Best practices for writing Google Ads

Here are some fundamental best practices for writing super-effective Google Ads.

Prioritize relevance

The Google Ads algorithm is all about relevance. Make sure your ad copy is super relevant to your keywords and that your landing page is super relevant to your ads. The more continuity there is, the better.

Use keywords in headlines for better visibility

This helps with relevancy, allowing you to match search intent, boost Quality Score (which can lower CPC), and increase CTR. Two quick tips:

  • See if you can use long-tail keywords for high-intent searches. For example, “best metal roof installers for storm protection.”
  • For shorter keywords, place them at the beginning of the headline to ensure visibility.

Use ad assets

Use various ad assets (formerly called “extensions”) to provide additional information and links, enhancing ad relevance and performance.

Popular ones include structured snippets, price, lead forms, sitelinks, location, and call assets.

A/B test

Even with responsive search ads doing the mixing and matching for you, you should still be testing different approaches with your ads. You may even separate them into different campaigns based on an overall theme. After all, you only get so much visibility into the performance of each ad combination within a single RSA campaign.

Some things to test include:

  • Short vs. long-tail keywords
  • Direct vs. benefit-driven phrasing
  • Urgency-focused vs. informational headlines

Tricks for writing high-performing Google Ads

It’s one thing to follow best practices for Google Ads. It’s another to write exceptional Google ads. Here are the techniques to employ, that go beyond best practices, to help you maximize conversions.

Copywriting tricks

Ah, copywriting. I’m in my natural habitat here. I could go on for days, but I’ll keep it short:

  • Use emotion for high-performing headlines. We’ve got over 130 emotional words and phrases for you to browse through, plus these examples of emotional ad copy to inspire you.
  • Use psychological techniques to boost CTR. There are several ways to use psychology in your ad copy. You can appeal to moral values, scarcity, repetition, hyperbole, and more.
  • Use social proof. Leverage testimonial quotes and stats to convey to your audience that others are happy with your product or service. This is the most powerful tool at your disposal.
  • Use power words. Pair your keywords with power words. Examples include “exclusive,” “proven,” “award-winning,” “instant,” “guaranteed,” and “effortless.”
  • Offer the right balance. Use our responsive ad copy template to make sure you’re using the right mix of features, benefits, and pain points.
  • Offer an incentive. The best way to stand out is to offer some sort of tangible incentive, like a discount, a free offer, or a high-demand feature.

Nothing like a little fear-based copy about overpaying to complete your Google ad copy.

CTA tricks

The more specific you are with your call to action, the better. Another pro tip: Tailor your CTA for the intent of your audience. For example:

  • Top of funnel: Learn More, See How It Works, Get the Guide, Explore Solutions
  • Middle: Start Your Free Trial, Compare Plans, See Pricing, Schedule a Consult, Book a Demo
  • Bottom: Talk to an Expert Now, Get Started Now, Sign Up & Save 20%, Order Now & Get Half Off,

“Get dental implants in one day” is highly specific. Plus, this example has a nice nod to the importance of experience.

Keyword tricks

Try dynamic keyword insertion. This feature will automatically insert the exact search term into the headline. For example: “{KeyWord: Custom Window Installation} – Get a Free Quote.”

But you need to be careful with your template for this one because you can get some awkward phrasing. For example “Need Fix Leaky Faucet Myself? Call Now!” or “Get Cheap Roofing Companies Near Me.” These will convey carelessness and disingenuousness (sidenote: wow, I thought for sure autocorrect was going to tell me this isn’t a word. I’m pumped).

Targeting tricks

With some Google Ads campaign types (Performance Max especially), you can upload customer lists, email lists, CRM data, past purchase behavior, and more for more precise targeting and therefore more precise ad copy. What’s more, this is all first-party data, which is accurate, privacy-compliant, and insight-rich. Here are some examples:

  • Existing customers → cross-sell to existing customers, promote a special offer to VIP customers, reengage dormant customers
  • Existing leads → win back old leads who visited your website or who booked a demo but never closed
  • Website visitors → retarget people based on pages they visited or cart behavior

Well-written Google Ads copy examples

Here are some examples of Google Ads that employ the best practices and techniques we’ve covered:
