Writing Great Ad Copy

Your ad has one job: earn the click. Strong headlines, a clear benefit and a call to action do the heavy lifting.

What you will learn

  • Write headlines that earn clicks
  • Use benefits and a call to action
  • Add ad extensions to take up more space

The click is the goal

Ad copy is the words in your ad. Its only job is to make the right person click (and the wrong person scroll past). Good copy speaks to what the customer wants, not to how great you think you are.

The three ingredients

  • Headline — grab attention and match the search. Put the keyword here.
  • Benefit — what does the customer get? Save time, save money, look great.
  • Call to action (CTA) — tell them exactly what to do next: Book Now, Get a Free Quote, Shop Today.

Weak vs strong — same business

Here is a dental clinic in Lucknow. Look at the difference a rewrite makes.

A full strong ad

Now let us put the three ingredients together into one finished ad for the same dental clinic, and bolt on a few extras at the bottom. Read each line and notice how it earns the click:

A complete dental clinic ad with extensions added
Headline 1:  Painless Dental Care, Lucknow
Headline 2:  Teeth Cleaning from ₹499
Headline 3:  Same-Day Appointments

Description 1: Gentle, modern dentistry by experienced doctors.
Description 2: Book online in 2 minutes. Free first check-up.

Sitelinks:   About Us  |  Our Services  |  Patient Reviews  |  Contact
Callout:     20+ Years Experience · Open Sundays · EMI Available
Call:        Tap to call 0522-XXXXXXX

Note: The extra lines at the bottom are ad extensions. Sitelinks add clickable links, callouts add short selling points, and a call extension lets people tap to call. They make your ad bigger and give people more reasons to click — usually for free.

What are ad extensions?

Extensions are extra bits you bolt onto an ad to make it take up more space and offer more. The main ones:

ExtensionWhat it addsExample
SitelinksExtra clickable linksAbout · Services · Reviews
CalloutsShort selling pointsOpen Sundays · EMI Available
CallA tap-to-call buttonTap to call the clinic
LocationYour address on a mapShows your shop nearby

Tip: Write at least 3 different headlines so Google can test which works best. And always include a number or offer when you can — ₹499, 30% off, Free Quote — specifics beat vague promises every time.

Watch out: Never write a headline that promises something the landing page does not deliver. If the ad says ₹499 cleaning and the page shows ₹1500, people bounce, you waste the click, and trust is gone.

Q. What is the single job of your ad copy?

Answer: Ad copy exists to earn the click from the right customer. Headlines, a clear benefit and a strong call to action all serve that one goal.
