The ad text box asks for headlines and descriptions, and most owners fill it the way they would write a shop sign: the business name, a slogan, “quality service”, a phone number. The ad gets approved and runs. It also looks almost exactly like the three ads around it, so the person searching has no reason to pick yours.
This post is about how to write Google Ads that a searcher actually reads and chooses. It covers how responsive search ads are put together, what to put in your Google Ads headlines and descriptions, when pinning helps, and how to keep every claim honest enough to pass review and survive a sceptical reader.
How a responsive search ad is assembled
A standard Search ad today is a responsive search ad. Instead of writing one fixed ad, you give Google a set of headlines and a set of descriptions. Google then mixes them, showing a few headlines and one or two descriptions at a time, and learns over time which combinations people respond to.
That changes how you write. Each line has to make sense on its own and next to any other line. A headline that only works as the second half of a sentence will sometimes appear first, or alone. So write lines that are complete thoughts, not fragments of one long message.
Google also shows an ad strength rating as you write. It encourages variety and the use of your keywords. Treat it as a hint about variety, not a score to perfect. A clear, honest ad rated “good” will often do better for a small business than an “excellent” one stuffed with near-identical phrases.
How to write Google Ads around the search, not the business
Before writing a word, look at the ad group’s keywords and, if the campaign has been running, its search terms. The ad should answer the person who typed them. Someone searching “deep cleaning service for flat” wants to know three things quickly: do you do this, do you do it where I am, and how do I book.
A useful exercise is to write the searcher’s likely question at the top of a page, then write headlines that answer it directly. “Flat Deep Cleaning in Pune” answers the first two. “Book a Visit by Phone or WhatsApp” answers the third.
Google Ads headlines: what each one should do
You do not need every headline slot filled with something different for the sake of it. You need a spread of lines that each do one job. A practical set for a service business covers:
- The service in the searcher’s words. Several variations, since this is what tells them they are in the right place.
- Where you work. The city, area or “serving” a set of localities, if you are local.
- A concrete reason to choose you. Something checkable: evening appointments, home visits, a registered practitioner, a written quote before work starts.
- What happens next. Call, book online, send a WhatsApp message, get a quote.
- Your business name. Useful for people who already know you and for trust.
Avoid lines that could belong to any business: “Quality You Can Trust”, “Your Satisfaction Matters”, “Excellence in Service”. They take up space without telling anyone anything.
Descriptions: the detail that earns the click
Descriptions have more room, and they are where you can add the detail a headline cannot carry. Good descriptions tend to include one or two specifics and an instruction. For a chartered accountant, that might be: “GST filing and returns for small traders. Fixed fee agreed upfront. Call or book a consultation online.”
Write two or three descriptions that differ in focus: one about the service, one about how you work, one about the next step. Then each combination Google chooses still makes sense.
Pinning: use it sparingly
Pinning lets you fix a headline or description to a particular position, so it always appears there. It is useful in a few situations:
- A legal or regulatory line that must always show.
- A headline that must appear first for the ad to make sense, such as the service name in a very specific ad group.
- Keeping the business name in a fixed place if your brand guidelines need it.
Every pin reduces the number of combinations Google can test. Pin every slot and you have effectively written one fixed ad again, which removes most of what responsive ads are good at. If you need to keep something in position, pin two or three alternatives to the same slot rather than one, so Google can still choose among them.
Display path and final URL
The display path is the short, readable part of the web address shown on the ad, such as your domain followed by a word like “deep-cleaning”. It does not have to match the real page address, but it should describe it honestly. The final URL is where the click actually goes. Make it the page for that service, not the home page, and check it loads on a phone before saving.
Honest claims and the policy basics
Google reviews every ad before and after it runs. Most rejections for small businesses come from a short list of habits that are easy to avoid:
- Editorial style. Excess capital letters, repeated punctuation, symbols used for decoration, or gimmicky spelling.
- Claims the page cannot support. A price, offer or feature in the ad that the landing page does not show.
- Unverifiable superlatives. “Best”, “number one” or “cheapest” invite questions and rarely persuade a careful buyer anyway.
- Restricted topics. Health, finance, legal services and some other areas have extra rules, and some need certification or verification before ads can run.
- Trademarks. Using another company’s name in ad text can be restricted.
If an ad is rejected, our post on fixing disapproved ads explains how to read the reason and what to do next. Beyond policy, honesty pays in a simpler way: an ad that promises what the page delivers brings visitors who stay.
Keyword insertion and other shortcuts
Google offers a feature that inserts the matched keyword into your headline automatically. It can make ads look very relevant, but it can also produce odd or ungrammatical lines when the keyword is awkward, and it can insert words you would not choose to show. For a small account with tidy ad groups, writing the service name yourself is usually safer and reads better.
Similarly, automatically created assets and suggested headlines can be handy starting points. Read them before accepting. They are generated from your website and can repeat outdated details or claims.
Testing without fooling yourself
Responsive ads already test combinations, so you rarely need many ads in one ad group. One or two well-written responsive ads per ad group is a common, workable setup. To learn which lines work, look at the asset report for the ad, which shows how often each headline and description was used and how Google rated it.
Change a few weak lines at a time and give the ad several weeks before judging. Judge by enquiries and cost per enquiry, not by clicks alone. A headline that attracts lots of clicks from people who never call is not a good headline. Our post on how Quality Score rates ads explains how ad relevance and expected clicks are judged.
A short worked example
For an ad group about home deep cleaning in Pune, a balanced set of headlines might include “Home Deep Cleaning in Pune”, “Flat and Villa Deep Cleaning”, “Trained Staff, Own Equipment”, “Written Quote Before We Start”, “Book by Call or WhatsApp” and the business name. Descriptions might cover what is included, how booking works, and the areas served. None of it is clever. All of it is specific, and every claim can be checked on the landing page.
Ads also grow with extra lines such as sitelinks and call buttons. Our guide to sitelinks, callouts and call assets covers those, and our overview of Google Ads for beginners shows where ad writing sits in a first campaign.
Frequently asked questions
Should I put prices in my Google Ads?
Only if the price is fixed, current and shown on the landing page. A clear starting price can filter out people looking for something cheaper, which saves clicks. A price that changes often or is not visible on the page risks rejection and annoys visitors, so leave it out if you cannot keep it accurate.
Can I write ads in Hindi, Bengali or another language?
Yes, Google Ads supports many languages. The ad language should match the campaign’s language setting and the landing page, and the people searching. Some businesses run separate ad groups for English and local-language searches. Mixing languages within one ad usually reads poorly, so keep each ad in one language.
How often should I rewrite my ads?
Rewrite when something changes, such as a new service, a changed offer or outdated details, or when the asset report shows lines that are rarely used or rated poorly. Rewriting everything on a fixed schedule resets what Google has learned about your ads, so change a few lines at a time instead.
Ad writing is one of the parts of a campaign you can do well yourself, because you know your customers’ questions better than anyone. If you would rather have ads, assets and landing pages written together and reviewed each month, that is part of our Google Ads management.
