Straight answer: AI writing tools default to the same safe, polished middle ground unless you feed them specific facts about your business, which is why thousands of small business websites now read like they were written by the same person. In a sense, they were. The fix isn't dropping AI, it's giving it your real details, your real numbers and your real customers' words before you let it write a single sentence.
The test that made me stop trusting AI copy on its own
A few months ago a client sent me her new homepage, freshly written with ChatGPT, and asked what I thought. Before I said anything I ran my own test. I gave three different AI tools, ChatGPT, Claude and Gemini, the exact same three-line brief: write a homepage headline and opening paragraph for a bookkeeping firm that works with small trades businesses.
All three came back within seconds. All three used the phrase "so you can focus on what you do best." Two of the three used the word "streamline." All three opened with some version of "running a small business is hard enough." None of them mentioned a single fact about the actual firm, because I hadn't given them any, but that's exactly the point. Left to guess, every model reaches for the same middle-of-the-road phrasing, because that's what most of the internet already sounds like.
I then went back through twenty real homepages that clients had sent me over the past few months, asking for feedback before launch. Eleven of the twenty opened with some near-identical version of "in today's competitive market, finding a partner who understands your needs has never been more important." Eleven out of twenty, from businesses that had nothing to do with each other, in different towns, different industries, all sounding like the same brochure.
Why this happens, and why it isn't really the AI's fault
Large language models are built to predict the most statistically likely next words based on everything they've read. When you give them a vague brief, they don't invent something distinctive, they average toward the safest, most common phrasing in their training data. That's not a flaw, that's the job they were built to do.
Here's the bit most people writing about AI marketing skip over. Everyone tells you AI can write your whole website in an afternoon, and that's true. What they don't say is that if you do it with no specific input, you're not saving time, you're outsourcing your identity to the average of everyone else's website. Customers might not consciously notice the sameness, but they feel it. Sameness reads as forgettable, and forgettable is expensive when you're a small business competing against firms with ten times your marketing budget.
The businesses that never had this problem
Distinctiveness isn't a new marketing idea, AI just made it easier to lose without noticing. Disney built an entire empire on a story-first voice that never sounds like a generic entertainment company, and if you look at how deliberately that voice was built and protected over decades, in this Disney marketing strategy breakdown, you can see it was never left to chance or to a default template.
Headspace is a good example closer to a small business scale. It sits in a crowded market where dozens of competitors could have used the same soft, calming, slightly clinical tone, and instead it chose playful, plain language and a bit of humour, which I've written about in the Headspace marketing strategy piece. That choice to sound different, on purpose, is the whole game.
Coco Chanel is the sharpest example of this, long before anyone had a laptop. She built a brand by deliberately doing the opposite of what fashion was doing at the time, stripping things back when everyone else was adding more. There's a lesson buried in the business lessons from Coco Chanel that applies directly here: the businesses winning attention in 2026 will be the ones doing the opposite of what everyone else's AI is currently producing.
The 5-step brand voice audit I run before any AI copy gets written
This takes most business owners two to three hours if they're honest with themselves. I don't skip it with clients, no matter how quick they want the website turned around.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
- Pull three real messages. Find three actual emails, reviews or texts from customers describing why they came to you or what they said afterward. Lift the exact phrases they used, not your polished version of what you think they meant.
- List five facts no competitor can claim. Years trading, number of clients served last year, a specific process step, a guarantee, a location detail. Numbers beat adjectives every time.
- Write down three words you must never sound like. Usually these are the words your biggest competitor uses. Then write three words you want to own instead.
- Give the AI a banned phrase list. After my test I now hand clients a short list including "streamline," "so you can focus on what you do best," and "in today's competitive market," and tell them to feed it into the prompt as things to avoid.
- Read the output aloud. If a sentence could sit on a competitor's site unchanged, rewrite that line using one of the facts from step two.
Why polished can work against you
There's a behavioural point buried here that most marketing writers avoid because it sounds like they're arguing against their own advice. Richard Thaler's work on choice and defaults, which I go into in these business lessons from Richard Thaler, points to something useful: people are wary of anything that feels too smooth and too default. A homepage that reads like every other homepage triggers the same low-level suspicion as a scam email written a little too perfectly. Small imperfections, specific quirks, and slightly rough edges signal a real human business, not a template. Chasing perfectly polished AI copy can quietly cost you trust, not build it.
Give people something to do, not just something to read
One of the fastest ways to break out of the sameness problem is to stop competing purely on copy and give visitors something interactive instead. A calculator, a quiz, a quick cost estimator, anything that gives a visitor a personalised answer does two things at once: it keeps people on the page longer and it can't be copy-pasted by a competitor's AI tool. I've written before about how interactive calculators help engage and convert more visitors, and it's one of the few tactics that's got more useful since AI copy became this common, precisely because it's harder to make generic.
When it's worth bringing someone else in
If you've tried the audit above and your homepage still reads flat, that's usually not a copywriting problem, it's a not-knowing-what-makes-you-different problem, and no amount of prompting fixes that on your own. This is the bit I get paid to do with clients, sitting across the table asking annoying questions about their business until the real answer shows up. A half-day session with someone who does this well typically runs between £600 and £1,200 depending on the consultant and the size of the business, which is far cheaper than another year of a website nobody remembers. If you want a second pair of eyes on this before you touch another prompt, this is exactly the kind of work an AI consultant for small business should be doing with you, not just handing you a longer prompt template.
What I'd do this week if I were you
Open your homepage right now and read the first paragraph aloud. If it could sit unchanged on your closest competitor's site, that's your answer. Pull one real customer message, lift one real number about your business, and rewrite just that opening paragraph today. Don't touch the rest of the site yet. Small, specific, uncomfortable details beat another smooth AI paragraph every time.
