Google Ads headline character counter
Each headline in a Google responsive search ad is limited to 30 characters. A single ad can hold up to 15 of these 30-character headlines, and Google mixes and matches them with your descriptions to assemble the live ad. Spaces and punctuation count toward the 30, and dynamic insertions such as a location or keyword can push a headline over the limit at serve time even when your static text fits, so headlines need real headroom, not a tight squeeze against 30.

Google Ads headline character limit guide
Thirty characters, fifteen headlines, one ad
Google responsive search ads do not work like the old expanded text ads, where you wrote one fixed combination. Instead you supply a pool of up to 15 headlines and up to 4 descriptions, and Google's system tests combinations and shows the ones it predicts will perform best for each query, device, and auction. Every one of those 15 headlines is capped at 30 characters, including spaces and punctuation. That tiny budget is the defining constraint of paid search copywriting: you have to land a benefit, a keyword, or a call to action in roughly five short words.
Because Google assembles the visible ad from your pool, the headlines have to read well both alone and in combination. Two or three of them can appear together, separated by a vertical bar, so a headline that depends on the one before it can look broken when Google pairs it with something else. Write each 30-character headline as a self-contained idea. The counter above measures the exact character cost of each line so you can see immediately whether Free Next-Day Delivery fits or has to become Free Next-Day Shipping.
Why you should not write right up to 30
Hitting exactly 30 characters feels efficient, but it is risky. Many advertisers use dynamic keyword insertion or location insertion, where Google swaps in the searcher's query term or city at serve time. If the inserted text is longer than your placeholder, the headline can blow past 30 and Google falls back to your default text, which may not be what you wanted. Leaving a few characters of slack means your headlines survive insertion and a wider range of queries without surprises.
There is also a readability cost to cramming. A headline packed to the edge often relies on abbreviations and dropped words that hurt clarity and quality score. Google rewards relevance and expected click-through rate, and a clear Get A Free Quote Today often beats a cramped Free Quotes Fast Now Online that technically fits. Use the full pool: write several distinct angles, some keyword-led, some benefit-led, some with a call to action, and let Google test them. The counter helps you keep each one clean and under the limit while you focus on variety.
Writing headlines that fit and convert
The most reliable 30-character headlines do one job each. Mirror the search query with a keyword headline so the ad feels relevant, state a single concrete benefit such as a price, a guarantee, or a speed claim, and give at least one clear call to action like Shop Now, Get A Quote, or Start Free Trial. Numbers are your friend in a tight space because they are compact and credible: Save 20% This Week is shorter and stronger than Big Discounts Available Now. Title case reads as ad copy and uses no extra characters over sentence case.
Avoid wasting characters on filler and punctuation Google may strip anyway, such as excessive exclamation points, which its policies limit. Spell out only what earns its space. Before you push a campaign live, paste every headline through the counter above to confirm all 15 sit at or under 30 characters, leave a little room if you use insertion, and read the headlines in a few pairings to make sure any two of them still make sense side by side. Clean, varied, on-limit headlines give Google's optimization the raw material it needs and keep your ads out of the disapproval queue.
