Words That Sell (and Ones That Don’t) – How to Write Effective Ad Copy

by | Oct 14, 2024 | marketing

“Unlock Your Best Life — Guaranteed.”

The words practically jump off the screen.

You stop. 

You weren’t even looking for anything, but here you are, clicking. 

We’ve all been there, right? 

Scrolling past endless “Buy Now!” or “Don’t Miss Out!” ads like they don’t even exist, but then — bam — one stops you in your tracks.

So, why did you stop?

It’s all in the words.

The right words stir curiosity, pull you in, and make you want to learn more. 

The wrong ones? They’re like white noise in the background, easy to ignore.

The good news is that you can learn how to write effective ad copy and it doesn’t require you to be a wordsmith! You just need to know your audience and speak their language. 

Ready to dive in? Let’s unlock the secrets to writing irresistible copy.

How to Write Effective Ad Copy – Why Words Matter

People have shorter attention spans than ever. When looking at print ads, we only spend 2-4 seconds before moving on. That’s why ads must grab attention, build interest, and get people to act. 

Think of your ad as a first impression at a party. You’ve got seconds to make people want to know more or politely step away. The words you choose in your copy aren’t just fillers, they serve as your handshake, introduction, and first smile.

I know, I know, that’s a lot of pressure! 

But that’s why using the right words is so important.

Here are a few reasons why they matter:

First Impressions Are Everything

Your words are often the first (and maybe only) impression your audience gets of your brand. A strong, clear message sets the tone. In those precious seconds, your words need to do all the heavy lifting so they must count.

Emotions Drive Decisions

People make decisions based on feelings before justifying them with logic. The right words can stimulate excitement, trust, or even a little FOMO (fear of missing out). But the wrong words? They can make people doubt or simply feel “meh.” 

Words don’t just inform; they evoke emotions. And those emotions decide whether someone will engage with your ad. A well-placed “exclusive” or “limited-time” can trigger excitement, while weak words like “maybe” or “probably” can make people feel unsure.

It’s About Brand Connection 

Ads don’t just sell products, they build relationships. Words that feel relatable and human will always outperform cold, corporate language. The language you use doesn’t just sell your product, it shapes how people see your brand. 

Use personal language, and your brand comes across as friendly and approachable. But use corporate jargon, and suddenly, you’re the intimidating company no one wants to deal with.

Words That Sell – Word To Use For Effective Ad Copy

There’s magic in certain words. 

They carry energy, action, and intent. Words that work activate action, spark emotion and get people to engage. 

Let’s break down certain word choices that can inject some edge into your copy.

Action Verbs That Inspire

Ever noticed how certain ads dare you to take action? That’s no accident. Words like “Discover,” “Unlock,” or “Transform” turn passive readers into engaged customers by promising something exciting.

Tip: Swap out weak calls to action like “Learn More” with verbs that stir up action. 

For example:

  • Instead of “Find out about our service,” try “Unlock the potential of your business.”
  • Instead of “Click Here,” say “Get Started Today.”

Words That Evoke Emotion

Humans are emotional creatures. Use the right words and you can stir feelings of trust, excitement, or urgency. 

The right words and phrases speak to more than just a product; they tap into a feeling, a mindset.

Tip: Want to stir excitement? Use words like “exclusive,” “proven,” or “guaranteed.” Create your message so your audience feels like they’re getting something special that others don’t have access to.

  • Apple’s “Think Different” makes you feel rebellious and innovative.

Powerful Adjectives That Persuade

Adjectives are as important as action words. 

Imagine the difference between saying “Try Our Service” versus “Experience Effortless Solutions.” Which one feels more compelling?

Tip: Use adjectives that speak to what your audience cares about. If you’re marketing luxury products, use words like “elegant” or “sophisticated.” Selling tech solutions? Opt for “innovative” or “seamless.”

Words That Fall Flat – Avoid These Words in Your Ad Copy

Not all words are created equal. Some kill conversions faster than you can say, “Oh no!” Here’s a breakdown of what words you should stay clear of: 

Words That Create Hesitation or Doubt 

Nothing kills an ad faster than words like “maybe,” “attempt,” or “hopefully.” 

Read those out loud and they scream indecision. If you’re not confident in what you’re selling, why should your audience be?

Tip: Instead of “This product might help you save money,” say “This product will help you cut costs.” Be assertive. Confidence sells.

Negative Words That Turn People Off

Words like “cheap,” “lazy,” or “fail” carry negative baggage. Even if you’re trying to warn customers about a problem, negative language can make them tune out. 

Tip: Always frame your message in a positive light. Instead of “Don’t miss out,” try “Grab this opportunity!” Keep the tone uplifting, and focus on what your audience stands to gain.

Clichés and Overused Phrases

The problem with phrases like “best of the best” or “once-in-a-lifetime deal” is they are so overused that they don’t mean anything anymore. 

Everyone treats them like marketing fluff, tuning out before they finish reading the copy. You want to avoid this at all costs! 

Tip: Get creative. Instead of “best of the best,” plainly describe what sets you apart. Is it your customer service? The speed of your service? The more specific you are, the better.

The Do’s of Crafting High-Conversion Ad Copy

Now that you know the right words to use, we can focus on the essentials of how to write effective ad copy that turns browsers into customers. 

1. Be Clear and Concise

Look at the best ads, they never waste words. They get to the point, fast. Remember, this isn’t a novel, you’re creating a spark of interest.

Tip: Look at brands like Slack, whose ads are always concise and clear. “Make work better” is a perfect example. Three words, but it tells you exactly what the product will do.

2. Use Benefit-Focused Language

I’m gonna say a harsh truth, no one cares about features. People care about benefits. It’s not about what your product does but what it can do for them.

Tip: Instead of saying your product has a “10-hour battery life,” say that it “keeps going all day without recharging.” You’re painting a picture of how the product improves their life, not just rattling off a spec sheet. Check out how Hello Fresh uses benefits on their landing page to convince customers they are worth using.

3. Create Urgency and Scarcity

FOMO is real, and the best ad copy taps into that. Phrases like “limited-time offer” or “only 3 left” are simple but effective ways to get people to act quickly.

Tip: Even online giants like Amazon use scarcity. “Only 1 left in stock” is a common CTA. Don’t overdo it, but sprinkling in scarcity can nudge customers to take action sooner.

4. Write For Your Audience, Not Yourself

Take this to heart. It’s a golden rule of writing effective ad copy.

Your customers don’t want to hear about how great your company is, they want to know what’s in it for them.

Tip: Take a page out of Grammarly’s playbook. Their ads speak directly to the customer’s pain points: “Mistake-free writing.” It’s simple, relatable, and relevant to their audience.

Common Ad Copywriting Pitfalls (and How to Avoid Them)

Even seasoned marketers fall into these traps, but with a little mindfulness, you can steer clear of these common mistakes.

1. Don’t Use Jargon or Complex Language

Nothing kills interest faster than a wall of industry-specific jargon. 

Throwing buzzwords or industry jargon confuses your audience. Keep your language simple. 

Tip: Instead of “Utilize our state-of-the-art technology,” say “Use our cutting-edge tools.” You want to connect, not confuse.

2. Don’t Oversell or Exaggerate

We’ve all seen ads that promise the moon, only to underdeliver. Overpromising can damage your credibility. Keep your ad copy enthusiastic but grounded. 

Tip: Instead of “This will change your life forever,” try “This could be the game-changer you’ve been waiting for.”

3. Don’t be vague

Avoid fluffy, generic language. Phrases like “great quality” or “excellent service” don’t mean much. Your audience needs specifics to get excited.

Tip: Instead of saying “great quality,” say “Our product lasts 5x longer than the competition.” Be specific.

How to Test and Refine Your Ad Copy for Maximum Impact

You won’t know if your copy is succeeding if you don’t test it. And trust me, even the best copy can be improved. To do this right, A/B testing is your best friend.

Which parts should you test? 

I say, test everything! Headlines, CTAs, and even word choice. 

For example, you can test “Start your free trial” against “Get your first month free.” Small changes can lead to big differences in results.

Tip: Use tools like Facebook Ads Manager to test and tweak your ads for optimal performance.

Measuring Success with Metrics

Keep an eye on your KPIs, like click-through rates and conversions. If one version of your copy isn’t performing, don’t be afraid to pivot. Change it up, use an alternate copy or creative asset. There’s always room to improve. 

Wrapping Up

In ad marketing, words are your best tool. 

Words get people to stop, pay attention, and (hopefully) take action. 

The key to learning how to write effective ad copy that converts is to focus on action, emotion, and clarity. Keep it simple, be specific, and make sure your message resonates with your audience.

And remember: The best ad copy isn’t just about selling a product. It’s about starting a conversation — one that leads to connection, trust, and, ultimately, action.
