Why trust is becoming an increasingly important KPI for PR and marketers

For years, PRs and marketers have lived and died by performance metrics.

Website traffic. Click-through rates. Social engagement. Cost per lead. Share of voice.

While these metrics remain important, they only tell part of the story. As the way people search, research and buy continues to evolve, one factor is quietly becoming more influential than all the others.

Trust.

It’s not as easy to measure as website visits or email open rates, but it’s becoming one of the biggest drivers of business growth. In a world where AI can generate endless content in seconds and customers have more choice than ever before, trust is what separates the brands people notice, from the brands they choose.

For marketers, that’s changing the role of marketing itself. It’s no longer just about generating awareness or driving clicks. Increasingly, it’s about building credibility, demonstrating expertise and giving customers confidence that your business is the right one to work with, specify or purchase from.

Whether you’re selling aluminium windows, heat pumps, software or professional services, buying journeys have become significantly longer and more complex.

Customers rarely discover a business and make a purchase decision straight away. Instead, they gather information from multiple sources before they’re ready to speak to your sales team.

They’ll visit your website, browse your LinkedIn page, read reviews, compare competitors, look at completed projects or case studies, search for your business on Google, ask ChatGPT for recommendations and see whether your company appears in respected trade publications.

By the time someone fills in your enquiry form, they’ve already formed an opinion about your business.

The question is: what impression have you given them?

Every article they’ve read, every customer story they’ve seen and every expert opinion they’ve come across contributes to that decision. Marketing is no longer about a single touchpoint – it’s about building confidence at every stage of the journey.

Creating content has never been easier.

AI tools can produce blogs, emails, social posts and marketing copy in minutes. Every day, thousands of businesses publish articles covering the same topics, often with very similar advice.

For prospective clients and buyers, that’s created a new challenge. How do you know who to believe?

When everyone can publish content, expertise becomes the differentiator. Buyers are increasingly looking for brands that can demonstrate genuine knowledge rather than simply making claims.

That’s why thought leadership, original research, customer case studies and expert commentary have become so valuable. They offer something AI can’t invent – real experience, informed opinion and practical insight.

The brands that stand out aren’t necessarily publishing more content. They’re publishing better content that reflects genuine expertise.

It’s easy for any business to describe itself as an industry leader.

Every company promises exceptional service. Every manufacturer claims to produce market-leading products.

However, customers have become increasingly sceptical of self-promotion.

What builds trust is evidence, whether it’s independent media coverage, detailed customer case study, speaking at a recognised event or original research that contributes new insights to the sector.

Collectively, these signals tell a much more convincing story than marketing messages alone ever could. It’s the difference between saying you’re an expert and allowing others to recognise you as one.

AI is making trust even more valuable

The rise of AI search has only accelerated this trend.

Whether someone is using ChatGPT, Google AI Mode or Gemini, AI platforms are increasingly looking beyond a company’s own website when generating responses.

They assess information from across the web, drawing on trusted publications, expert commentary, customer discussions and authoritative sources to determine which brands deserve to be recommended.

That means businesses can no longer rely solely on optimising their own website. They need to build authority across the wider digital landscape.

The businesses consistently earning media coverage, publishing original insights and contributing expert opinions are creating the kinds of signals that both people and AI systems recognise as trustworthy.

In many ways, trust has become a visibility strategy.

So, what should you be measuring?

Traditional KPIs will always matter, but it’s becoming increasingly important to explore further metrics that indicate levels of trust and authority.

For example, asking:

• Are more people searching for our brand by name?
• Are we earning coverage in publications our customers actually read?
• Are prospects already familiar with our business before they enquire?
• Are customers recommending us to others?

These aren’t vanity metrics. They’re indicators that your reputation is growing and that trust is becoming a competitive advantage.

The future belongs to credible brands

Marketing will continue to evolve. New platforms will emerge, algorithms will change and AI will reshape how people discover information.

But one thing is unlikely to change. People will always choose businesses they trust.

For marketers, that’s both a challenge and an opportunity. The brands that invest in expertise, thought leadership, customer stories and meaningful PR today are building something much more valuable than awareness alone.

They’re building credibility.

And in a world where attention is increasingly difficult to earn, credibility may well become marketing’s most valuable KPI.
