How Much Should You Spend on Ads?

Short answer: it depends.
Longer answer: it depends, but not in the way most people think.

Ad spend isn’t about picking a magic number. It’s about understanding what you’re trying to achieve, what a customer is worth, and whether your foundations are strong enough to support paid traffic.

Start with the goal, not the budget

Before deciding how much to spend, be clear on what ads are meant to do. Are you trying to generate leads, make sales, launch something new, or simply test demand? Different goals require different levels of spend. A vague goal leads to vague results.

Know what a customer is worth

This is the part most businesses skip and is super important. If you don’t know roughly what a customer is worth over time, it’s impossible to judge whether ads are working. Spending $1,000 to make $2,500 is very different from spending $1,000 to make $1,100. Ads only make sense when they’re tied to real revenue.

What kind of business do you have? What’s the average value of a spend? If you’re not going to get strong returns on ad spend, it might be better to put your effort into other marketing.

Start smaller and learn

Ads are not an all in gamble. They’re a testing tool. Starting with a smaller, controlled budget allows you to see what resonates, what converts, and what doesn’t. Early spend is about learning, not scaling.

Your website matters more than your spend

If your website is unclear, slow, or confusing, increasing ad spend won’t fix it. Ads amplify whatever experience people land on. A strong website and clear messaging often have more impact than a bigger budget.

Consistency beats bursts

Spending a small amount consistently often works better than short, heavy bursts. It gives platforms time to optimise and gives you better data to make decisions. Erratic spending usually leads to erratic results.

There is no universal percentage

You’ll often hear rules like “spend 5–10% of revenue on ads.” These can be useful benchmarks, but they’re not laws. A new business may need to spend more to gain traction. An established one may spend less because demand already exists.

Ads should earn the right to grow

The goal isn’t to spend more. It’s to spend profitably. Once ads are producing consistent, positive returns, increasing spend makes sense. Until then, restraint is a feature, not a failure.

The short version

Set a clear goal. Know what a customer is worth. Start small. Fix your foundations. Spend consistently. Scale what works.

That’s how ad budgets stop feeling like guesswork and start feeling like a tool.
