Most small businesses spend months figuring out how to make ads before they run a single campaign. By the time they do, they have already made the most expensive mistakes — wrong match types, no negative keywords, bids set arbitrarily and never touched again.
This article walks through exactly how to make ads on Google that generate real returns, from initial setup through ongoing optimisation — and explains why the management of those ads matters just as much as building them.
How to Make Ads on Google: The Foundation
Learning how to make ads on Google starts with understanding what you are actually buying. Google Ads is a pay-per-click auction. You bid on keywords, write ad copy, and pay when someone clicks. The cost per click is determined by your Quality Score — a Google-assigned rating based on your expected click-through rate, ad relevance, and landing page experience — multiplied against your maximum bid.
A high Quality Score means you can pay less per click than a competitor while still appearing above them. This is the single most important mechanical fact to understand before you build anything. If you ignore it, you will overpay indefinitely. If you optimise for it from the start, your cost per acquisition drops without your budget having to increase.
You can read more about what SMEs actually pay on Google Ads before committing to a budget. It is worth knowing the landscape before you set your first bid.
Set Up Your Google Ads Account Properly
Go to ads.google.com and create an account. Do not let Google's guided setup push you into a Smart Campaign. Smart Campaigns remove most of the control you need to optimise effectively. Select the Expert Mode option when prompted.
Once inside, link your Google Analytics property and your Google Search Console account. This gives you conversion data and organic search data in the same interface, which makes budget decisions significantly more rational. Without this, you are flying blind on what the click actually did after it landed.
Understand Campaign Types Before You Build
Google offers several campaign types. For most SMEs learning how to make ads for the first time, Search campaigns are the correct starting point. You show text ads to people who are actively searching for what you offer. The intent signal is already there — you are not interrupting someone, you are answering a query.
Display campaigns, Shopping campaigns, and Performance Max all have their place, but they require more data and more budget to work efficiently. Start with Search, prove the economics, then expand.
| Campaign Type | Best For | Minimum Monthly Budget (Approx) | Learning Period |
|---|---|---|---|
| Search | High-intent buyers | £500–£1,000 | 4–6 weeks |
| Shopping | Ecommerce product listings | £500–£1,500 | 4–8 weeks |
| Display | Retargeting, awareness | £300–£800 | 6–10 weeks |
| Performance Max | Multi-channel, data-rich accounts | £1,000+ | 6–8 weeks |
Building the Ad: Copy, Keywords, and Match Types
Once your campaign structure is set, the actual creative work begins. A Google Search ad has three headline slots (up to 30 characters each), two description slots (up to 90 characters each), and various ad extensions — now called assets — that expand your listing with additional links, callouts, and structured snippets.
Every headline should do one of three things: state the problem being solved, state your differentiator, or state a clear call to action. Generic headlines like "Welcome to Our Website" destroy Quality Score. Specific headlines like "Same-Day Boiler Repair London" or "10% Off First Order — Free Delivery" pull click-through rate up and signal relevance to Google's algorithm simultaneously.
Keywords: The Part Most People Get Wrong
Keyword selection determines who sees your ad. Most beginners use broad match keywords, which gives Google permission to show your ad for loosely related searches, including irrelevant ones. We spent nine years at our agency watching new clients come to us having burned through budgets on broad match terms with no negative keyword lists. It is an extraordinarily common and avoidable problem.
Start with phrase match and exact match. Phrase match shows your ad when someone's query includes your keyword phrase, in order, with other words around it. Exact match shows your ad only when the query closely matches your keyword. Both give you far more control than broad match during the early stages of a campaign.
Build a negative keyword list from day one. Search through the search terms report after your first week of running and add any irrelevant queries as negatives. This is not optional — it is one of the core disciplines of running Google Ads well.
Landing Pages Matter More Than the Ad Itself
This is the opinion that rarely appears in generic guides on how to make ads: your landing page is more important than your ad copy. If your ad promises "Affordable Solicitors in Manchester" and your landing page is a generic homepage with no mention of location or pricing, your Quality Score suffers, your bounce rate climbs, and your conversion rate collapses.
The landing page should directly continue the conversation started in the ad. Same language, same offer, a single clear next step. One action per page. How to advertise your business with Google Ads covers the full funnel in more depth if you want to go further on this.
How to Make Ads Work Over Time: Ongoing Management
Building an ad is the easy part. What most guides on how to make ads skip entirely is what happens after you press publish. Google Ads is not a set-and-forget channel. Bids need adjusting. Underperforming ad variations need pausing. Budget needs shifting toward campaigns generating the lowest cost per conversion.
In a well-managed account, you are looking at the search terms report weekly, adjusting bids based on device, time of day, and audience performance, testing new ad copy against existing copy, and making sure your budget is weighted toward what is actually working. Without this, an account that started well will decay over weeks and months as costs creep up and relevance drops.
For SMEs without a dedicated marketing team, this is where things fall apart. It is not that the task is impossible — it is that it is time-consuming, requires genuine familiarity with the interface, and has to happen consistently to make a difference. Google Pay Per Click management is a discipline in its own right.
What Good Account Optimisation Actually Looks Like
A practitioner managing a Google Ads account week to week is doing the following: checking impression share to understand whether budget or Quality Score is limiting reach; reviewing auction insights to see which competitors are gaining ground; adjusting bid modifiers for mobile if mobile traffic is converting at a different rate to desktop; and A/B testing headlines to improve click-through rate over time.
This is operational work. It requires logging in, reading data, making decisions, and executing changes — not once, but continuously. If you want to understand the economics before committing to management costs, how much Google Ads costs for SMEs is worth reading first.
When Manual Management Stops Being Practical
There is a threshold at which manual management becomes impractical. Once an account has multiple campaigns, each with multiple ad groups, keyword lists, and asset combinations, keeping everything optimised by hand is a significant time commitment. Missing a week means bids drift, budgets misallocate, and costs rise.
This is where Overtime operates. It is an AI agent that logs into your Google Ads account, adjusts bids, pauses underperforming keywords and ads, reallocates budget toward what is working, and sends you a plain-English summary of what it did and why. You stay in control of the strategy; it handles the execution.
Common Mistakes That Waste Budget
After nine years running campaigns across dozens of industries, the mistakes we saw repeatedly were not exotic. They were the same handful of errors, made by different businesses, for the same reasons.
First: not installing conversion tracking before launching. If you do not tell Google what a conversion is, it cannot optimise toward one. This sounds obvious, and yet a significant proportion of small business accounts are running without it configured correctly. Second: letting Google automatically apply recommendations without reviewing them. Many automatic recommendations increase spend without improving performance. Third: ignoring the search terms report. Your keywords tell Google what to target; the search terms report tells you what Google actually targeted. These are often different, and the difference costs money.

How to Make Ads in 2026: What Has Changed
Google Ads in 2026 is a materially different product to what it was five years ago. Responsive Search Ads are now the only standard text ad format. Performance Max campaigns have expanded significantly and now draw on more of your first-party data. AI-driven bidding strategies — Target CPA, Target ROAS, Maximise Conversions — have become far more effective as Google's models have matured, but they still require clean conversion data and adequate budget to learn properly.
The fundamentals of how to make ads have not changed: clear intent targeting, strong ad copy, a relevant landing page, and consistent management. What has changed is how much of the optimisation work can be automated without losing performance — and for SMEs, that shift is significant. Overtime's approach to Google Ads management is built around this reality: human strategy, AI execution.
If you are weighing up approaches, Pay Per Click software versus AI agent is a useful comparison of the options available.

The most useful thing you can do today is open your Google Ads account — or create one — and start with a single Search campaign, one tight ad group, ten to fifteen closely related keywords on phrase or exact match, and a landing page built specifically for that campaign. Get that working, track your conversions, and build from there. If the management side becomes the bottleneck, see how Overtime handles it — it was built precisely for businesses that have figured out how to make ads but do not have the capacity to manage them every week.

Frequently Asked Questions
How do I make ads on Google for the first time?
Create a Google Ads account in Expert Mode, not Smart Campaign mode. Start with a Search campaign, choose phrase or exact match keywords related to what you sell, write specific ad copy that matches your landing page, and install conversion tracking before you spend anything.
What is the minimum budget needed to make Google Ads work?
For Search campaigns, a monthly budget of £500 to £1,000 gives the algorithm enough data to begin optimising meaningfully. Below that, you may not generate enough clicks to identify patterns or reach statistical significance on conversion data.
Why are my ads not converting despite good click-through rates?
A high click-through rate with poor conversions almost always points to a landing page problem. The page may not match the ad's promise, may have too many exit routes, or may be loading too slowly. Check that the landing page continues the specific conversation the ad started.
Should I use automated bidding or manual bidding?
Manual CPC gives you the most control early on, but automated strategies like Target CPA or Maximise Conversions outperform manual bidding once you have at least 30 to 50 conversions per month recorded. Before that threshold, automated bidding has insufficient data to make good decisions.
Can an AI agent manage my Google Ads instead of a human?
Yes. An AI agent can log into your account, analyse performance data, adjust bids, pause underperformers, and reallocate budget — tasks that would otherwise require a trained person spending several hours per week. The key difference from basic automation is that an AI agent operates across the full account and explains its decisions, not just executes rules you pre-define.
