Key facts
- Google Ads works best where people search with buying intent, such as trades, legal services and local clinics
- Work out your break-even cost per lead before spending: profit per sale divided by leads needed to win one
- You pay per click and usually less than your maximum bid: only what is needed to hold your Ad Rank (Google Ads Help)
- Without conversion tracking you cannot tell whether Google Ads is worth it
- Microsoft Ads can import Google campaigns and often reaches the same intent at a lower volume
- dijitul manages Google Ads from £150 a month + VAT, or 10 to 15% of ad spend, whichever is higher
When Google Ads is usually worth it
Google Ads puts you in front of people at the moment they search. It pays off when:
- Demand already exists. People type what you sell into Google: "boiler repair Derby", "conveyancing solicitor", "dog grooming near me". Keyword Planner will show whether there is search volume in your area.
- A sale is worth enough. The profit from a customer comfortably covers several clicks and a few enquiries that do not convert.
- You can answer quickly. Leads from search go cold fast. Someone needs to pick up the phone or reply the same day.
- Your landing page converts. A clear offer, prices or a guide to cost, reviews, and an easy form or click-to-call.
- You can measure it. Calls, forms and sales are tracked as conversions.
When it often is not
- Nobody searches for it yet. A new product category has little search demand. Paid social is often better at creating interest.
- Margins are tiny. If a sale makes a few pounds, competitive click prices can wipe it out. Shopping campaigns with a tight product selection may still work.
- The website is the problem. Ads send people to the page. If the page is slow or confusing, more clicks just cost more. Fix it first, or talk to dijitul web design about a dedicated landing page.
- No tracking. Without it you are judging on gut feeling and phone calls nobody logged.
- Budget too thin to learn. If the budget buys only a handful of clicks a month, you cannot tell good from bad.
Work out your break-even point
Before spending, calculate the most you can pay for a lead:
- Take the gross profit on an average sale, not the sale price.
- Divide by the number of leads it takes to win one sale.
- That is your break-even cost per lead. Aim comfortably below it.
Then check Keyword Planner's top-of-page bid ranges for your keywords and location. If a realistic conversion rate turns those click prices into a cost per lead below break-even, Google Ads is worth testing. If not, consider narrower keywords, a smaller area, a better page, or a different channel. For the budget maths, see how much to spend on Google Ads.
How to test it without wasting money
- Set up tracking first. GA4 key events and Google Ads conversions for forms, calls and sales.
- Start with one tight Search campaign on your highest-intent keywords, using phrase and exact match, with a negative keyword list from day one.
- Target where your customers are, using "presence" location targeting so you reach people in the area.
- Write ads that match the search. Responsive search ads allow up to 15 headlines of 30 characters and 4 descriptions of 90 characters (Google Ads Help).
- Review search terms weekly at first and add negatives.
- Judge on cost per lead and sales, not clicks or impressions.
For local trades, also look at Local Services Ads, which charge per lead rather than per click where available.
If search ads are not the right fit
A "no" to Google Search is not a no to paid marketing. Depending on why the numbers do not stack up, try:
- Paid social when you need to create demand rather than catch it. See Facebook ads.
- Email and remarketing to get more from visitors and customers you already have.
- Microsoft Ads, which can import Google campaigns and is worth testing alongside them.
- Improving the website first, so every future click is worth more.
What it costs with dijitul
Our Google Ads management is from £150 a month + VAT, or 10 to 15% of ad spend, whichever is higher. Ad spend goes directly to Google on your own account. If tracking is missing, conversion tracking is a one-off £145 + VAT.
We will tell you plainly if we think Google Ads is unlikely to work for your business, and what we would try instead. There is no long contract: monthly, cancel with notice. We never promise a number of leads, because nobody controls the auction.
Frequently asked questions
How long does it take to see if Google Ads works?
Ads can start showing once approved, so clicks arrive quickly. Judging whether it is worth it takes longer: you need enough clicks and conversions to compare cost per lead with your break-even figure. For most small businesses that means a few weeks to a few months of tracked data.
Is Google Ads better than Facebook ads for a small business?
They do different jobs. Google Ads captures people already searching for what you sell. Facebook and Instagram ads reach people who match an audience but are not searching yet. Service businesses with clear search demand often start with Google. Products that sell on looks often do well on Meta.
Can I run Google Ads myself?
Yes, and many owners do. The common mistakes are broad keywords without negatives, wrong location settings, Display Network left on in Search campaigns, and no conversion tracking. If you run it yourself, a dijitul audit at £45 an hour + VAT can spot those problems quickly.
Do I need a website to use Google Ads?
Most campaigns send people to a web page, so you need a fast, relevant landing page with a clear way to get in touch. Some formats, such as call-only ads and Local Services Ads, lean on phone calls, but a good page still helps Google judge relevance and Quality Score.
Is it worth it for a very local business?
Often yes, because you can target a tight radius and only pay when someone clicks. Use presence-based location targeting, ad scheduling for your opening hours and call assets for mobile users. Very small areas have fewer searches, so keep keyword lists focused on buying intent.
