Question
How much should a Manchester business spend on Google Ads?
Spend enough to buy the clicks that produce an enquiry for less than the enquiry is worth, and enough for the bidding to learn, which for a target cost per action means around thirty conversions a month by Google's own guidance. The number comes from the cost of a click for your searches with Keyword Planner set to Greater Manchester, not from what is left over at the end of the month.

Start from the click, set to Greater Manchester
- Open Keyword Planner inside any Google Ads account and type the five searches a customer would make, in the words they use, not yours.
- Set the location to Greater Manchester, or to the boroughs you actually serve if that is narrower; Bolton and the city centre do not share a bid range.
- Read the top-of-page bid range for each search. It is an estimate, and real clicks land above or below it with Quality Score, but it is your searches in your area, not a national average.
- Divide the top of the range by a realistic conversion rate: around five per cent for a Search ad landing on a page built for the search, corrected with real data after the first month.
- Compare the result with what an enquiry is worth to you: the margin on a job, times the share of enquiries you win.
The floor: enough conversions to learn
Google's own guidance is that a Smart Bidding strategy wants around thirty conversions in a thirty-day window before a target cost per action behaves. Below that the campaign still runs, on manual bids with tight match types, and improvement comes from the person reading the Search Terms report rather than from the algorithm. Work the floor backwards: thirty enquiries at your conversion rate gives the clicks, and the clicks at your CPC gives the spend at which the account starts to teach itself. In a dear Manchester sector, solicitors and cosmetic clinics for instance, that floor can be higher than a small business wants to hear, and better heard before spending than after.
The ceiling: impression share lost to budget
The account tells you when more money would buy more customers. Each Search campaign reports the share of eligible searches it was shown for and why the rest were missed: lost to budget, or lost to rank. Lost to budget, with a cost per enquiry under what an enquiry is worth, is the signal to spend more, and a good monthly report says so with the number. Lost to rank means an extra pound buys nothing until the ads, the page or the Quality Score improve. Raise in steps of twenty to thirty per cent and stop when the cost per enquiry crosses the line from step five above.
A worked sum, hypothetical
| Line | Hypothetical figure |
|---|---|
| Margin on an average job | £300 |
| Enquiries won | One in three, so an enquiry is worth £100 |
| Top-of-page bid from Keyword Planner, Greater Manchester | £2.50 a click |
| Conversion rate guessed at 5% | £50 of ad spend per enquiry |
| Twenty enquiries a month wanted | £1,000 of ad spend, before the management fee |
These are illustrative numbers, not Manchester benchmarks. Put your own in each row and the budget falls out of the last line.
The check in your own account
If you already advertise, add search impression share, lost to budget and lost to rank to the campaign table. An account losing a large share to budget while converting profitably is under-funded; one losing it to rank is under-managed, and more money will not fix that.

Follow-up questions
- Is there a minimum worth starting with?
- Enough to buy a few hundred clicks a month on one service in one part of Greater Manchester. Fewer cannot be judged, and a dear sector needs more clicks than a cheap one to reach a conclusion.
- Should the budget be the same every month?
- Rarely. A Christmas party venue and a boiler engineer have opposite seasons; a fixed budget overpays the quiet months and is capped by noon in the busy ones. Move it with the enquiries, not the calendar.
