Google Ads can feel like the magic button: switch on some ads, and your website gets flooded with new clients.
The reality is more nuanced. For some businesses, Google Ads is a game-changer - qualified leads arrive almost instantly, enquiries climb, and the ROI more than justifies the spend. For others, Ads feel like pouring money into a black hole.
So how do you know if it’s worth it for your business? Let’s break down what Google Ads actually is, why it can work so well for service businesses, and the signs to look for before you spend a penny.
A quick refresher: what Google Ads actually is
Google Ads (formerly AdWords) is a pay-per-click (PPC) platform. You write short text ads that show up when someone searches for a keyword you’ve chosen.
If someone clicks your ad, you pay… whether or not they become a client.
That means two things are critical:
- Choosing the right keywords so you’re targeting people who are genuinely looking for your service.
- Having a website that converts once they land on it.
If you get those right, Ads can work. If you get them wrong, it’s wasted spend.
Why Google Ads can be powerful for services
The biggest advantage is intent.
When someone types “online fitness coach” , or “car insurance quote” into Google, they aren’t casually browsing. They’re looking to spend money in the very near future. Ads give you the ability to appear in that exact moment, right at the top of the page.
Compare that to social media ads: you can target people by demographics and interests, but they may not be in a buying mindset at all. You’re interrupting their scroll.
With Google Ads, you’re showing up for people who are already searching for what you offer. That’s why, if done well, Google Ads traffic is often more qualified and more likely to convert into leads.
Another benefit is speed. SEO takes months (sometimes years) to build up enough authority to rank. Ads give you visibility instantly. That makes them useful for:
- New businesses that need leads while SEO ramps up.
- Seasonal services (tax accountants, wedding photographers, holiday rentals) who need visibility at peak times.
- Testing offers quickly, before investing in long-term SEO content.
But… Google Ads aren’t worth it for everyone
The flip side is that ROI isn’t guaranteed. You’ll see those impressive “$8 return for every $1 spent” statistics, but those are estimates of averages by Google (see how they calculated that here). Some industries and businesses do far better, some do far worse.
The deciding factor comes down to whether you can turn those paid clicks into paying clients. You need to take into account:
- Your margins and customer lifetime value.
- The demand for your service.
- The cost per click in your industry.
- Whether your website can persuade someone to take action.
How to gauge if your service is a good fit
This is really important, and if you want to run a successful campaign, you have to do this work. To find out if Google Ads is worth it for you, ask yourself:
1. Are people actively searching for what I do?
Google Ads only works if people are typing your service into the search bar. If you offer something new or unusual that people don’t know to search for yet, Ads won’t help. In that case, you’d need to create demand through content or social media instead.
👉 Action: Check that the keyphrase you want to target is getting decent search volume.
There are a few free tools out there, but they’re usually limited to a very small number of searches per day or month.
Google’s Keyword Planner is free and unlimited, but you need to sign up for a Google Ads account first (Google makes you jump through a lot of hoops to do this, but here’s a step-by-step guide: https://ahrefs.com/blog/google-keyword-planner/)
You can also use a paid tool like Keysearch, which I’d highly recommend - it’s affordable and great for all kinds of keyword research, not just for ad research.
2. How competitive is my industry?
Google Ads is essentially an auction: a highly competitive industry or keyword means you pay more per click. Research suggests that if you’re in law, insurance or finance, clicks are usually very expensive (imagine £40 per click!).
In these industries, the lifetime value of a single client is very high, and businesses have a lot more budget for advertising, so they drive up the auction price of keywords.
In less competitive industries, you might be paying £2-£3 per click.
👉 Action: Use Google Keyword Planner or a tool like Keysearch to look up the average CPC (cost per click) for your main keywords.
Set a daily budget you’d be prepared to spend on ads, and divide it by that number to see how many clicks you’d realistically get each day (your ad will automatically be switched off once you’ve reached your budget).
Then ask yourself: “Would that be enough to generate leads, given my website’s conversion rate?”

3. How much is one client worth to me?
If your average client is worth £500 or more, you can afford to spend £50–£100 to acquire them. If your service is a one-off at £50, Ads will almost never add up unless your conversion rate is sky-high.
👉 Action: Calculate the value of a single client. Then work backwards to see how much you can afford to spend per lead and still stay profitable.
4. Can my website convert strangers?
This is the biggie (and it’s what I’ve been writing about in The Website Lab newsletter for the last couple of years!)
Before you even think about spending money on Ads, you need to make sure your website positions you as the most credible business in your industry, AND that it’s set up and structured to guide visitors toward getting in touch.
👉 Action: Read my guide on how to make your website more inbound-friendly. Work through each point until you’re satisfied that your website is capable of turning clicks into clients.
5. Do I have time (or help) to manage campaigns?
Google Ads is not “set and forget.” It needs monitoring, keyword adjustments, and ad copy testing. Without that, you’ll pay for lots of unqualified clicks.
👉 Action: Be realistic. Do you have the time and patience to learn? Or the budget to hire an expert?
Local vs online services
The way you use Ads will also depend on whether you serve a local area or work remotely.
Local businesses: You can use geo-targeting to only show ads to people in your area. You don’t want to pay for clicks from 200 miles away.
If you’re eligible, Google’s Local Services Ads (LSAs) can be a simpler option - you pay per lead, not per click. Here’s a breakdown of the differences between Google Ads and Local Services Ads.
Remote/online businesses: You have a bigger audience, but also more competition. Ads can work, but it’s easier if you get niche - e.g. “business coach for architects” instead of just “business coach.”
Readiness checklist
Before you spend a penny, run through this:
✅ I know my numbers (customer value, margins, max cost per lead).
✅ There’s search demand for my service (I’ve checked).
✅ I know my conversion rate, and my website can convert strangers into clients.
✅ My budget matches the cost per click for keywords in my industry.
✅ I (or someone I hire) can manage campaigns and track conversions.
✅ I know what success looks like (specific goals and KPIs).
If you can tick these off, Ads are worth testing.
If not, focus on driving traffic via organic search or social media first.
How Google Ads compare to other channels
| Google Ads (PPC) | Search engine optimisation | Social ads (Instagram, Facebook etc) |
|---|---|---|
| ✅Fast ✅ Measurable ✅ Intent-driven ⚠️ Can get expensive | ✅ Free ✅ Long-term traffic ✅ Compounds over time ⚠️ Slow to get started | ✅ Cheaper clicks than Google Ads ✅ Great for awareness ⚠️ Lower buying intent |
If you have the budget and bandwidth, the smartest approach is a mix: Ads for quick wins and testing, SEO for long-term, and social for awareness.
Is Google Ads worth it for you?
Google Ads isn’t magic. It’s a lever. Pull it when the basics are in place - demand, website, budget, and time to manage.
If those pieces are missing, Ads will just drain your budget.
If they’re in place, Ads could be the fastest way to bring in qualified traffic and get your service in front of the people who are already searching for what you offer.
