How to Write Google Ads Copy that Converts [Updated for 2026]

Google Ads Headline Strategy

Google Ads headlines connect an impression to a click, but businesses often rely on keyword-stuffed copy or generic AI-generated text. The presenter argues that customer-focused copy and disciplined testing can improve campaign results—even with automated bidding and AI in the platform.

Four foundations for ad copy

• Keyword focus: Match the language of the search to the ad. Consider dynamic keyword insertion (DKI) when appropriate.
• A specific call to action: Replace vague prompts such as “Book now” with a verifiable benefit—for example, “Call now to save $49.” Any stated savings or performance claim must be factual and supportable.
• A distinctive selling point: Explain what competitors can’t or won’t offer. This is especially important for higher-priced offers: the ad should give customers a reason to consider them before clicking.
• An emotional trigger: Address the customer’s problem, discomfort, goal, or desired outcome. For example, change “professional accounting services” to “Save 12 hours on your upcoming taxes,” or “best product management tool” to “Ship products two times faster.”

The ad should also set accurate expectations for the landing page. Benefits or qualifiers in the ad can help connect the click to what the visitor encounters next.

Testing process and performance measures

1. Start with two otherwise identical ads, changing only one core element. The presenter’s example compares an ad with a DKI headline pinned in position one against an unpinned version.
2. After identifying a winner, test another single change, such as a different headline or a call to action pinned in position two.
3. Run tests for roughly 30–60 days. Ad-copy tests may overlap with changes to bidding strategies or keyword targeting, so interpret results in context.
4. When a clear winner emerges, pause the losing ad, duplicate the winner, and continue testing one element at a time.
5. Judge ads primarily by conversions and cost per conversion, not just click-through rate (CTR). CTR is useful, but the objective is sales or other valuable conversion actions.
6. Treat ad strength as a diagnostic prompt, not a reliable measure of business performance. In the presenter’s example, the best-performing ad had a “poor” ad-strength rating and a pinned headline.

Results and metrics cited

• In one client example, CTR rose from 4.5% to just under 9% by the end of October, then was regularly above 10% during later testing. The presenter says this supported profitable scaling but provides no revenue or spend figures.
• In a separate comparison, two ads had CTRs of 8.79% and 9.31%. The presenter says one had a significantly lower cost per conversion, but gives no exact cost figures.
• For the unnamed industry in that example, the presenter cites an average CTR of about 7%. They say they first aim to push CTR above 10%, leaving room for a price or service qualifier to lower CTR by around 2 percentage points while keeping it in the 7–8% range.
• A qualifier may lower CTR but still be worthwhile if it improves conversion rate—for example, by filtering out customers who are not a fit for a premium-priced offer.
