Question
Is Google Ads worth it for a small business?
Google Ads is worth it for a small business when the arithmetic works: the cost of a click in your sector, times the clicks it takes to get an enquiry, has to come in below what an enquiry is worth to you, with the management cost included. For most local services and many small shops it does; for sectors where a click costs more than a tenth of the profit on a sale, it usually does not, and no amount of clever management changes that.

The sum, in four numbers
Take what a customer is worth to you in margin, and the share of enquiries you win; together they give what an enquiry is worth. Take the cost per click for your searches in your area, which Google's Keyword Planner shows for free, and divide it by a realistic conversion rate, around five per cent for a Search ad landing on a page built for the search; that gives the ad spend per enquiry. If the second number, plus a share of the management fee, is comfortably below the first, the ads pay. If it is close, the account has to be run tightly to stay on the right side. If it is above, the ads lose money from the first click.
Where it usually works
- Local services with a phone-call conversion and a job worth a few hundred pounds or more: heating, electrical, roofing, locksmiths, garages, removals.
- Shops with a product feed, where Shopping ads put a picture and a price in the results, and the margin per order covers the click.
- Professional and B2B services where one client is worth thousands, so even an expensive click is cheap against the case.
- Any business with a specific search behind it: people type the job and the town, and the ad answers exactly that.
Where it usually does not
- Low-margin products sold one at a time, where the click costs more than the profit on the sale.
- Businesses that cannot answer the phone or the form in the hours people search, so the click is paid for and the enquiry goes elsewhere.
- A website that takes six seconds to load on a phone and buries the number: the ads pay for the site's faults by the click, and fixing the site comes first.
The five-minute test
Open Keyword Planner, type the five searches a customer would make, set your area, and read the top-of-page bid range. Divide the top of the range by 0.05. If the result is below what an enquiry is worth to you, the ads are worth a three-month test with a tight Search campaign. If it is above, put the money into the Google Business Profile and a few months of SEO first. Either answer is a good outcome; the expensive one is not asking.
What worth it looks like after three months
Not clicks, and not a graph of impressions. A cost per enquiry you can name, a list of which enquiries became customers, and a return against ad spend plus fee that you would repeat.

Follow-up questions
- How much should a small business spend to test Google Ads?
- Enough to buy a few hundred clicks in a month on one service in one area, which for most sectors is a few hundred pounds. Fewer clicks than that cannot be judged.
- Is SEO a better use of the money for a small business?
- Often, if the map pack is winnable and you can wait a few months. The two are not exclusive: the ads tell you which searches convert, and the SEO makes them cheaper.
