Is Google Ads worth it for a small business?

It is the one form of advertising that reaches people while they are looking for what you sell, which is a genuine and unusual advantage — social advertising interrupts people who were not thinking about you at all. That difference is why Google Ads can work for a small business when nothing else does. It is also why it is expensive, and why a badly set up account burns a month's budget in a fortnight.

The thing that makes it different

Someone typing "emergency electrician Leeds" has a problem right now and is choosing who to call. You are not persuading them to want something; you are competing to be the one they pick.

That means the intent is already there, so the conversion rate can be far higher than any other channel — and it means everyone else knows this too, so the click costs real money.

The whole question is therefore arithmetic, not opinion: does a click cost less than a click is worth to you?

Work out whether it can possibly pay

Do this before spending anything. Four numbers:

1. What a customer is worth in profit — not revenue, and over a couple of years if they come back.
2. What share of enquiries you win. Be honest.
3. What share of clicks become enquiries. Assume something modest until you have real data.
4. What a click costs in your trade. The platform will estimate it before you spend.

Multiply the middle two to get how many clicks you need per customer, multiply by the cost per click, and compare that to the first number.

Worked through, it is usually stark. If a customer is worth £60 and clicks cost £6, you need better than one enquiry per ten clicks and to win nearly all of them — unlikely. If a customer is worth £2,000, a £6 click is cheap and you should probably have started already.

High-value, considered purchases are where this works. Low-value one-off jobs rarely survive the maths.

The settings that quietly waste the budget

Most small accounts lose most of their money to a handful of defaults.

• Broad match keywords. The default lets Google show your advert for anything it considers related, which is much broader than you expect. Start with phrase and exact match, and widen deliberately.
• No negative keywords. The single biggest saving available. Add "free", "cheap", "jobs", "salary", "DIY", "training", "how to" on day one, then keep adding from the actual search terms report — which is the only report worth opening weekly.
• Location set too wide. Check the targeting option as well as the radius: the default can include people merely interested in your area rather than in it.
• The Display Network left on. Search campaigns can opt you into banner adverts across the web by default. For most small businesses that spends the budget on people who were not searching at all. Turn it off.
• Sending every advert to the homepage. The commonest and most expensive mistake — the page should match the promise.
• No conversion tracking. Without it you are buying clicks and guessing. Track calls and form submissions before you scale anything.

Do the free version first

If you are a local business and your Google Business Profile is half finished, you are about to pay for traffic you could have had. The map results sit above the ordinary ones, cost nothing, and are decided by things you control. Do that first.

Similarly, if you have no reviews, adverts send people to a business that looks unproven. The click is the same price either way; the outcome is not.

When it genuinely works

• Urgent problems. Emergency trades, locksmiths, vehicle recovery. People search, call the first credible option, and do not shop around.
• High-value work where one job pays for months of clicks.
• You can answer immediately. Paid enquiries decay fast; if the phone rings out you are buying leads for whoever answers.
• A specific, unusual service with low competition and clear search demand.
• Filling known gaps — a quiet season, a new area, a service you want more of.

When to leave it alone

• Low-value one-off jobs. The maths rarely works.
• You are already at capacity. Buying work you cannot do well is worse than not buying it.
• Your destination does not convert. Ads amplify what already happens. Fix that first.
• You cannot commit a few hundred pounds to learning. Below a certain spend there is not enough data to improve anything, and you will conclude it does not work when you never tested it.
• You will not look at it weekly for the first month.

A cautious way to start

1. Pick one service you want more of, not everything you do.
2. Tight location, set to presence rather than interest.
3. Phrase and exact match only, a small list of terms you would actually type.
4. A page of negatives before you launch.
5. Display Network off.
6. Send it to a page about that one service, with a price signal and one obvious action.
7. Conversion tracking on for calls and forms.
8. A small daily budget, run for a month rather than a week.
9. Read the search terms report weekly and add negatives. This is the whole job.
10. Judge on cost per enquiry against what a customer is worth.

If after a month cost per enquiry is comfortably below customer value, scale slowly. If it is not, stop — that is a real answer and it saved you the next six months.

About the automated options

Google increasingly pushes campaign types that hand over targeting, placement and creative in exchange for simplicity. They can work, and they make the two things a small business most needs — knowing where the money went, and being able to change one thing — considerably harder.

For a first campaign on a small budget, prefer the version where you can see the search terms and turn things off. Automation is easier to justify once you know what a good result looks like for your business.

The bottom line

It reaches people already looking, which is why it converts and why it costs. Do the arithmetic first: high-value or urgent work usually pays, low-value one-off jobs usually do not. Finish your free Google listing before buying clicks. Then start narrow — one service, tight location, exact and phrase match, negatives written in advance, Display off, a matching landing page and conversion tracking — and judge it on cost per enquiry after a month.
