.g., "87 cents of every dollar goes directly to programs")

You don't need to publish a full audit. But the more transparent you are, the more confident people feel supporting you.

Testimonials and Impact Stories

Data is good. Stories are better. Include at least one or two real stories from people your organization has served, volunteers who've had meaningful experiences, or community partners who can speak to your impact.

These stories serve double duty: they build emotional connection with potential donors, and they give search engines rich, unique content that helps your pages rank.

EIN and Tax-Deductible Giving Statement

Somewhere on your site, typically your Giving page or footer, include your EIN (Employer Identification Number) and a simple statement that donations are tax-deductible. This is a small detail that signals professionalism and makes the giving decision easier for donors who want documentation.

SEO and Search Visibility

Your website can be beautiful and trustworthy and still invisible if search engines can't find it. These items ensure that people searching for organizations like yours can actually discover you.

Google Business Profile (Claimed and Verified)

If you haven't claimed your Google Business Profile yet, stop reading and do it now. This is the single most impactful thing you can do for local search visibility. It's what determines whether you show up in the map results when someone searches for nonprofits, churches, or community organizations in your area.

Make sure your profile includes accurate hours, address, phone number, website URL, a description of your organization, and recent photos.

Title Tags and Meta Descriptions on Every Page

Every page on your site should have a unique title tag (the text that appears in the browser tab and Google results) and a meta description (the short summary below the title in search results).

For a nonprofit, your title tags should include your organization name and a keyword that describes what you do. For example: "RestoreOne | Foster Care Support in Hartford, CT" is far better than just "Home."

Local Keywords in Your Content

If you serve a specific geographic area, your website should mention that area naturally throughout your content. Your homepage, About page, and service/program pages should all reference the cities, towns, or regions you operate in.

This isn't keyword stuffing. It's basic local SEO. Google needs to understand where you are and who you serve in order to show you to people searching in that area.

Blog or Resource Section

Nonprofit websites that publish regular content rank significantly better than those that don't. You don't need to publish weekly. Even one post per month about your work, your community, your impact, or your area of expertise builds topical authority over time.

Content ideas for nonprofits: volunteer spotlights, program updates, community impact stories, guides related to your mission area, event recaps, and answers to frequently asked questions.

Fast Page Speed

The same speed standards that apply to any website apply to yours. Aim for a load time under 3 seconds on mobile. Large images, outdated platforms, and excessive plugins are the usual culprits.

Run your site through Google PageSpeed Insights and address any red flags. Speed affects both your search rankings and your visitor retention. If your site is consistently slow, it may be a sign you need a full redesign rather than incremental fixes.

Google Ad Grant Compliance

If you're a 501(c)(3), you're likely eligible for the Google Ad Grant, which provides $10,000 per month in free Google Ads. But Google has specific website requirements that many nonprofits don't realize until their application gets rejected.

Substantial Website Content

Google requires that your site has "substantial and unique content." That means multiple pages with real, original text. A single-page site or a site with mostly stock content won't qualify. Your site should have at minimum a homepage, about page, programs/services page, contact page, and ideally a blog or resources section.

No Broken Links or Error Pages

Google checks for broken links and 404 errors as part of the Ad Grant review process. Run a broken link checker across your site and fix anything that's dead. This is also good practice for SEO in general.

Clear Calls to Action

Your site should have obvious next steps for visitors. "Donate," "Volunteer," "Learn More," "Contact Us." Google wants to see that your site provides a clear user experience and isn't just a placeholder.

Mission-Focused Content (Not Commercial)

The Google Ad Grant is for nonprofits, not businesses. If your site reads like a sales page or promotes commercial products, it may be disqualified. Keep your content focused on your mission, your impact, and the communities you serve.

The Giving Experience

For most nonprofits, online giving is a critical revenue stream. Your website should make giving easy, trustworthy, and frictionless.

Prominent "Give" or "Donate" Button

Your giving call to action should be visible in your main navigation on every page. Don't bury it in a submenu. Don't call it something clever that people have to decipher. "Give" or "Donate" in the top navigation is the standard.

Simple Donation Process

The fewer clicks between "I want to give" and "I gave," the better. If your donation process requires creating an account, filling out a long form, or navigating away from your site to a platform that looks completely different, you're losing donors at every step.

Embedded giving forms that match your site's design convert significantly better than external redirect links.

Recurring Giving Option

Make it easy for donors to set up recurring monthly gifts. Most modern giving platforms support this, but make sure the option is clearly visible during the giving process, not hidden behind a checkbox.

Your Action Plan

You don't have to tackle this entire checklist in a week. Here's how to prioritize:

This week: HTTPS, mobile check, Google Business Profile, and contact info on every page. These are the bare minimum for credibility and visibility.

This month: Mission statement on homepage, About page with real photos, title tags and meta descriptions, and a "Give" button in your nav.

This quarter: Financial transparency section, blog or resources page, Google Ad Grant application, speed optimization, and impact stories.
