Your ad competes in the results with several others, and a person has a second to choose. That second is won by copy that says exactly what the searcher wants — and by extensions that take up more space and give more reasons to click. The good news: most of this is free, the only question is skill.
In short: A good Google Ads ad starts from the searcher’s intent: keyword in the headline, a concrete benefit, a reason to choose you and a clear call to action. Extensions (sitelinks, callouts, structured snippets, prices and more) are free, take up more space in the results and raise CTR. Together they improve Ad Rank and can lower your cost per click. Rule: one ad group = one theme, at least 2–3 ads for testing.
Copy starts with intent, not with you
The most common mistake is writing the ad from your point of view, not the searcher’s (“We’ve been on the market 20 years”). The person cares about their problem. Good copy:
- uses the keyword in the headline — when the query and headline match, both CTR and relevance rise;
- shows a concrete benefit, not vague words — “free delivery within 24h”, not “best quality”;
- gives a reason to choose you — speed, guarantee, price, experience, return policy;
- ends with a clear CTA — “Request a quote”, “Book a time”, “See prices”.
Responsive Search Ads: give the system material
Today most text ads are Responsive Search Ads (RSA): you provide several headlines and descriptions, Google combines and tests what works. The more different and relevant variants you give, the better the system can optimise. Don’t put in five nearly identical headlines — give genuinely different angles (benefit, price, speed, trust).
And still: at least 2–3 ads per ad group so there’s something to test. One ad group = one theme, so the copy matches the query exactly.
Extensions (assets): free space and more reasons to click
Extensions (assets) expand your ad in the results — more space, more information, more reasons to click. They’re free and almost always worth it. The main ones:
- Sitelinks — extra links (“Prices”, “Contact”, “Services”) that go straight to subpages.
- Callouts — short advantages (“Free delivery”, “24h support”, “5-year guarantee”).
- Structured snippets — a list of categories or services.
- Phone, location, prices, promotions — depending on context.
Add every extension that suits your business. The more relevant information, the bigger and more convincing your ad — and the better the expected CTR.
How extensions affect cost
Extensions aren’t just for looks. They influence Ad Rank and expected CTR — which through Quality Score can lower your cost per click and raise your position. Simply put: good copy + complete extensions = more clicks for the same money and often a cheaper click. It’s one of the few places where “free” really means a free win.
Common mistakes
- Copy about you, not the customer — nobody clicks “20 years on the market”.
- Vague words — “best quality” says nothing; give a concrete number or fact.
- No call to action — the person doesn’t know what to do.
- Extensions not added — you leave free space and CTR unused.
- Too broad an ad group — one ad can’t answer ten different keywords. Choosing the right keyword match types and structure helps.
AI writes the text, but not the soul
More and more you see ads that look straight off a copying machine: AI has assembled the texts, but there’s no soul in them. The words are grammatically correct and utterly empty — because the machine doesn’t know your business. AI is a good assistant but a poor author when it alone decides what you sell.
Good advertising is born differently. Done properly, a specialist always shows the finished ad to the client for review and approval — because only the business owner knows the real nuances of their business. If the owner is competent, they know all the details no external copywriter or AI knows, and only together with them can you build a structure that truly sells.
Think for yourself what the result is when a serious company turns to amateurs who had AI assemble the text without understanding the essence of the business. The words appear on screen — but no sales come. The best advertising is born not just under an “advertiser’s” hand, but under the hand of someone who has walked the business path themselves — preferably successfully. Only that way can it be done truly well.
We treat the client’s business as our own
Here’s a story. As an experiment, we had a few ads made through a well-known, “leading” agency — just to see how they work. A month later they proudly call: “Look at the result from our advertising!” We ask: what are you celebrating — you didn’t even set up conversion tracking? The answer was “well, that’s something we can discuss”. Discuss what? That should have been said right away.
Another story from the same series. An agency wanted to hand a client over to us — we started looking into it. They assured us the advertising was “ultra-effective”. We asked for the reports, which they weren’t keen to share — and there was, to put it mildly, a horror show. A legal translation company, 10 years on the market, up to 10 leads a day, but for some reason deciding to leave. We look at the account: conversions not set up, no GTM, no GA4 — nothing. First question: if you’re such a great agency, where are the conversions?
It got worse. There were about 100 keywords, and one of them was simply the generic word “translator”. Who searches that? Someone wanting a free or any translator, not legal translations. That one wrong keyword burned €200 a month — for ten years straight. Think for yourself how much money simply went up in smoke because nobody checked whether the keyword brings the right person.
You feel for the client, and such agencies should simply be driven out of the market. And the most interesting part: in their own opinion, everything was fine. That’s exactly the difference — for us “everything’s fine” doesn’t arrive until conversions are in place and every euro works toward the client’s real result. We treat the client’s business as if it were our own. Every purchase and every conversion matters to us as much as it does to the client.
The honest verdict
Ad copy and extensions are where a little skill brings a big win — often without raising the budget. Relevant copy that speaks the customer’s language, plus all suitable extensions, raises CTR, improves Ad Rank and brings more clicks for the same money. But it only works alongside a good structure and landing page — the ad brings the person, the rest is decided by where they land.
