How much should you spend on Google Ads?

A useful Google Ads budget starts with the value of a customer, the number of qualified opportunities required and the likely cost of reaching them. For many SMEs, a meaningful initial test begins around £1,000 to £3,000 in monthly media spend.

The short answer.

Many UK SMEs should plan an initial media budget of around £1,000 to £3,000 per month for one focused Google Ads campaign. Competitive sectors, national coverage, ecommerce or several service lines may need £3,000 to £10,000 or more per month to gather useful data and generate a worthwhile volume of opportunities.

A smaller budget can work when the location, service and keywords are tightly controlled. The budget is too low when it spreads spend so thinly that the campaign cannot learn or reach enough qualified searches to judge performance.

Start with enough budget to answer a commercial question, not simply the smallest amount Google will accept.

Work backwards from the result.

Begin with a realistic target for new customers or qualified leads, then estimate the conversion steps required to reach it.

Customer targetHow many new customers would make the campaign commercially worthwhile?
Close rateHow many qualified leads does the business normally need to win one customer?
Lead rateWhat proportion of useful website visits are likely to become enquiries?
Click costWhat does a relevant click typically cost in this market and location?
Learning allowanceHow much room is needed to test search terms, messages, bids and landing pages?

Indicative monthly media budgets.

Under £1,000

Best treated as a narrow test: one service, a limited location and a small group of high-intent searches. It may take longer to produce reliable evidence.

£1,000–£3,000

A common starting range for local and regional SMEs. It can support a focused campaign with enough activity to begin comparing search terms, ads and lead quality.

£3,000–£10,000

Suitable for broader geography, several profitable services, higher click costs or a stronger lead-volume target. The landing experience and tracking become increasingly important.

£10,000+

Often used for competitive national markets, ecommerce, multiple campaigns or organisations with proven conversion economics and the capacity to handle demand.

Media spend is not the whole cost.

  • Setup and research. Account structure, keyword research, exclusions, conversion tracking and campaign planning.
  • Management. Search-term review, bid and budget decisions, testing, reporting and commercial interpretation.
  • Landing pages. Stronger message alignment and conversion journeys can make the same media budget work harder.
  • Creative assets. Display, YouTube, Performance Max and paid social activity may require copy, design or video.
  • Tracking. Reliable calls, forms, sales and lead-quality feedback are essential for sensible optimisation.

Why we recommend a three-month test.

A campaign needs enough time to move beyond launch assumptions. The first month reveals actual search behaviour and tracking issues. The second allows meaningful refinement. The third provides a better view of lead quality, costs and whether the route can scale.

This does not mean leaving poor activity untouched. Search terms, exclusions and obvious problems should be managed from the start, while larger conclusions wait for sufficient evidence.

Budget follows economics

A campaign with a higher cost per lead can still be highly profitable when customers are valuable and close rates are strong. A cheap lead is poor value when it is unlikely to become a customer.

  • Can calls, forms, purchases and lead quality be measured reliably?
  • Is the landing page relevant, credible and easy to act on?
  • Who will respond to leads, and how quickly?
  • What result would justify maintaining or increasing the budget?

Frequently asked questions.

What is a good starting budget for Google Ads?

For many focused SME campaigns, £1,000 to £3,000 per month in media spend can provide a useful starting test. Competitive sectors, broad locations or several services may require more.

Is £500 a month enough for Google Ads?

It can be enough for a tightly focused local test where click costs are modest, but limited budgets produce data slowly and may not support several services or locations.

How long should I test Google Ads?

Three months is a sensible initial test for many businesses. It gives campaigns time to gather search-term, conversion and lead-quality evidence while still allowing controlled decisions.

Are Google Ads management fees included in the media budget?

Usually not. Media spend is paid to Google, while setup, management, landing page and creative fees are paid to the agency or specialist managing the activity.
