In 2026, 58% of searches are zero-click, meaning the user gets the answer from an AI summary without ever visiting your site.
If the AI describes your brand as "a generic digital agency" because your content is mid, you’ve lost the Capture and Connection phases before the journey even begins.
The best way - and by that we mean cheap and easy - is by optimising not just what your content says, but how it says it.
Tone of voice is essential for making your business likeable. It creates a persona that makes your customers and prospects feel safe.
I mean who isn't a fan of Ryanair and Wendy's for their sassy clapbacks on social media?
And yes, there's a behavioural science reason why this works:
The trust gap:
77% of consumers believe pure AI-generated marketing reduces brand authenticity. However, 24% of users are more likely to trust a brand if they know a human is guiding the AI (Clutch 2026).
This is becoming a problem as regulatory bodies like the FCA are cracking down on AI generated content because of this. And the kids are now saying "that's AI" to each other, meaning it's fake, like we used say "chinny reckon" because of Jimmy Hill (no, I don't get how the two are related either, so "that's AI" makes much more sense, thinking about it).
The discovery shift:
Over 60% of product discovery now happens via social search (TikTok/Instagram) and AI assistants, while traditional Google search share has dipped to 34.5% (Sprout Social 2026).
And on socials, personality wins the algorithm over formulaic content as this is what makes people stop, look and listen. Getting the same personality on every 60 second video is what we all look for, it's a memory marker that tells us we're in a familiar place.
Interaction efficiency:
Brands using proprietary brand voice models (training AI on their specific "Bricks") see a 37% increase in conversion from AI-answered queries compared to those using generic outputs.
For many businesses, however, injecting personality into copy is a luxury they can't afford or don't have the skill to execute. And for big companies with a content team (however small), you don't want to waste that valuable expertise fiddling with micro-copy, those annoying JFDIs you won't get seen or when you need something quick and dirty.
You can now train your LLM to speak your brand language.
This also has the added bonus of acting like a peer review by someone who'll never get tired, isn't in endless meetings and is at risk of having the gaul to be off sick.
That said, it's important it gets reviewed by a content expert who is human, as AI won't be able to check for context, accuracy or relevance. This is where you need critical thinking and behavioural science to reign supree
