# GivingTuesday Social Media Posts That Use Social Proof

38.1 million people took part in GivingTuesday 2025 and 19.1 million gave money. Nine posts that show real people taking part, with the evidence and its limits.

## Key takeaways
- 38.1 million people took part in GivingTuesday 2025 in the U.S., but only 19.1 million made a financial gift, according to GivingTuesday's own estimate.
- Volunteering on the day grew 20% to 11.1 million people and speaking out for causes grew 26% to 20.9 million, while the number of people giving money grew only 3% (GivingTuesday).
- In a 2025 meta-analysis of 113 samples covering 100,469 people, social norms were linked to giving at r = .18, and the link was strongest when the norm referred to friends and family (r = .39, against r = .12 with no clear referent).
- The same meta-analysis found no significant effect in preregistered studies, so treat social proof as a reasonable bet, not a proven effect, and never inflate a count to make it stronger.
- Nine posts across three phases, three before the day, three during, and three after, can show real supporters taking part, invite people to share with their own friends, and thank everyone by the next morning.

The best GivingTuesday social media posts show real people taking part, because research on social norms finds their link to giving is strongest when the example comes from a reader's own friends and family. About 38.1 million people in the U.S. took part in GivingTuesday 2025, but only 19.1 million made a financial gift, according to [GivingTuesday's 2025 results](https://www.givingtuesday.org/blog/2025-results/). That leaves a large group who were paying attention to the day and did not give money. Social posts reach that group, and research on social norms, meaning people's sense of what others around them do and approve of, suggests that showing them real participants is a reasonable way to invite them in.

## Who takes part in GivingTuesday without giving money?

GivingTuesday counts several kinds of participation, and in 2025 the ones that grew fastest were not donations. The GivingTuesday Data Commons, which estimates the day from more than 50 data partners, reported these U.S. figures for December 2, 2025:

GivingTuesday 2025 participation in the U.S., by kind, with change from 2024 (GivingTuesday Data Commons estimate)

| Kind of participation | People | Change from 2024 |
| --- | --- | --- |
| Took part in any way | 38.1 million | +6% |
| Spoke out for causes | 20.9 million | +26% |
| Gave money | 19.1 million | +3% |
| Gave goods | 13.5 million | +4% |
| Volunteered | 11.1 million | +20% |

**38.1M vs 19.1M** — people who took part in GivingTuesday 2025 in the U.S. in any way, against people who gave money ([GivingTuesday, 2025 results](https://www.givingtuesday.org/blog/2025-results/))

The categories overlap, since one person can volunteer and give, so the rows do not add up to the total. The pattern still matters for social posts. Speaking out grew 26% and volunteering grew 20%, while giving money grew 3%. Many people who engage with the day do it by sharing or showing up, and sharing is what social media makes easy. A post that asks those people to share can reach their friends, and friends are the reference group that the research below found most persuasive.

## Does social proof work in GivingTuesday social media posts?

Social proof is the tendency to follow what other people are seen doing. The most complete recent evidence on it in giving is a meta-analysis, a study that pools results from many earlier studies (here, a three-level meta-analysis of 257 effect sizes, mixing experiments and correlational studies), by Cassandra Chapman, Jessica Spence, Lucas Dixon, Aimee Smith, and Matthew Hornsey, published in 2025 in [Personality and Social Psychology Bulletin](https://doi.org/10.1177/01461672251383996). It combined 113 independent samples covering 100,469 people in 22 countries and found an overall correlation of r = .18 between social norms and charitable giving. A correlation runs from -1 to 1, where 0 means no relationship and 1 a perfect positive one, so .18 is a real but modest link, and a correlation alone does not show that norms cause the giving.

Who the norm is about made the largest difference. When the norm referred to the person's friends and family, the correlation was r = .39. When it had no clear reference group, it was r = .12, and when it referred to some other group the person belonged to, it was r = .14. Norms about what others approve of (injunctive norms, r = .25) were more closely linked to giving than norms about what others actually do (descriptive norms, r = .15). The authors suggest that peer-to-peer approaches, in which supporters ask their own friends, may be where norms help most.

**r = .39 vs .12** — link between social norms and giving when the norm referred to friends and family, against no clear reference group, in a 2025 meta-analysis of 100,469 people ([Chapman et al., Personality and Social Psychology Bulletin (2025)](https://doi.org/10.1177/01461672251383996))

> **What the social proof evidence does not show**
>
> The same meta-analysis found that preregistered studies, the ones that publish their plan before collecting data, showed no significant link between norms and giving (r = .03), while studies that were not preregistered did (r = .21). Published studies found a link (r = .21) and unpublished studies did not (r = -.04). Norms were also more weakly linked to giving in online studies (r = .12) than offline ones (r = .23), which matters for social media posts. Norms that researchers presented to people in experiments were also more weakly linked to giving (r = .11) than norms people already held (r = .36). The authors say the results should be interpreted with caution. So a post that shows real participants is a reasonable bet, not a guaranteed effect, and inflating a count to strengthen it would add risk without any proven gain.

## What should the nine GivingTuesday posts say?

The nine posts below are written for Maple Street Food Bank, a fictional organization, across three phases. Each post has one job, and every number in brackets must be a true figure pulled at the moment you post. They are practitioner templates, not tested copy. The day's emails, which carry most of the direct asks, are covered in our [GivingTuesday email sequence](https://donorinsights.com/articles/giving-tuesday-email-sequence).

Nine GivingTuesday posts for a fictional organization, by phase (practitioner templates, and every bracketed number must be real)

| Phase | Post | Sample text |
| --- | --- | --- |
| Before (Nov 24 to 30) | 1. The goal | On December 1 we are asking [number] neighbors to give, enough to stock [one concrete result]. Mark the day. |
| Before | 2. A supporter in their own words | "[One sentence from a real volunteer or donor, used with permission]." [Name] will be giving on December 1. Will you join them? |
| Before | 3. The ask to share | Know someone who cares about hunger in [town]? Share this with one friend before Tuesday. |
| During (Dec 1) | 4. Morning launch | It is GivingTuesday. Our goal: [number] gifts by midnight for [result]. [Link] |
| During | 5. Midday count | [Actual number] people have given since this morning. [Remaining number] to go. [Link] |
| During | 6. Evening deadline | [Hours] hours left. We are [number] gifts from the goal. [Link] |
| After (Dec 2 to 4) | 7. The thank-you | [Actual number] of you gave yesterday. Thank you. Here is what that means: [result]. |
| After | 8. The volunteers and sharers | [Actual number] of you also shared, volunteered, or spoke up. That counts too. Thank you. |
| After | 9. The first report | The first [unit] funded on GivingTuesday went out today. [Photo, used with permission.] |

## How do you make each post show real people taking part?

The research points at three choices. First, name people near the reader. The link between norms and giving was strongest when norms referred to friends and family. This is our application of the finding, not something the study tested: posts 2 and 3 use a real supporter's words and ask followers to share with one friend, which puts the norm in a friend's voice. Our guide to [social proof in ask amounts](https://donorinsights.com/articles/social-proof-ask-amounts) applies the same idea to the gift amount in an appeal. Second, say where the money goes. In Bloomerang's 2026 Giving Signals survey of more than 1,000 active U.S. donors, conducted with The Harris Poll, 94% said they are motivated to give when an organization tells them exactly where their money will go, according to [Bloomerang's release](https://bloomerang.com/news/bloomerang-releases-2026-giving-signals-report). That is a stated motive rather than observed behavior, but it is why every post names one concrete result. Third, keep every count true. A midday post that says 212 people gave when 140 did is a false statement to your own supporters, and the evidence gives no reason to take that risk.

Social posts support the day's emails rather than replace them. The same Bloomerang survey found that 69% of donors prefer email, and email was the top preferred fundraising channel in every generation, and the report describes social media as a complement that matters more for some generations than others. Use social to show participation and invite sharing, and let email carry the direct ask. Most organizations already have an audience to post to: in [M+R Benchmarks 2026](https://mrbenchmarks.com/social-media-influencers/), Facebook and Instagram were the most widely used social media platforms, with nearly all participating nonprofits active on them, and the average participant had 53,000 Facebook followers, against 18,000 on Instagram.

## What should you post after GivingTuesday?

The three after-day posts are there to turn a one-day crowd into supporters who stay. Use these steps:

1. Post the thank-you by the next morning, with the true count of people who gave, before any other message.
2. Thank the people who shared, volunteered, or spoke up in a separate post. In 2025 those groups grew faster than giving did, and they are people who already chose to take part.
3. Post the first report on what the day paid for within a week, with a photo used with permission, and invite new donors to give monthly. In GivingTuesday Data Commons research on 2021 to 2025 transaction data, donors on monthly schedules had a median annual value of $275, against $100 for donors not on a recurring schedule.
4. Save the day's comments and shares, so next year's before-the-day posts can quote real supporters.
5. Follow the day's new donors into the new year. What a GivingTuesday donor is worth depends on whether they give again, which our guide to [GivingTuesday economics](https://donorinsights.com/articles/giving-tuesday-economics) works through.

That last step is where the posts are judged. Donor Insights reads your own contacts and gifts, so the people who first gave on December 1 become a group you can follow, to see how many give again in 2027. The [methodology](https://donorinsights.com/methodology) starts from your own giving records, and the [platform](https://donorinsights.com/platform) keeps the GivingTuesday group in view long after the posts have scrolled away.

## FAQ

**How many social media posts should we plan for GivingTuesday?**

A workable plan is nine: three in the week before December 1, three on the day (morning, midday, evening), and three in the days after. That is practitioner guidance, not a tested number. Adjust the count to the channels your supporters actually use.

**What is social proof in a GivingTuesday post?**

It is showing readers that other people, ideally people like them, are taking part. A 2025 meta-analysis of 100,469 people found social norms linked to giving at r = .18, and most strongly when the norm referred to friends and family.

**Is it all right to round up a donor count in a post?**

No. Post only the true number at the moment you post. The research on social proof is mixed, with no significant effect in preregistered studies (studies whose analysis plan was filed in advance), so an inflated count adds risk to your credibility without any proven gain.

**Should social posts or emails carry the GivingTuesday ask?**

Email should carry the direct ask. In Bloomerang's 2026 survey of more than 1,000 active donors, 69% said they prefer email, and email was the top preferred fundraising channel in every generation. Social posts work best for showing participation and inviting supporters to share with friends.

**How many people take part in GivingTuesday?**

About 38.1 million people in the U.S. took part in GivingTuesday 2025, according to GivingTuesday's own estimate. About 19.1 million gave money, 20.9 million spoke out for causes, 13.5 million gave goods, and 11.1 million volunteered, and one person can be counted in several groups.
