How to write Google Ads copy that actually converts

The best Google Ads copy for local businesses does three things in the headline: names the service, includes the location, and gives a reason to choose you over the next listing. The description adds trust signals and a clear call to action. That’s it. No cleverness. No wordplay. Just clarity and specificity that matches what the searcher typed.

The rules that work.

Match the headline to the search.

If someone searches “emergency plumber Allen TX,” your headline should say “Emergency Plumber in Allen TX.” Not “Quality Plumbing Solutions” or “Your Trusted Plumbing Partner.” Match the words they typed. When the searcher sees their exact query reflected in your headline, click-through rates increase significantly because it confirms your ad is relevant to their specific need.

Put the differentiator in the headline, not the description.

Most people only read headlines. Your competitive advantage needs to be there. “24/7 Emergency Service,” “Same-Day Appointments,” “Licensed & Insured Since 2005,” “Free Estimates,” “No Hidden Fees.” Pick the one thing that matters most for the search and put it in a headline. The description is for supporting details. The headline is what earns the click.

Use numbers wherever possible.

“Serving 500+ DFW Families” is more persuasive than “Trusted Local Service.” “4.9 Stars on Google” is more persuasive than “Highly Rated.” “Appointments Within 2 Hours” is more persuasive than “Fast Service Available.” Numbers are specific. They’re credible. They stand out in a page full of vague claims.

Write descriptions that build trust and drive action.

The description has two jobs: give the searcher confidence that you’re legitimate, and tell them exactly what to do next. “Licensed & insured. 200+ five-star reviews. Free estimates, no commitment. Call now for same-day service.” That description checks every box: credentials, social proof, risk reduction, and a clear CTA.

Pre-qualify to reduce wasted clicks.

At $5-15 per click, you don’t want everyone clicking. You want the right people. If you only serve a specific area, mention it: “Serving Allen, Plano & McKinney.” If you require a minimum project size, hint at it: “Residential Projects $2,500+.” If you don’t offer a service people commonly search for, clarify: “Repair & Replacement. No New Construction.” Every unqualified click you prevent saves $5-15.

Common mistakes that waste ad spend.

Being vague: “Quality service at affordable prices” says nothing. Every competitor says the same thing. Be specific about what you do, where you do it, and why you’re the choice.

Not using ad extensions: site links, callout extensions, call extensions, and location extensions take up more space in search results and provide additional reasons to click. Use every extension available.

Using the same ad for every keyword: “AC repair near me” and “AC installation cost” are different searches with different intents. The repair searcher needs urgency (“Same-Day AC Repair”). The installation searcher needs information (“Free AC Installation Estimate. Compare Systems.”). One ad doesn’t serve both.

Forgetting the mobile experience: over 70% of local searches happen on mobile. Your ad needs a click-to-call option. If the ad leads to a landing page, that page must load in under 2 seconds on a phone with a tap-to-call button visible immediately.
