How to Write Google Ads Copy That Gets Clicked

Writing Google Ads copy is a different discipline from writing website content or social media posts. You have a tiny amount of space, a very specific audience, and a single moment to make an impression before they scroll to the next result. Every word has to earn its place.

The good news is that effective ad copy follows repeatable principles. Once you understand what searchers are looking for and how to frame your offer in response, writing ads that get clicked becomes far more systematic than creative.

Match your headline to the search intent

The most important line in any Google ad is the first headline. Searchers typically glance at the headline first and only read further if it grabs their attention. The most reliable way to grab attention is to mirror what the person searched for as closely as possible. If they typed "affordable website design Norwich", an ad that opens with those words immediately signals relevance.

Google allows up to fifteen headlines in a responsive search ad, and the system rotates and tests combinations automatically. Use this to your advantage by including several variations — some that match the keyword closely, some that highlight your key benefit, and some that include a call to action. Let Google’s machine learning determine which combinations perform best for each query.

Avoid vague, brand-led headlines like "Welcome to Our Company" in the top positions. Headlines that name a specific outcome, number, or qualifier consistently outperform generic ones. "Same-Day Callout, No Hidden Fees" gives a searcher something concrete to compare against your competitors.

Make your descriptions do real work

Descriptions appear below the headline and give you more space to explain your offer. Many advertisers waste this space with filler phrases like "we are a leading provider of…" which say nothing a searcher needs to hear. Instead, use the description to resolve the objection most likely to stop someone from clicking.

If price is a common barrier, state your starting price or offer a free quote. If trust is the issue, mention how many customers you have served or include a brief social proof element such as "rated 4.9 stars by 200 clients". If the searcher is urgency-driven, state how quickly you can deliver. Each description should answer: why should I click this ad rather than the one above or below it?

Use all available description characters. Longer descriptions take up more visual space on the page, pushing competitors further down. Even if the extra words only add modest information value, the increased visual footprint alone can lift click-through rates.

Use ad extensions to take up more space and add trust

Ad extensions — now called assets in Google Ads — appear alongside your core ad and add extra lines of information at no additional cost per click. Sitelink extensions let you link to specific pages such as your pricing page, case studies, or contact form. Call extensions display your phone number. Location extensions show your address for local businesses.

Extensions also increase the overall size of your ad on the page, which means more visibility without paying more. Google shows extensions when it predicts they will improve performance, so adding more extensions gives the system more options to work with. A well-set-up ad with six or seven sitelinks and a call extension can occupy significantly more screen space than a competitor running a basic ad.
