One of the trickiest parts of running ads is deciding how much to spend. A useful guide is the 30% rule. This means that your ad spend should be no more than 30% of the sales you expect to generate from the campaign.

Let’s say you’re aiming to bring in £3,000 in sales from your next campaign. Using the 30% rule, your maximum budget should be around £900 (30% of £3,000). That way, you’re not overspending compared to the results you want.
For example:
- A local tree surgeon spending £180 on ads should aim to generate at least £600 worth of contracts from the ad campaign.
- An online fitness coach with a £90 ad budget should look to generate at least £300 on course or membership sales.
Always work backwards from your sales goal. That way, your budget stays realistic and tied directly to results.
