Is Google Ads Worth It for a Trades Business? A Straight Answer

The Question Behind the Question

Most owners asking “is Google Ads worth it” aren’t really asking about Google Ads. They’re asking: if I put money into this, will I get more back than I put in? That’s a fair question, and it deserves a real answer rather than “yes, definitely” from someone trying to sell you management.

The honest answer is: it depends entirely on the maths of your specific business, and most of the bad experiences owners have with Google Ads come from nobody doing that maths properly before spending.

The Maths That Actually Matters

Forget cost-per-click in isolation — it tells you almost nothing on its own. What matters is cost-per-lead, and what matters more than that is cost-per-lead against what a converted lead is worth to you.

If your average job is worth £3,000-£10,000+, a lead costing £150-£200 is cheap, even if the individual clicks that produced it cost £20-£50 in a competitive market. If your average job is worth £150, that same cost-per-lead makes no sense at all. The channel isn’t the variable that decides whether Google Ads is “worth it” — your job value is.

When Google Ads Genuinely Isn't Worth It

It’s not the right lever for every trades business, and I’d rather tell you that upfront than take your budget anyway. It’s a poor fit when:

Your average job value is too low to absorb a competitive cost-per-click in your niche. Your booking capacity is already maxed out and you don’t need more leads, just better ones — that’s a qualification problem, not an ads problem. Your website or offer has a conversion problem that ads will just expose faster and more expensively. In any of these cases, the honest move is to fix the underlying issue first, not throw ad spend at it.

How to Judge It Properly Before You Spend

1. Know your job value firstWork out your average job value and margin before you look at a single ad metric. This is the number everything else gets measured against.
2. Set a realistic cost-per-lead ceilingBased on your job value, decide what you could afford to pay per lead and still make good margin — then judge the account against that, not against a generic industry number.
3. Give it enough runwayA brand-new account has no data to learn from. Expect early weeks to be about tracking and manual bid control, not peak efficiency — judging it too early is the most common way owners write off a channel that would have worked.
4. Track to the booked job, not the clickConversion tracking needs to reflect genuine enquiries — phone calls and form submissions that turn into surveys — not clicks or impressions that look good in a report but mean nothing.
