Best hashtags for nonprofits: tags that reach donors and volunteers

October 15, 2026

What are the best hashtags for nonprofits? The ones browsed by people who could give, volunteer or share: people who already care about your cause, people who live where you work, and people looking for a way to help this week. Tags like #nonprofit and #charity look like the obvious choice, and they are mostly read by other organisations, fundraising consultants and agencies selling to both. Instagram now caps a post at five hashtags, so each one has to point at a supporter who would act on this exact post. This guide shows how to build a pool of nonprofit tags, how to pick five per post, and how to check each month which ones bring donors and volunteers.

Why nonprofit hashtags work differently

A charity is not selling a product, so the reader you want is not a shopper. A supporter is someone who cares about the problem you work on, often close to where you work, and who is waiting for a reason and a way to help. That changes which tags earn their place:

• The cause is how supporters search. A person who fosters dogs follows #adoptdontshop, not #nonprofitorganization.
• Sector tags reach the sector. #nonprofitlife, #nonprofitmarketing and #charityworker gather people who work in charities. Useful for hiring and peer advice, weak for donations.
• Place is your strongest filter. Most volunteers, and many donors, give near home. A city or neighbourhood tag reaches people who can actually show up.
• Campaigns are short-lived, the cause is not. A fundraiser tag is worth most in its campaign weeks. Your organisation’s own tag is worth something on every post for as long as you publish.

For the general method (broad, mid and niche tags, with a worked example), see best hashtags for Instagram. If you run a social enterprise that also sells something, best hashtags for small business adds the customer angle. This article applies both to charities, foundations and community groups.

The best hashtags for nonprofits, by type

Every organisation, from a volunteer-run food pantry to a national charity, draws on the same six kinds of tag. What changes from post to post is the mix.

Cause tags put a post in front of people who already care about the problem. Place tags reach people who can volunteer, attend or drop off a donation. Action tags match what the post asks for. Campaign tags join a conversation that is busy for a few days a year. Your own tag gathers everything you post and is what supporters use when they share your work.

Five tags is the ceiling, so the pool matters more than the post. Keep a pool per group and choose five for each post. A block of thirty generic charity tags pasted under every photo no longer works at all.

How to build your nonprofit hashtag set

You need the Instagram app, your list of programmes and campaigns, and a notes file. Plan on about half an hour.

1. Write one sentence about who you want to reach. “People in Bristol who could give two hours a week at our food bank.” “Cat owners who would sponsor a rescue for a month.”
2. List your cause words from narrow to wide. Start from the most specific name for what you do, then its parent cause. #seniorcatrescue before #animalrescue, #literacyvolunteers before #education.
3. List your place words. City, region, neighbourhood, and the way locals write them.
4. Open each candidate tag in the app. Are the recent posts about your cause? Does the tag belong to something else, such as a brand, a political campaign or a different meaning of the same word? Drop anything that means something else.
5. Check how busy each tag is. A tag with a handful of posts in the last month has almost no audience. One flooded every minute buries you. Keep the ones with steady recent posts you could realistically stand out in.
6. Read your comments and messages for words. “How do I sign up to help on Saturdays?” “My mum used your service last winter.” Those words point to cause and action tags you had not thought of.
7. Look at what organisations one step ahead of you tag. Pick a few charities in your cause with an audience a bit bigger than yours. Treat their tags as candidates, never a finished set, and check each one yourself.
8. Make your own tag and use it on every post. Put it in your bio, on event signs and on thank-you cards, so supporters use it when they share.
9. Save the pool in groups, one per kind of tag, so choosing five for a post is a quick pick across groups.

If you are not sure how to search a tag or read its page, how to search hashtags on Instagram covers the phone and the web. For a campaign tag, how to create your own hashtag shows how to check nobody else already uses it.

Charity and campaign hashtags: when to use them

Days like #givingtuesday (the Tuesday after US Thanksgiving) and awareness days for your cause pull a lot of attention into one tag for a short time. They are worth a slot only when the post genuinely belongs to that moment.

• Use them in the days around the event, on posts that ask for the thing the day is about.
• Expect a crowd. Thousands of organisations post under the same tag that week. Pair it with a cause tag and a place tag so the post also reaches people who are not scrolling the big tag.
• Give your own appeal a tag of its own, short and spelled the way people would say it. It lets you see every post about the appeal in one place, including the ones supporters make.
• Retire a campaign tag once the campaign ends. Keep it in your notes for next year rather than in every post.

Choose different tags for each kind of post

A volunteer call, a thank-you post and an impact story are found by different people. One fixed block under every post wastes most of your five.

Rotate within each group. With eight cause tags in the pool and two per post, each tag gets tried on several posts, and you learn which ones actually find supporters. For Reels in particular, best hashtags for Instagram Reels explains how to match the five to what the video shows.

Common mistakes nonprofits make with hashtags

• Spending the five on sector tags. #nonprofit, #charity, #nonprofitorganization and #givingback are read mostly by other organisations. Use one at most, and only when the post is meant for them.
• Leaving out the place. A volunteer call with no city tag reaches people who live too far away to come.
• Joining a cause tag without reading it. Some cause tags are used for arguments, merchandise or a campaign you would not want to stand beside. Open the tag first.
• Keeping a campaign tag forever. An appeal tag belongs to its campaign weeks.
• Copying a big charity’s tags. Their tags work because of their audience. They will not create one for you.
• Unreadable joined words. Capitalise each word in long tags (#FoodBankVolunteers) so people and screen readers can read them.

How to tell which tags bring support

Instagram shows this on a professional (business or creator) account. Open a post, tap View insights, and see how people found it. Then once a month:

1. List your last 15 to 20 posts and the tag groups each one used.
2. Note which posts reached people who do not follow you, and which earned saves, shares, profile visits or link taps.
3. Compare with your own records: volunteer sign-ups and donations that came in the days after each post.
4. Keep the groups that keep appearing on the posts that did well. Replace tags that never do.

Judge a tag by what supporters do, not by views. A tap on the donate link, a volunteer form filled in or a share to a story means the tag reached someone who might help. A thousand passing views from other charities do not fill a rota.

When the manual way is enough

For one organisation posting a few times a week about one cause in one place, the routine above is all you need. It is free, it takes half an hour, and you know your supporters better than any list.

It stops being enough when:

• you run social for several programmes or branches, each with its own cause and place;
• you are planning a campaign and want to compare many candidate tags at once instead of opening each page;
• you want to see which local creators keep posting under your cause tags, to find ambassadors or partners (see how to find influencers on Instagram);
• you want the research written down so a new volunteer can repeat it next year.

A faster way to plan the research

The slow part is deciding what to look at: which tags, how far back and what to compare. Hashtag Ninja takes that as a sentence. You write something like “hashtags an animal rescue in Manchester should use to find foster volunteers”, and the free planner returns a research plan: the tags to look at, how many posts per tag, over what window, and the assumptions it made. You can correct an assumption, such as the wrong cause or place, before relying on it. The planner needs no account.

Running the plan, meaning collecting the posts and returning a written report and a CSV, is open on the 500 rows every account starts with. The pricing page says what more rows cost. The plan on its own still replaces the first step of the routine above, since it is the tag list and checklist you would otherwise write by hand.

A short checklist

• One sentence describing the supporter you want to reach.
• A pool in six groups: cause, place, action, campaign, sector, your own.
• Five per post, chosen for that post.
• A different mix for volunteer calls, appeals, impact stories, events and thank-yous.
• Every tag opened and read before you use it.
• A monthly look at insights beside your sign-ups and donations, keeping the tags that bring action.

Start with the narrowest honest name for your cause and the place you serve. That alone puts you ahead of every account pasting #charity under every post.
