TLDR;
- Forget 'local is best'. The best Google Ads partner for your Canterbury business is the one with proven, relevant case studies in your niche, even if they're based in London or Manchester. Proximity doesn't equal results.
- Don't get swayed by a slick sales pitch. You need to grill them on the specifics of Google Ads strategy, conversion tracking, and how they'd approach your specific business goals. If they can't answer technical questions, run.
- Most businesses have no idea what they can actually afford to pay for a lead. Use our interactive LTV to CAC calculator inside to figure out your real numbers before you spend a single pound. This is the metric that matters.
- The mark of a true expert is their willingness to give away value upfront. Look for partners who offer a proper, in-depth strategy session or account audit for free, not just a generic quote. That's how you get a taste of their expertise.
- This guide includes a simple flowchart for vetting case studies and a red flag/green flag checklist for your discovery calls, helping you cut through the noise and find a partner who will actually deliver.
Finding a genuinely good Google Ads partner in Canterbury can feel like a nightmare. You're probably swamped with local agencies that claim to do everything – web design, SEO, social media, and oh yeah, Google Ads. The problem is, they're often a jack of all trades and a master of absolutely none. They can set up a basic campaign, sure, but they lack the deep, specialised knowledge to make it truly profitable, especially in a competitive market.
The biggest myth holding Canterbury businesses back is the idea that you need a local partner you can meet for a coffee. Tbh, you don't need a coffee buddy; you need an expert who can make your phone ring with new customers. Expertise is not defined by a postcode. A specialist in London with a track record of getting results for businesses just like yours is infinitely more valuable than a local generalist who's learning on your dime. This guide is about how to tell the difference and make a choice that actually grows your business, not just your ad spend.
So, how do I spot a real expert from their case studies?
Case studies are the first and most important hurdle. But most people look at them all wrong. They see a big revenue number and get excited, without actually digging into whether it's relevant. A flashy case study for a national e-commerce brand means nothing if you're a local solicitor in Canterbury trying to get more conveyancing leads.
You need to look for relevance above all else. Have they worked with other local service businesses? Do they understand the difference between targeting tourists looking for the Cathedral and residents in postcodes like CT1 or CT2? For instance, one campaign we worked on for a home cleaning company achieved a cost per lead of just £5 by tightly targeting local postcodes. In contrast, a campaign for an HVAC client in a more competitive city sees leads around $60. An expert partner should be able to discuss these kinds of real-world results and explain why they vary. A good case study should clearly outline the initial problem, the strategy they implemented, and the specific results – not just revenue, but cost per lead (CPL), conversion rate, and return on ad spend (ROAS). If their case studies are vague or don't seem to match your business type, that's a massive red flag. They should give you confidence they've solved your exact problem before.
I've seen so many businesses get burned because they were impressed by irrelevant results. To help you avoid this, here's a simple way to think through any case study they show you.
Is the case study from a similar industry/business model?
Relevant!
Are the results (CPL, ROAS) clearly stated and realistic for my business?
Irrelevant.
Potentially a good fit. Dig deeper.
Vague numbers. Be very wary.
This simple process forces you to be critical. If an agency can't show you a single example of success with a business like yours, they're asking you to pay for their education. Don't do it. Any competent agency should have a portfolio of work, and if you need more specific proof, you can learn more about the process of vetting paid ad agencies as a UK business to ensure you're making the right choice.
How much should I actually be spending on ads in Canterbury?
This is the million-dollar question, isn't it? Or rather, the million-pound question. The answer isn't a number I can just give you. The answer comes from *your* numbers. The most common mistake businesses make is setting an arbitrary ad budget without knowing what a customer is actually worth to them. They're flying blind, and they usually crash.
To stop burning cash, you need to ignore vanity metrics like clicks and impressions and focus on two things: Lifetime Value (LTV) and Customer Acquisition Cost (CAC). Your LTV is the total profit you'll make from an average customer over their entire relationship with you. Your CAC is what you spend to get that customer. A healthy business aims for an LTV:CAC ratio of at least 3:1. This means for every £1 you spend on acquiring a customer, you get at least £3 back in profit.
Once you know your LTV, you can work backwards to figure out what you can afford to pay for a lead. Let's say your LTV is £5,000. With a 3:1 ratio, you can afford a CAC of around £1,667. If your sales team closes 1 in 5 qualified leads, you can afford to pay up to £333 for each of those leads. Suddenly, a £50 cost per lead from Google Ads doesn't look so scary, does it? It looks like a bargain.
This is the maths that unlocks intelligent, scalable growth. Stop guessing and start calculating. Use the tool below to get a rough idea of your own numbers.
What tough questions should I ask on the discovery call?
Right, so you've reviewed their case studies and they look relevant. You've done your numbers and you know what you can afford. Now it's time for the call. This is where you separate the real experts from the smooth-talking salespeople who just read a blog post about Google Ads last week. You need to ask specific, slightly technical questions that force them to demonstrate their actual knowledge.
Don't just ask "What results can you get me?". Anyone can promise you the world. Tbh, in paid ads, you can't really promise anything as performance is impossible to predict perfectly. A good partner will be honest about this and talk about a process of testing and optimisation, not guarantees. Instead, ask questions that reveal their process and strategic thinking. Here are a few to get you started:
- "Based on what you know about my business, what initial campaign structure would you propose for us here in Canterbury?" A good answer will involve different campaign types (e.g., Search, Performance Max, maybe Display for remarketing) and discuss segmenting by service and maybe even geography (e.g., targeting locals vs. tourists differently). A bad answer is vague, like "We'll start with a search campaign and see how it goes."
- "How do you approach keyword research and negative keywords?" They should talk about understanding user intent, not just search volume. They should have a clear process for building a negative keyword list to weed out irrelevant traffic (e.g., people searching for jobs, DIY tutorials, or cheap alternatives). If they don't mention negative keywords, it's a huge red flag.
- "What's your process for setting up and verifying conversion tracking?" This is absolutley critical. If you can't track leads or sales accurately, you're just guessing. They should talk confidently about using Google Tag Manager, setting up specific conversion actions (form submissions, phone calls, etc.), and testing to make sure everything is firing correctly. If they fumble this question, end the call.
- "How do you handle reporting and what metrics do you focus on?" The answer shouldn't be "clicks and impressions." They should focus on business outcomes: number of leads, cost per lead, conversion rate, and ROAS. They should be able to explain how they'll communicate performance to you in a clear, understandable way, not just send you a data dump from Google.
Their answers will tell you everything you need to know. You're looking for confidence, clarity, and a focus on a strategic process tailored to *your* business, not a one-size-fits-all template.
"We guarantee a #1 ranking on Google."
No one can guarantee this. They're either lying or confusing paid ads with SEO."We have a secret formula."
There are no secrets, only best practices, rigorous testing, and hard work."We focus on getting you more clicks."
Clicks don't pay the bills. Leads and sales do. This is a classic vanity metric.Vague answers to technical questions.
If they can't explain conversion tracking, they can't do it properly."Let's talk about your business goals first."
They start with strategy and understanding your business, not just tactics."Our process involves constant testing and optimisation."
This shows they understand that Google Ads is an iterative process, not 'set and forget'."We'll focus on CPL and ROAS."
They're focused on the metrics that actually impact your bottom line.They ask you lots of challenging questions.
A true partner will probe to understand your sales process, margins, and customers.Should I hire locally or look further afield to London?
This is the crux of the issue for many Canterbury business owners. There's a natural inclination to want someone local, someone who 'gets' the area. And while a bit of local knowledge can be helpful, it's massively overrated when it comes to Google Ads. The platform's targeting capabilities are so sophisticated that an expert in London can target users in the Canterbury city centre with more precision than a local amateur ever could.
The real question isn't "where are they based?" but "are they a specialist in what I do?". If you run a dental practice in Canterbury, would you rather hire a local agency that does marketing for pubs and retailers, or a specialist dental marketing agency based in Manchester that has scaled 50 other dental practices? The answer is obvious. The specialist understands your customers, your compliance issues, your terminology, and what makes your audience tick. They'll write better ad copy, choose better keywords, and build more effective landing pages from day one.
Often, the deepest pools of specialist talent are in major hubs like London. The agencies there are often exposed to bigger budgets, more complex challenges, and fiercely competitive markets. This sharpens their skills in a way that agencies in smaller cities sometimes can't match. It doesn't mean a Canterbury agency can't be good, but you shouldn't limit your search. By opening up to remote partners, you're not just looking for the best agency in Canterbury; you're looking for the best agency for you in the entire country. In today's world, that's a huge advantage. If you are considering this route, it's worth understanding the specifics of vetting a specialist London Google Ads agency to make an informed decision.
What does a good Google Ads setup even look like?
To make this less abstract, let's imagine a hypothetical Canterbury business: "Canterbury Historic Walks," a premium tour company offering small-group guided tours. They want to attract both tourists already in the city and people planning their trips from London and the South East.
A lazy agency would lump everything into one campaign. A proper expert would build a structure that reflects the different types of customers and their intentions. It might look something like this:
- Goal: Capture active searchers.
- Targeting: People in London & SE searching for...
- "guided tours of canterbury"
- "canterbury cathedral tours"
- "best things to do in canterbury"
- Ad Type: Text Ads focused on unique selling points (small groups, expert guides).
- Goal: Attract tourists already in the area.
- Targeting: Performance Max campaign targeting people physically within a 10-mile radius of Canterbury who show tourist behaviour.
- Ad Type: Mix of images, videos, and text across Google Maps, Display, and YouTube. Ads focus on "Book a tour for today!"
- Goal: Re-engage interested visitors.
- Targeting: People who visited the booking page but didn't complete a purchase in the last 30 days.
- Ad Type: Display Ads with compelling images of the tours and a small discount offer ("10% off your booking").
This structure is smart because it doesn't treat all customers the same. It allocates budget more effectively, speaks to each audience with a relevant message, and ultimately drives a much better return than a simple, lazy setup. This is the kind of strategic thinking you should be looking for from a potential partner. It's not about just 'doing Google Ads'; it's about building a machine that reliably brings in the right customers for your business.
So, what's the verdict?
Choosing a Google Ads partner is a big decision for your Canterbury business. Getting it right can unlock serious growth; getting it wrong can be a very expensive mistake. The key takeaway should be to prioritise demonstrated expertise and a relevant track record over geographical proximity. A partner's ability to drive measurable results for a business just like yours is what you're paying for, not their ability to find a parking space on the High Street.
You need to do your homework. Dig into their case studies, arm yourself with your own business metrics like LTV, and go into discovery calls ready to ask tough, specific questions. Don't be afraid to challenge them and push for details. A true expert will welcome the scrutiny because it's a chance to showcase their knowledge. A salesperson will get defensive or change the subject.
I've detailed my main recommendations for you below as a final checklist.
| Action Item | Why It Matters |
|---|---|
| 1. Prioritise Relevant Case Studies | Ignore geography. Find a partner who has proven results in your specific niche (e.g., local services, B2B, e-commerce). This is the single best predictor of future success. |
| 2. Calculate Your LTV and Affordable CAC | Don't start advertising without knowing your numbers. This calculation will define your budget and success metrics, turning guesswork into a data-driven strategy. |
| 3. Prepare Tough, Technical Questions | Move beyond "what's your price?". Ask about campaign structure, conversion tracking, and negative keywords to separate true experts from salespeople. |
| 4. Insist on a Strategy-First Approach | A good partner will want to deeply understand your business goals, sales process, and customers before they even mention building a campaign. Strategy precedes tactics, always. |
| 5. Look for a Free, High-Value Audit or Strategy Session | The best partners prove their value upfront. A detailed, personalized review of your situation is a huge green flag and shows they're confident in their ability to help. |
