Trust in Ads Is Rising—Make Your Marketing Credible

40% of the UK public said they trusted advertising in 2025—the highest level recorded in five years, according to the Credos Trust Tracker (surveying ~2,000 people annually). That’s not a feel-good stat for big brands only. For UK small businesses, it’s a practical signal: people are more open to being persuaded than they were a few years ago—if your marketing looks honest and behaves responsibly.

Here’s the catch. The same research describes consumers’ relationship with advertising as “complex” and sometimes “contradictory”. In plain English: people can enjoy ads and still assume they’re being manipulated. They can trust a channel (like TV) and distrust the behaviour they see online (like scams, undisclosed sponsorships, or greenwashing).

This post sits in our Governance, Regulation & Public Trust series because trust isn’t just a brand concept—it’s governance in action. It’s the day-to-day proof that your business tells the truth, respects customers, and plays by the rules. If you want more leads in 2026, trust is the shortest path.

What the trust data really tells small businesses

Answer first: Trust is improving, but it’s fragile—one “suspicious” ad can undo months of good work, especially for a local brand with a small reputation footprint.

Credos found:

• 40% of the UK public trusted advertising in 2025 (vs 39% in 2024).
• Only 11% were very trusting; 29% were fairly trusting.
• 25% actively distrusted ads; 33% were neutral.

So yes, the headline number is up—but don’t read it as “people trust ads now”. Read it as: a meaningful slice of your market is persuadable when you show them something clear, useful, and credible.

The most underrated insight: trust drivers are split 50/50

Credos reports that in 2025, the importance of positives vs negatives in driving trust was exactly 50/50.

That’s a big deal for small businesses because it means:

• You don’t win trust only by making great content.
• You also win trust by removing anything that looks dodgy.

A major driver of distrust is what the research calls “suspicious advertising”—scams, misleading claims, undisclosed ads, greenwashing, and manipulated imagery.

If you want leads, you need two tracks running at the same time:

1. Add value (helpful ads, proof, clarity)
2. Reduce suspicion (transparency, compliance, clean user experience)

Why “traditional” channels are gaining trust (and what to copy digitally)

Answer first: People trust channels that feel regulated, familiar, and less scam-prone—so your digital marketing should borrow those cues.

Credos found trust increased across every channel versus 2021, with some of the biggest gains in “traditional” media:

• TV: 46% trust in 2025 vs 33% in 2021
• Cinema: 42% trust vs 33%
• Radio also ranks highly in trust

Meanwhile:

• Influencer advertising is least trusted, though improving (25% in 2025 vs 19% in 2021)
• Social media ads improved too (27% in 2025 vs 20% in 2021)

What’s happening here

TV and cinema aren’t “more honest” by magic. They feel safer because:

• The ad environment is more controlled
• Fraud feels less common
• Production quality signals investment and accountability

Small businesses rarely have TV budgets, but you can still borrow the trust-building mechanics:

• Consistency: same promises everywhere (site, ads, socials)
• Clarity: no tiny-print gotchas
• Professional presentation: not glossy for the sake of it—just competent and coherent

Practical takeaway: make your digital ads feel “regulated”

You can’t control the whole internet, but you can control your corner of it. Simple trust cues matter more than most businesses admit.

A “regulated feel” online looks like:

• Real business details (address, phone, VAT number if relevant)
• Clear pricing or “from” pricing with conditions stated
• Straightforward cancellation/returns if you sell online
• No manipulative timers or fake scarcity (“Only 1 left!!!”) unless it’s true

That’s not aesthetics. That’s governance, translated into marketing.

The 5 credibility plays that generate leads in 2026

Answer first: Credible marketing converts because it reduces perceived risk—so focus on proof, transparency, and a frictionless customer experience.

Below are five tactics I’ve found consistently work for UK SMEs across trades, local services, and ecommerce.

1) Replace hype with verifiable claims

If your ad says “Best in London”, people roll their eyes. If it says “4.8★ average from 312 reviews” (and they can verify it), they lean in.

Try this structure:

• Claim: what you do
• Proof: evidence
• Terms: the boundary conditions

Example:

• “Boiler service from £89”
• “Includes full safety check + service report”
• “Price applies to standard combi boilers within Zones 1–4”

This is a trust-first approach that also protects you from complaints.

2) Make your ads enjoyable—but don’t confuse “fun” with “vague”

Credos found enjoyment was the factor most likely to drive trust. That’s counterintuitive, but it tracks: people trust what feels human.

Enjoyable doesn’t mean gimmicky. For small businesses, it often means:

• Clear, plain-English writing
• A recognisable founder/face (even just a short video)
• Specifics that show competence (“We’ll text when we’re 20 minutes away”)

If you can make someone think, “These people seem normal and capable,” you’re ahead.

3) Label paid partnerships and gifted products properly

Influencer trust is still low for a reason: people feel tricked when sponsorship is hidden.

If you use creators, bake transparency into the brief:

• Use clear disclosure (e.g., “ad”, “paid partnership”, “gifted”)
• Ask for honest pros/cons, not a script
• Avoid filters or image manipulation that misrepresents results

It sounds risky to allow nuance, but it usually increases conversions because it feels real.

4) Use “proof stacks” on landing pages (not just testimonials)

Testimonials help, but they’re easy to fake. A proof stack mixes different evidence types so the page feels hard to counterfeit.

A strong proof stack for SMEs includes:

• Review platform widgets or screenshots with dates
• Before/after images with context
• Accreditations (Gas Safe, NICEIC, FCA permissions, ICO registration—whatever applies)
• Short case studies (problem → approach → result)
• FAQs that answer awkward questions upfront

If your goal is leads, your landing page should reduce anxiety faster than your competitor’s.

5) Treat your ad funnel like a compliance system

This is the Governance, Regulation & Public Trust point that most marketers ignore: trust is operational. It lives in your processes.

Build a simple internal checklist for every campaign:

• Are we making any claims that need evidence?
• Are images accurate and representative?
• Are terms (pricing, eligibility, deadlines) clearly visible?
• Are we collecting data lawfully and explaining why?
• Is there a real person customers can reach?

You don’t need a legal team. You need discipline.

Channel-by-channel: where to put your next pound if you want trust

Answer first: Put budget into channels where you can show proof and control context—then use social to amplify, not to explain.

Given Credos’ findings (higher trust in traditional channels, lower in influencer/social), here’s a sensible SME approach.

SEO: the “quiet trust builder”

SEO doesn’t feel like advertising to many customers, which is exactly why it works. High-intent searches are often trust-seeking behaviours (“best”, “near me”, “reviews”, “cost”).

What to prioritise in Q1–Q2 2026:

• Service pages with pricing ranges and clear inclusions
• Local pages (town/borough) that show real projects and photos
• Google Business Profile updates (posts, FAQs, new images)

Paid search: trust through intent and clarity

Paid search works when your ad matches what people already want.

To keep it credible:

• Avoid bait-and-switch offers
• Send each ad group to a tightly relevant landing page
• Use extensions (call, location, structured snippets) to reduce uncertainty

Social ads: keep them simple and proof-led

Social can generate leads, but trust is fragile there because the environment is noisy.

What performs well without looking “suspicious”:

• Short videos showing the process (not just the result)
• Customer stories with specific outcomes
• Clear offers with clear terms

Influencers/creators: use them for demonstration, not persuasion

If you use creators, pick ones who can show the product/service in use.

Rule of thumb: the more the creator has to “say”, the less people believe it. Demonstration beats persuasion.

People also ask: “If trust is rising, why do my ads still underperform?”

Answer first: Your ads aren’t competing against other small businesses—they’re competing against scams, spam, and bad experiences.

Even with rising trust, consumers are trained to look for red flags. Underperformance usually comes from one of these:

• Unclear offer or hidden conditions
• Weak proof (generic testimonials, no verifiable reviews)
• Over-edited visuals that feel misleading
• Poor landing page experience (slow, confusing, mobile-unfriendly)
• Inconsistent messaging between ad and website

Fixing those often increases conversion rates without increasing spend.

What to do next: a 30-day trust-first marketing plan

Answer first: In one month, you can remove suspicion and add proof—two changes that reliably improve lead conversion.

Here’s a tight plan:

1. Week 1: Audit for “suspicious” signals

   • Rewrite ads to remove exaggerated claims
   • Add clear terms to offers
   • Check imagery is representative

2. Week 2: Build a proof stack

   • Add 3–5 case studies (even short ones)
   • Add accreditation badges with explanations
   • Add review evidence with dates and volume

3. Week 3: Improve landing page clarity

   • One page = one job
   • Put price range, availability, and service area above the fold
   • Add a phone number and response-time promise

4. Week 4: Run a small test and measure trust proxies

   • Track lead-to-sale rate, not just clicks
   • Monitor refund/complaint signals
   • Ask new leads: “What made you choose us?”

Trust is measurable in behaviour: fewer objections, fewer no-shows, better close rates.

Credible advertising isn’t “nice to have” in 2026. It’s how you avoid being filtered out before you ever get a chance to sell.

Where does this leave us in the broader Governance, Regulation & Public Trust story? Public trust rises when institutions—and businesses—show they can self-regulate: tell the truth, label what’s paid, and respect the customer’s right to understand what they’re buying. The brands that grow this year will be the ones that make transparency feel normal.

If you want more leads, start with one question: what would a cautious customer need to see to feel safe choosing you?
