Are Google Ads Worth It for Small Businesses?

Quick answer

Google Ads can be worthwhile for a small business when relevant customers are searching for what it sells, the cost of acquiring a customer leaves enough profit, and the budget supports a meaningful test. Search ads offer pay-per-click billing and flexible budgets, but neither guarantees a return. In my experience, the answer depends on your business economics, competition and how effectively the account is set up and managed.

One of the most common questions I’m asked is whether Google Ads are “worth it”, particularly for small businesses. If I had a dollar, and all that.

It’s a fair question. Nobody enjoys spending money on marketing that doesn’t bring in enough business to justify the expense.

Unfortunately, the answer is a bit “how long is a piece of string?”

There’s plenty of messaging from Google itself - funnily enough - and from agencies suggesting that Google Ads can work for just about any business.

My experience, over more than a decade and across hundreds of accounts, is that it isn’t always the case.

For some small businesses, Google Ads is a cornerstone of their marketing. For others, the numbers are difficult to make work, even with a sensible setup.

Why is Google Ads appealing to small businesses?

Before going further, I’m going to focus mainly on Google Search ads: the ads that can appear when somebody searches for something relevant to your business.

Google Ads now covers much more than the old “AdWords” search platform, including YouTube and Display advertising. Those offer additional opportunities, but they work differently. Search is where many of the small businesses I speak to start.

You pay when somebody clicks

With pay-per-click Search advertising, you pay when somebody clicks your ad. Having it appear without receiving a click doesn’t incur a click charge.

That’s an appealing proposition compared with buying a newspaper placement or radio spot, where you’re paying for exposure regardless of whether anybody responds.

However, a click is still only a visit. You can pay for somebody to arrive at your website and leave without buying or enquiring.

Paying per click makes the cost easier to connect to website traffic. It doesn’t automatically make that traffic valuable … but there is distinct appeal in the concept of only paying per click (not to mention, if you are savvy, it can be possible to leverage this for some heavily discounted branding effect)

You have considerable control over the budget

You can start with a comparatively small budget, adjust it and pause campaigns when required. You don’t have to commit to the sort of upfront placement package you might encounter with traditional advertising.

One detail to understand is that an average daily budget isn’t necessarily a hard daily spending cap. For most campaigns, Google can charge up to twice that amount on a particular day, subject to a monthly limit generally based on 30.4 times an unchanged average daily budget.

That flexibility is useful for small businesses, giving you a clear “pathway” to dip your toes in without going overboard.

But being able to spend a small amount and having enough budget to achieve something useful are two different things.

What determines whether Google Ads is worth it?

The main questions I’d ask are:

• What are you selling, and are people searching for it?

• What does a relevant click cost? (nb there’s only one way to find out … running ads)

• How many visitors become enquiries or customers?

• How much profit does a new customer contribute?

• How much can you afford to spend testing the approach?

These questions matter more than whether Google Ads works for somebody else’s business.

A plumber, an online clothing retailer and a specialist consultant could all get enquiries or sales from Google Ads while having completely different economics.

A small budget can be too small for the market

I’ve been approached by business owners wanting to spend around $5 per day in industries where a single click might cost $5 or more.

At those figures, you’re buying roughly one click per day on average, assuming the budget spends and the click cost holds.

That doesn’t give you much traffic to work with. If you need several enquiries each week, the expectations and budget probably aren’t aligned.

It isn’t impossible for a small number of clicks to produce a valuable customer. But I wouldn’t recommend building a plan around getting lucky, and it may take a long time to gather enough evidence to assess performance.

In some circumstances, I’d consider a tightly targeted local Meta campaign to build awareness instead (as your $5, for example, would likely yield you many times more impressions/eyeballs on your brand)

That serves a different purpose from capturing an active search, and it still needs testing. It isn’t an automatic solution to having a limited budget … but if your budget is very small you might not be best placed to leverage Google Ads.

Ecommerce can be harder than it looks

For an online shop, the relationship between click costs, conversion rate and profit margin can be unforgiving.

Here’s a hypothetical example:

• Your average click costs $2.

• Two per cent of visitors buy.

• That means 50 clicks, costing $100, to generate one order on average.

• If the order contributes $30 after product and other variable costs, before advertising, you’ve spent $100 to acquire $30 of contribution.

Those numbers don’t work on the initial purchase, even before management costs (if you are paying a 3rd party e.g. Google Ads agency)

Repeat purchases may change the picture. A customer who returns regularly could justify an acquisition cost that looks unattractive against their first order.

But I’d want evidence of those repeat purchases and their profitability. “Customer lifetime value” shouldn’t become a convenient excuse for losing money indefinitely.

High-intent searches can be extremely valuable

On the other hand, Search ads can be an excellent way to reach people who already need what you sell.

If you unblock drains in Christchurch, somebody searching “blocked drain Christchurch” is a fairly obvious prospective customer.

You’re reaching them at the point they’re looking for help. For that kind of immediate demand, Google Search is about as good a fit as it gets.

Whether it’s profitable still depends on click costs, enquiry quality, how many jobs you win and what those jobs are worth. But the connection between the search and the service is strong.

Setup and management can make ALL the difference

Sometimes Google Ads isn’t worthwhile because the underlying economics are difficult.

Other times, an otherwise viable opportunity is being undermined by the account strategy, setup or management.

There are plenty of potential pitfalls: irrelevant search terms, unsuitable targeting, wasted placements, unhelpful conversion tracking and ads sending people to pages that don’t answer their needs.

Competition also affects what you pay, and you don’t control how aggressively other businesses bid.

This means two businesses offering similar services can have very different experiences with the platform.

A good setup won’t rescue every business model. But correcting avoidable waste can sometimes be the difference between profitable and unprofitable advertising.

When assessing the return, include setup and management fees as well as the money paid to Google. Your business has to cover the whole cost.

So, are Google Ads worth it for YOUR small business?

I think it’s worth considering when there’s clear search demand, enough profit in a new customer and a realistic budget for testing.

I’d be more cautious when the budget buys very little relevant traffic, margins are thin or nobody has established what an enquiry or sale is actually worth (unless your approach is simply to allocate some budget to test the waters and make further decisions from there)

If you’re already advertising and the results are disappointing, I’d want to establish why before deciding whether to spend more or stop.

Is the account wasting money? Is the website failing to convert suitable visitors? Or are the likely acquisition costs simply too high for the business?

Those lead to different decisions.

My independent Google Ads audits are designed to help with that assessment. Sometimes the recommendation is to improve the account. Sometimes it’s to adjust expectations or consider a different use of the budget.
