Good Ad Copy Still Wins—Here's Why

You've Got It Backwards

Most people in advertising think the algorithm does the heavy lifting. They assume that if you throw enough budget at Google Ads and set a decent bidding strategy, the ads basically write themselves. That's wrong. Dead wrong. The truth is, your creative—specifically the words in your ads—determines whether you win or lose. The Google Ads auction is a real-time bidding process that considers bid, quality, and context, but it's not a simple highest-bid-wins game (Google Ads Help (ad rank)). And in that equation, your ad copy is the single most controllable factor that can tip the scales.

The Algorithm Likes Good Copy—But It Can't Write It

Here's how Google Ads actually works. Ad Rank depends on your bid, the quality of your ads and landing page, ad rank thresholds, and the expected impact of ad formats (Google Ads Help (ad rank)). That 'expected impact'? That's where your copywriting shines. Responsive search ads let you write up to 15 headlines and 4 descriptions, and Google automatically tests combinations to find what works (Google Ads Help (responsive search ads)). If you're writing generic, bland headlines, you're leaving performance on the table. The algorithm is designed to reward better copy with lower costs and better placements. And it's not just about clicks—it's about conversions. CTR, which indicates relevance and quality, is clicks divided by impressions times 100 (Google Ads Help (ad metrics)). A higher CTR signals to Google that your ad is relevant, which can lower your actual CPC because your Ad Rank is based on the competitor below you (Google Ads Help (ad rank)).

But here's the kicker: most advertisers are terrible at copywriting. They write ads that sound like everyone else's, and then they wonder why their costs are high. The data backs this up. In 2024, search advertising pulled in $102.9 billion in the US, the largest digital category (IAB/PwC Internet Ad Revenue Report FY2024). With that much money sloshing around, the competition is brutal. You can't outbid everyone, but you can out-write them.

The Counter-Argument: Targeting Is King

I know what the skeptics are thinking: "Creative is nice, but targeting is what actually matters." And sure, if you show a great ad to the wrong person, it's useless. But here's the thing—targeting has gotten easier, and creative has become the differentiator. With Performance Max, you can reach customers across all Google's inventory, and the machine learning sets bids and finds audiences for you (Google Ads Help (Performance Max)). So the targeting is largely automated. What's not automated is the human touch of writing an ad that makes someone stop scrolling and click.

Even with the most sophisticated Smart Bidding strategies, like Target CPA or Target ROAS, the algorithm can only optimize for what it can measure. It can't make your ad copy better. That's on you. And the stakes are higher than ever. The average CTR for paid search is only 2-5%, while display is a pathetic 0.1-0.5% (Google Ads Help (ad metrics)). That means 95% of people who see your search ad don't click. If you can move that needle even a little, you win.

What I'd Actually Do

So, here's my concrete recommendation: stop obsessing over bidding strategies and start obsessing over your headlines. Write at least 15 headlines for every responsive search ad, and make each one count. Use emotional triggers, specific numbers, and a clear value proposition. And don't stop there—test everything. Use ad extensions to add sitelinks and callouts (Google Ads Help (ad extensions)). And remember, the algorithm is your friend, but it's only as good as the creative you feed it.

I'd also recommend embracing native advertising, which is defined as ads that are so cohesive with the page content that the viewer feels they belong (IAB Native Advertising Playbook). That's the ultimate test of copywriting—making an ad feel like it's not an ad. That's where the real money is.

But don't take my word for it. Look at the numbers. The ANA found that only 36 cents of every programmatic dollar actually reaches the consumer (ANA Programmatic Supply Chain Study). That's a lot of waste. Smart copywriting can help you stand out in a sea of mediocrity, and it doesn't cost extra. It's the cheapest optimization you'll ever make.
