In Google Ads, a few lines of copy decide whether your budget finds customers or vanishes. These are the Google Ads copywriting methods our team uses every day to write ads that match what people are searching for, earn the click, and turn a search into a customer, without wasting your budget.
Why Google Ads Copywriting Matters
Google Ads copywriting is the craft of writing the short lines of text that appear in Google search results and persuade the right person to click. It sounds simple, but a handful of words decides whether your budget buys customers or just impressions. Strong copy lifts your click through rates, improves your Quality Score, and lowers what you pay for every visit, while weak copy quietly burns money you will never see again.
There is very little room for a wasted click. Google holds roughly a 95.37% share of the mobile search market, and around 83% of landing page visits now come from mobile devices, so your ad is usually the first thing a customer sees on a small screen with plenty of competition one scroll away. On a crowded results page, the ad that speaks most directly to the search wins the click, and the click is where everything else begins.
Our Approach: We treat every ad as a promise. The copy has to mirror the user’s search query, make one clear point, and lead to a landing page that honours it. We write for the human first and the algorithm second, then let Google Ads experiments settle any argument about which version works. Clever wording that does not convert is not clever at all.
Since 2017 our Perth Google Ads team has written and tested thousands of ads across google search ads, google shopping ads and everything in between. What follows is the practical playbook we use for writing Google Ads copy that earns clicks and, more importantly, customers. We will be honest: few things frustrate us more than auditing an account and finding thousands of dollars poured into ads that never stood a chance. It is heartbreakingly common, and almost always fixable.
● 95.37%: Google’s share of mobile search
● 83%: of landing-page traffic is now mobile
● 30 / 90: character limits for headlines and descriptions
Start With Your Audience And Search Intent
Great ads start long before the writing. They start with understanding the target audience and the exact moment they are searching. Every search query carries an intent, a reason behind the words, and the closer your ad copy sits to that intent, the more relevant it feels and the more it gets clicked.
We map the pain points, the questions and the language your potential customers actually use, then group them so each ad group speaks to one clear need. A person in Joondalup typing “emergency plumber near me” wants speed and availability, while someone in Fremantle searching “bathroom renovation quotes” is comparing options. Writing the same generic line for both wastes the click. Matching your message to search intent is the single biggest lever in Google Ads copywriting, because relevance is what Google rewards and what prospective customers respond to.
This is also where audience targeting earns its place. Beyond the search term itself, we layer in signals like location, device and the time of day people search, so the same google ad copy can flex to the context. A late-night search on a phone often signals urgency, and the copy can lean into that, while a weekday desktop search may want detail and reassurance instead. Understanding who is searching, and why, turns a decent ad into a relevant one.
Know The Anatomy Of A Google Ad
You cannot write well within a format you do not understand. Whether you are writing Google Ads copy for classic google search ads or refining search ads copy for a new product line, the format sets the rules before you write a word. Most modern text ads are responsive search ads, where you supply a pool of assets and Google assembles them in real time to suit each user’s search query.
The space is tight, which is exactly why every word counts. You can provide up to 15 headlines and four descriptions, and Google shows up to three headlines and two descriptions in any given ad. Headlines can be up to 30 characters long, and descriptions up to 90 characters each. Within that space you need relevant keywords, a clear benefit and a reason to act, all while sounding like a human rather than a slot machine of phrases.
Google grades the result with an ad strength score, running from poor to excellent. That score is only a guide, not a ranking factor in itself, but it is a useful nudge: a healthy mix of unique headlines and descriptions gives the system more room to find winning combinations. We aim for genuine variety across the assets rather than fifteen ways of saying the same thing, since that is what lets the machine do its job.
Write Headlines That Earn The Click
Your headlines carry the ad, so writing headlines deserves the most care of anything you do. The first headline should mirror the search term as closely as it honestly can, because an ad that echoes the words someone just typed feels instantly relevant. Thoughtful keyword placement in that opening line lifts both ad relevance and your Quality Score.
Beyond that first headline, the best ad copy headlines lead with clear benefits and unique selling points rather than vague claims. Specific beats generic every single time.
● Lead with benefits: tell people what they gain, so “Cut Your Power Bill By 40%” beats “Quality Solar Panels”.
● Use real numbers: meaningful figures and specific claims read as far more credible than round, empty promises.
● Show your unique selling points: highlight what sets you apart, whether that is same-day service, free quotes or a local guarantee.
● Add a clear call to action: at least one headline should spell out the next step.
Write each headline so it can stand alone, since Google may show them in different orders, yet make sure they still read as coherent messages when they appear together. Compelling headlines that work both ways give the system freedom to test combinations while still sounding like your business rather than a random shuffle of words.
Write Descriptions That Persuade
If headlines win the glance, your description copy wins the click. This is where you back up the promise with the detail people need to feel confident enough to act. Good descriptions expand on your key benefits, answer the obvious objection, and finish by telling people exactly what to do next.
Persuasion here is concrete, not loud. Social proof such as review counts, years in business or the number of local customers served builds trust in a line or two, and the right way to create urgency, an offer ending soon or limited availability, gives people a reason to act now rather than later. Used honestly, urgency nudges; used cheaply, it erodes trust, so we keep it real.
We test different value propositions in the descriptions constantly, because the angle that resonates is often not the one you would guess. One audience responds to price, another to speed, another to a guarantee. A description that names a real benefit and a real reason to click will always outperform one that simply lists features, which is why we treat the description as an argument, not a summary.
Google Ads Copy Templates To Start From
Templates are not a substitute for thinking, but they are a fast way to start producing Google Ads copy that already follows the rules. We keep a small library of google ads copy templates for headlines and descriptions, then adapt each one to the client, the keyword and the offer rather than pasting it in blindly.
A few reliable headline structures we return to whenever we write copy for a new campaign:
● Keyword plus benefit: “[Service] In [Suburb], Done Right” puts the search term and the promise in one line.
● Number plus proof: “Trusted By 2,000+ Perth Locals” turns social proof into a headline.
● Offer plus urgency: “Free Quote, Booked Today” pairs a clear offer with a reason to book today.
● Question plus answer: “Need It Fast? Same-Day Service” mirrors a worried search and resolves it on the spot.
The same thinking shapes description copy: open with the benefit, add a specific proof point, and close with a clear call. Treat every template as a starting line rather than a finish line, and always keep it relevant copy for the exact search sitting behind it. A template gets you moving; the edit is where the ad becomes yours.
Use Keywords Without Stuffing
Keywords in your ad copy do two jobs at once. They tell Google your ad is relevant, which supports your Quality Score, and they reassure the searcher they are in the right place. Including your main keyword in a headline and again in a description is often enough to lift click through rates noticeably, because the ad visibly matches the search.
The trick is to weave relevant keywords in naturally, in lines that still read like a human wrote them. Whether you call it keyword optimise or keyword optimize, the rule is the same: aim for one clear use of the term per asset, not five. When you write ad copy, relevance beats repetition every time. Keyword stuffing does the opposite of what people hope: cramming the same phrase in repeatedly reduces ad quality, hurts user engagement, and reads as spam to the very people you want to impress.
For campaigns built on many tightly themed keywords, dynamic keyword insertion can help. This dynamic ad feature automatically slots the user’s search term into your headline so a single ad matches more queries. It is powerful, but it needs sensible default text and a careful eye, because an unedited insertion can produce an ad that reads awkwardly, breaks a character limit, or promises something you do not actually offer.
Get The Most From Responsive Search Ads
Responsive search ads reward variety. Because Google tests combinations of your assets, the more genuinely different your headlines and descriptions are, the more the system has to work with. Writing ten headlines that all say the same thing in slightly different words gives it nothing useful to test, so we deliberately write across angles: price, speed, trust, guarantee, location and outcome.
Pinning is the feature people most often get wrong. You can pin headlines to a fixed position, which is useful when a legal line or your brand name must always appear, but excessive pinning strips away the very testing that makes responsive search ads work. We pin only when we must, leave the rest free, and let the system explore. Ignoring Google’s guidelines on unique assets here is a common way to quietly cap your own performance.
From there, Google Ads experiments and ad variations reveal which messages actually earn the click. Testing different angles, rather than just tweaking wording, is what produces real gains, and it is far more reliable than guessing which clever line will land. The copy you were sure would win is often beaten by the plain one that simply matched the search.
Add Ad Extensions For More Real Estate
Ad extensions, now called assets, are the copy enhancing features that make your ad bigger, more useful and more clickable at no extra cost per click. They give prospective customers more reasons to choose you and more ways to act, and they are one of the easiest wins in any google ads campaign.
● Sitelink extensions: add multiple links to specific pages, such as Pricing, Contact or a key service.
● Callout extensions: highlight short, punchy features like “Free Quotes” or “Family Owned”.
● Structured snippets: present categorised information, such as the brands you stock or the services you offer.
● Promotion extensions: advertise a discount or special offer directly in the ad.
● Location extensions: show your address and put you on the map for nearby searches, which matters for local Perth businesses.
Used together, these assets can nearly double the size of your ad and give people the information they need before they even click. We add every relevant extension to every campaign as a matter of course, because leaving them off is like buying a billboard and using half of it. More useful information means higher relevance and stronger click through rates.
Match Your Ad To The Landing Page
The click is only half the job. If your ad promises free same-day quotes and the landing page opens with a generic homepage, the visitor feels the mismatch immediately and leaves. That broken promise erodes trust, wastes the click you paid for, and drags down your Quality Score, since Google measures how well your landing page copy matches both the ad and the search behind it.
We write the ad and the page as one message. The headline a customer clicked should be echoed at the top of the landing page they arrive on, with the same benefit and the same call to action carried straight through. When the ad, the keyword and the page all line up, conversion rates climb and your cost per lead falls, often dramatically.
We use Google Analytics to watch what people do after the click, not just whether they clicked. An ad that earns clicks but no conversions is a problem the copy and the page have to solve together, and the data usually shows exactly where the story breaks down. Fixing that seam is often the fastest win in an entire account.
Write Mobile-First Ads
With most landing page visits now happening on a phone, mobile-first ads are no longer optional. Mobile users scan fast, often on the move, so your copy has to be quick to read and highly relevant in the first few words. Front-load the benefit and the keyword, and never bury the point in the back half of a headline that may get truncated on a small screen.
Mobile-first ads also lean harder on assets that suit a phone. A call extension that lets someone tap to ring you, a location extension that opens the map, and short, scannable descriptions all make the experience effortless. Optimising ads for mobile improves click through rates and campaign relevance, simply because you are meeting people the way they actually search rather than the way a desktop mockup suggests. Even the way a phone number displays matters, since a tappable number turns intent into a call in a single motion.
Do Not Forget Google Shopping Ads
For retail and ecommerce, google shopping ads work differently from search ads, but copy still matters enormously. Shopping ads pull from the product feed you manage in Google Merchant Center rather than written headlines and descriptions, so your product titles and descriptions become your ad copy whether you meant them to or not. Increasingly that same feed also powers Performance Max campaigns, which makes clean, keyword-rich product data matter more than ever.
The same rules apply. Lead with the words people search for, include the details that drive a decision, and keep it relevant. Strong product titles that front-load brand, product type and key attributes help your listings appear for relevant search results in the shopping tab and win the click against similar items sitting right beside you. Treating your feed as copy, not an afterthought, is what separates shopping campaigns that sell from those that simply spend. A few extra words in a product title, matched to how people really search, can be the difference between a listing that sells and one that is scrolled straight past.
Common Google Ads Copywriting Mistakes To Avoid
Most underperforming accounts are not missing a clever trick; they are repeating the same avoidable mistakes. Knowing what drags a campaign down is half the battle when you are creating ads that have to earn their keep against real competitors.
● Generic messaging: vague lines that could belong to any business lead to disengagement and low click through rates.
● Keyword stuffing: repeating a phrase to game relevance reduces ad quality and user engagement rather than lifting it.
● Weak calls to action: a soft or missing call fails to encourage users to act, so the click never comes.
● Ignoring Google’s guidelines: ignoring Google’s guidance on unique assets and dynamic features leaves conversions on the table.
● Ad and page mismatch: when the ad and its landing page disagree, trust collapses and the budget is wasted.
The fix for all of them is the same discipline we have described: write specific, relevant copy, follow the platform’s best practices, and let evidence rather than ego decide what runs. Across the multiple campaigns we manage, the accounts that avoid these traps are the ones that quietly pull ahead of their competitors month after month.
Test, Measure And Keep Improving
No one writes the perfect ad first time, and anyone who claims to is guessing. The best ad copy comes from continuous ad copy testing, where real performance settles the debate rather than the loudest opinion in the room. We run structured Google Ads experiments and A/B testing against existing ads, changing one meaningful angle at a time so we can see what actually moved the numbers.
Test value propositions, not just adjectives. Trying “free quotes” against “fixed prices” teaches you far more than swapping one synonym for another. We watch click through rates, conversion rates and Quality Score together in Google Analytics and the Google Ads dashboard, build variations in bulk with Google Ads Editor, and let Smart Bidding handle delivery once the copy is doing its job. We keep the winners and quietly retire the rest before they waste more budget.
This loop, guided by data and grounded in best practices, is how a decent campaign becomes a great one. An AI tool can help draft ad variations quickly, and we use them to get options on the table faster, but the judgement about what to test and what the numbers really mean is where experience earns its keep. Great ads are built, tested and rebuilt, never simply written once and left alone. There is a real buzz, even after years of doing this, in watching one rewritten headline quietly halve what a client pays for each lead by the end of the week.

Frequently Asked Questions
Straight answers to the questions we hear most about Google Ads copywriting and writing ads that get clicks.
How Long Can Google Ads Headlines And Descriptions Be?
Each headline has a 30 character limit and each description a 90 character limit. Responsive search ads let you load a pool of assets, up to fifteen headlines plus four descriptions in total, with Google showing only a few in any single ad.
How Do Keywords Improve Ad Copy?
Using relevant keywords in your headlines and descriptions improves ad relevance and Quality Score, and it reassures searchers they have found the right result. The key is to include them naturally rather than stuff them, since keyword stuffing hurts both quality and user engagement.
Should We Use Dynamic Keyword Insertion?
Dynamic keyword insertion can lift ad relevance and click through rates by matching the user’s search term, but it needs care. Always set sensible default text and review how it reads, because an unchecked insertion can create an ad that sounds awkward or promises the wrong thing.
Why Are Our Ads Getting Clicks But No Conversions?
Usually the ad and the landing page are not telling the same story. If the copy promises one thing and the page delivers another, people leave. Match your landing page copy to the ad and the query behind it, and use Google Analytics to see exactly where visitors drop off.
How Often Should We Test Our Ads?
Always have a test running. Continuous ad copy testing through Google Ads experiments is how you find your best-performing variations. Change one thing that matters at a time, give it enough data to be reliable, then keep the winner and try the next idea.
Can We Just Use An AI Tool To Write Our Ads?
An AI tool is handy for drafting ad variations quickly, but it does not know your customers, your margins or your market. The best results come from pairing that speed with human judgement about search intent, value propositions and what the results are really telling you.
Turning Better Copy Into More Customers
Google Ads copywriting is not about clever slogans. It is about understanding search intent, writing headlines and descriptions that mirror it, using relevant keywords without stuffing, adding the right extensions, and matching every ad to a page that delivers what it promised. Do that, test it properly, and write for mobile first, and you build a google ads campaign that earns clicks and converts them into customers.
None of it has to happen all at once. Even tightening your headlines, aligning your landing page and setting up a single experiment can lift your click through rates and lower your cost per lead noticeably. That steady, evidence-led work is what our Google Ads management team does for businesses across Perth every day, and it is the difference between an account that spends and one that sells.
