Writing great advertising copy sounds simple. Say what you sell, explain why it matters, and ask people to act. But most small business owners find it much harder in practice.
The wrong words can make your ad invisible. Worse, they can actively put customers off. Whether you run a boutique gym, a restaurant, or an independent retail shop, your copy is often the first impression you make. It needs to work.
This guide covers the most common mistakes and how to fix them today.
The biggest mistake in advertising copy is talking about yourself too much. "We've been trading since 1998." "Our team is passionate and dedicated." "We pride ourselves on quality."
Your customer does not care about your pride. They care about what you can do for them.
Flip every sentence. Instead of "We offer expert personal training sessions," try "Get fitter in 30 days with a plan built around your goals." One sentence is about you. The other is about the reader.
This is especially true in hospitality and fitness, where emotion drives decisions. Sell the feeling, not the feature.
Many SME owners try to appeal to everyone. The result is copy that resonates with no one.
Picture one specific customer. Give them a name if it helps. What are they worried about? What do they want? What would make them stop scrolling and pay attention?
A gym might target time-poor professionals who feel guilty about skipping workouts. A restaurant might speak to couples looking for a relaxed Friday night out. A boutique retailer might write for someone tired of buying the same thing from the high street.
The more specific you are, the more people will feel you are talking directly to them.
Words like "high quality," "innovative," and "world-class" are everywhere. They say very little and prove even less.
Specificity builds trust. "Over 2,000 members trained since 2019" beats "thousands of satisfied customers." "Sourced daily from New Covent Garden Market" beats "fresh ingredients." "Returns within 48 hours, no questions asked" beats "great customer service."
Concrete details are memorable. Vague claims are forgettable. Choose one over the other every time.
Most people will only read your headline. If it does not hook them, they will move on before reading a single word of your body copy.
A strong headline does one of three things. It promises a benefit, solves a problem, or sparks curiosity. Ideally, it does more than one.
Weak headline: "Summer Menu Now Available"
Stronger headline: "Our New Summer Menu Is Here and It's the Best We've Ever Done"
Even stronger: "Tired of Eating the Same Thing? Our Summer Menu Changes That"
Test your headlines. Show them to a colleague or a loyal customer. If they shrug, rewrite.
You have written brilliant copy. Now what do you want the reader to do?
Many ads forget to answer this question clearly. They inform and entertain but never push the reader to act. Every piece of advertising copy needs a clear, specific call to action.
"Book a free trial session today" is better than "get in touch."
"Reserve your table for Friday night" is better than "find out more."
"Shop the new collection" is better than "visit our website."
Be direct. Tell people exactly what to do and make it easy for them to do it.
Journalists are taught to put the most important information first. Advertisers often do the opposite. They build slowly towards the main point and lose the reader along the way.
Lead with your strongest benefit or most compelling idea. You can always give more detail afterwards.
If you are running a promotion, say so immediately. If you have won an award, mention it early. If you solve a specific pain point, put that right at the top.
Readers skim. Make sure your most important message lands even if they only spend three seconds on your ad.
A luxury spa and a budget gym are both in the fitness industry. Their customers expect very different things from their advertising.
Your tone should reflect who you are and who you are speaking to. A friendly, casual tone works well in retail and hospitality. A motivating, no-nonsense tone suits performance-focused fitness brands. A warm, reassuring tone fits family restaurants.
Read your copy aloud. Does it sound like a real person talking to a customer? Or does it sound like a corporate press release? If it is the latter, simplify it.
Typos and grammatical errors undermine your credibility immediately. They suggest carelessness, and carelessness in your copy makes customers wonder about carelessness in your service.
Do not rely on spell-check alone. Read your copy slowly. Read it backwards. Ask someone else to check it.
This applies to social ads, Google ads, flyers, and email campaigns alike. There are no shortcuts here.
No one writes perfect copy first time. The best copywriters test multiple versions and let the results guide them.
If you are running paid ads, try two versions with different headlines. See which one gets more clicks. Refine the winner and test again.
Even for printed materials, you can ask customers which message resonates more. Small experiments compound over time. Your copy will get sharper the more you pay attention to what actually works.
Great advertising copy is not about clever wordplay or flashy language. It is about understanding your customer, speaking to them directly, and giving them a reason to act.
Start by fixing the basics. Write for one person. Lead with benefits. Be specific. Add a clear call to action. Then refine from there.
