The short answer: Google Ads is worth it for a small NZ business when three things are true: people actively search for what you sell, a new customer is worth noticeably more than the cost of winning one, and your website turns clicks into enquiries. If any of those is missing, fix that first, or ads will mostly burn money.

Here are real numbers from NZ campaigns I’ve run, and how to work out whether ads will pay for you.

Real results from NZ businesses

Pack My Home (removals, Auckland): 214 conversions at a 33.33% conversion rate, $19.08 per lead. Cost per lead dropped from $42.33 after we tightened the suburbs and rebuilt the landing page. They now get over 70 leads a month.
Yin’s Remedial Massage (Nelson): 77 conversions from $584 in ad spend — $7.54 per booking, at a 9.95% conversion rate.
Confinement Escape Rooms (Taupō): 28.55% click-through rate on their brand campaign, about 7 times the typical average, and $6.82 per conversion.
Bubble Cleaning (commercial cleaning): a $10 a day Performance Max campaign bringing in commercial leads at $49.77 each.

Different businesses, different budgets, but the same pattern: tight targeting, a page built to convert, and every enquiry tracked.

Do the maths before you spend a dollar

You need two numbers:

What a customer is worth to you. Not just the first job — the profit over time, including repeat work and referrals.
What a lead is likely to cost. In most NZ local markets, somewhere between $10 and $60 a lead is common, depending on your trade and competition.

If one in three leads becomes a job, a $20 lead means a $60 job cost. If an average job makes you $800 profit, that’s an easy yes. If it makes you $50, it’s a no.

Why Google Ads fails for some businesses

Advertising to the wrong areas. Paying for clicks from suburbs you don’t want to drive to. This was Pack My Home’s biggest waste before we fixed it.
Broad keywords. Showing up for “free”, “DIY”, “jobs” and “how to” searches from people who’ll never pay you.
Sending clicks to the homepage. A page built for one service, with a clear next step, converts far better.
No tracking. If you can’t see which clicks became calls, you can’t cut what isn’t working.
Too small a budget to learn. I usually recommend at least around $500 a month in ad spend so Google has enough data to optimise. Smaller can work in quiet markets.

When Google Ads is the right move

You need work now and can’t wait two or three months for SEO to build.
You’re launching a new service or moving into a new area.
There’s a seasonal rush you want to catch (heat pumps before winter, decks before summer).
Your competitors are getting the top spots and you’re not.

When to hold off

Your website doesn’t work well on a phone, or has no clear way to get in touch.
You’re already booked out and can’t take more work.
Very few people search for what you do. In that case, other channels usually work better.

Ads and SEO work best together

Ads bring calls this week but stop the moment you stop paying. SEO and your Google Business Profile take a couple of months but keep working. Most businesses I work with run ads while SEO builds, then scale ads back once they’re ranking. More on that in local SEO or Google Ads first.

The bottom line

Google Ads is worth it when the maths works and the basics are in place. If you’d like a straight answer for your business, I offer a free look at your market: what people search for, what the leads would likely cost, and whether it’ll pay. See Google Ads for trades
