Only 10% of UK adults trust social media ads, YouGov finds

Ten percent of British adults trust the advertising they see on social media, according to a YouGov survey highlighted by Campaign UK. The single-digit trust reading lands as UK ad spend on Meta, TikTok and YouTube continues to anchor digital plans for the year ahead.

The figure, framed by Campaign UK as "1 in 10 Brits," gives brand teams a hard data point for a conversation that has historically been argued in anecdote. It also arrives without the underlying cross-tabs in the public reporting, leaving sample size, fieldwork window, and the share of respondents who actively distrust the ads unclear.

What does the number actually show?

The headline 10% functions as a ceiling, not a floor. Without the active-distrust figure, practitioners can't quantify the full skepticism gap or compare it to prior YouGov waves. They also can't segment the response by age, region, or platform, each of which would shape a different budget decision.

For agencies, the immediate use of the figure is reputational rather than targeting. It gives planners a citation when clients ask why paid social underperforms brand-lift studies despite strong click-through and view-through numbers. A 90% non-trust baseline affects upper-funnel and brand-defense work most heavily, where credibility is the asset being bought.

What does it cost marketers in practice?

UK marketers allocating spend across paid social, search, and creator partnerships now have to weigh three operational signals:

• A 90% non-trust floor that caps the upper limit of any awareness campaign.
• An absence of comparative trust data for other channels in the same survey wave, which limits the case for wholesale reallocation away from social.
• A likely spillover into adjacent debates — influencer disclosure, AI-generated creative, political-ad transparency — where trust deficits compound rather than cancel out.

For small and mid-size brands running on tight margins, the practical response is rarely "cut social." It is reweighting spend toward formats with stronger trust signals — disclosed creator sponsorships, search, and editorial — while treating paid social as a performance layer rather than a credibility layer.

What should brands and platforms watch next?

The next move belongs to YouGov. Publishing the full methodology, demographic splits, and a year-over-year comparison would convert a striking headline into a benchmark agencies can use in next quarter's planning. Until those tables land, brands can treat 10% as a directional warning rather than a reallocation trigger.

Platforms face a more direct test. Trust in the ad layer is a precursor to the brand-safety, suitability, and disclosure reforms UK regulators and major advertisers have demanded over recent quarters. A reading of 1 in 10 sharpens the commercial case for incremental product changes: clearer paid labels, stricter creator-disclosure enforcement, and a reduction in low-quality ad inventory. Each of those changes now carries measurable upside, not just compliance value.

The campaign calendar won't pause for clarification. Agencies briefed on the finding should expect the next planning review to include a direct question: if 90% of UK adults don't trust the ads being paid to reach them, what does the creative, channel mix, and measurement stack need to change to convert the 10% who do?
