Are Google Ads worth it for a small business? An honest answer

Ask around and you will hear both extremes: the plumber who fills his diary from Google Ads, and the café owner who spent £800 and got nothing. Both are telling the truth. Google Ads is not good or bad in itself. It is a machine that does exactly what your setup tells it to, and most small business setups quietly tell it to waste money.

Here is how to work out, honestly, whether it is worth it for you, and what has to be in place before you spend a pound.

The maths that decides everything

Before budget, before keywords, one number matters: what is a new customer worth? If an average job is worth £300 and one in four enquiries books, an enquiry is worth about £75. If Google can bring you enquiries at £30 each, ads are worth it at almost any budget. If your average sale is £40 and enquiries cost £25, the maths never works, and no amount of clever bidding changes that.

Do this sum with your real numbers before you start. It takes ten minutes and it is the difference between an investment and a gamble.

When Google Ads works well for a small business

• People search for what you sell with intent to buy: emergency repairs, local services, bookings, quotes, specific products.
• Each customer is worth enough to cover the cost of winning them, with room left over.
• You can answer enquiries quickly. A lead answered in five minutes converts; the same lead answered tomorrow goes to a competitor.
• Your website makes it obvious how to buy, book or call. Ads cannot rescue a page that confuses people.

When it usually does not

• Very low-value one-off sales where the click costs nearly as much as the profit.
• Products nobody searches for yet, where demand has to be created rather than captured.
• Accounts set up once and left. Broad keywords plus no attention equals paying for irrelevant searches, indefinitely.

The three things that make it worth it

1. Tracking that records every enquiry

If you cannot see which searches produced phone calls, form fills and bookings, you are guessing. Worse, Google is guessing too, because its bidding learns from whatever you tell it a conversion is. Set up call tracking, form tracking and any checkout or booking events before spending anything serious.

2. Attention every single week

Small accounts do not need hours of work. They need somebody to read the search terms report, block the searches that will never buy, shift budget towards what is converting, and notice when Google introduces a change that affects the account. Thirty focused minutes a week beats a five-hour overhaul twice a year.

3. A budget you can leave alone for 90 days

The first month teaches Google who your customer is. Judging results in week two is like judging a new employee on their first morning. Plan a budget you can commit for a quarter, expect the first month to be the worst, and decide after ninety days of clean data.

What it actually costs

For most local and specialist services in the UK, clicks run roughly £1 to £5, and a realistic starting budget is £20 to £50 a day. Highly competitive trades cost more. The bigger hidden cost historically has not been the clicks, it has been the agency: typically £400 to £1,500 a month to manage an account spending less than the retainer.

That is the part that has genuinely changed. Software can now read the account daily, flag the wasted spend, propose the fixes and apply them once you approve them, which is exactly the routine work a retainer used to pay for. Running Google Ads in house stopped meaning becoming an expert; it means approving good suggestions.

So, are they worth it?

If your customers search for what you sell, a customer is worth more than the cost of winning one, and the account gets weekly attention with proper tracking, yes, firmly. It is one of the few channels where a small business can compete with a big one on equal terms, because the ad auction does not care about the size of your company, only the quality of your setup.

If any of those three are missing, fix that first. AdKing was built for exactly this gap: it sets up the tracking, builds the campaigns, and keeps checking the account every day so the weekly attention happens even when you are busy doing the actual work.
