What makes nonprofit advertising successful? For our 2026 Nonprofit Ad Benchmarks Report, we tested 33 donation ads from 14 nonprofits, measuring how each one moved five outcomes: donation intent, trust, favorability, perceived impact, and recommendation intent. We also asked viewers to rate each ad on 13 creative attributes, from effective to humorous to urgent, and checked which of those attributes actually correlated with the outcomes that matter.
One pattern held up more than any other: the attributes that build donor trust are the same ones that drive giving intent.
The nonprofit advertising attributes that drive both trust and donations
The attributes that establish an organization's character and credibility are not just the strongest predictors of brand perception. They are also the strongest predictors of giving. Effectiveness, perceived impact, and shared values sit at the top of both columns: an ad that convinces someone the organization gets results, that a gift will matter, and that it stands for what they stand for, is doing the most efficient work on the relationship and the ask at the same time.
To put it simply: viewers who rated a nonprofit fundraising ad as effective mostly rated it as trustworthy too, and were more likely to say they'd give. That's not two separate wins stacked on top of each other. In this data, it's the same creative work showing up twice.
Humor didn't share that pattern. Across the 33 ads, how funny or playful an ad felt had close to no relationship with donation intent and barely any with trust. That doesn't mean nonprofit digital advertising should never be lighthearted. It means a joke has to earn its place alongside the attributes that are actually doing the work, not instead of them.
What this means for your next nonprofit ad campaign
The practical read for anyone planning nonprofit advertising campaigns: you don't have to choose between an ad that builds your brand and an ad that focuses on the actual donation ask. The ads in this study that came across as trustworthy, effective, and aligned with the viewer's values were pulling both levers at once. If your team has been treating brand awareness and direct response as separate creative tracks with separate success metrics, this data says the best-performing work is doing both jobs with the same attributes.
Here's a quick gut check you can run on your own concept before you spend on testing or media: would a stranger who has never heard of your org call this ad trustworthy, on its own, with the sound off? And does it make a specific, believable claim about what a donation does? If you can't answer yes to both, that's worth fixing before you worry about the ask itself. In this data set, ads that read as trustworthy and effective were the stronger bet for both the brand and the ask.
