You’ve decided PPC is worth investing in. Maybe you’ve tried it yourself and burned through budget with little to show for it. Maybe a competitor is running ads everywhere and you want in. Either way, you’re now in the market for a PPC management agency in London and quickly realising there are hundreds of them.
They all say the same things. “Certified Google Partners.” “Proven ROI.” “Transparent reporting.” So how do you actually tell them apart before you sign a contract and hand over your ad spend?
This guide will walk you through the questions worth asking, the red flags worth spotting, and what genuinely good PPC management looks like in practice.
Why Getting This Wrong Is Expensive
A bad SEO agency wastes your time. A bad PPC agency wastes your money daily, in real time.
If your campaigns are mismanaged, you’re not just missing out on leads. You’re actively paying for clicks that will never convert. Poor keyword targeting, weak ad copy, badly structured campaigns, and unmonitored spending can drain thousands from your budget in weeks with nothing to show for it.
The stakes are higher with paid search than almost any other marketing channel, which is why choosing carefully matters so much.
Agency vs. Freelancer vs. In-House: What’s Right for Your Business?
Before you start comparing agencies, it’s worth deciding whether an agency is even the right model for you.
A freelancer can be a cost-effective option for small businesses with tight budgets and simple campaigns say, one or two Google Ads campaigns targeting a local area. The risk is bandwidth and accountability. A solo operator juggling ten clients may not be monitoring your account daily when something needs attention.
In-house makes sense once PPC is a significant, consistent part of your revenue engine and you’re spending enough to justify a full-time salary. Most businesses aren’t there yet.
A PPC management agency is the right fit for businesses that want professional-level strategy, ongoing optimisation, and a team that stays across platform changes without the overhead of hiring internally. Agencies also tend to have multi-platform expertise (Google Ads, Meta, LinkedIn, Shopping), which matters as soon as you want to scale beyond search.
For most growing businesses in London, an agency is the most sensible starting point.
7 Questions to Ask Before Signing Any PPC Contract
1. Who will actually be managing my account?
Many agencies sell you on the senior team, then hand your account to a junior who’s managing thirty others simultaneously. Ask directly: who is the day-to-day account manager, how many accounts do they run, and will you have a named point of contact?
2. How do you structure campaigns, and why?
A competent agency should be able to explain their account structure in plain terms how they organise ad groups, how they approach match types, how they handle negative keywords. If the answer is vague or heavy on jargon without substance, that’s a warning sign.
3. What does success look like, and how do you measure it?
Push past “impressions” and “click-through rate.” The only metrics that matter for most businesses are cost per lead, cost per acquisition, and return on ad spend. Any agency worth hiring should be focused on these from day one.
4. How often will I hear from you?
Monthly reporting is the minimum. But what happens in between? Will they flag issues proactively, or will you have to chase? Get a clear expectation of communication cadence before you commit.
5. Do you have experience in my industry?
Not essential, but valuable. An agency that’s run campaigns for businesses similar to yours will already understand the competitive landscape, typical CPCs, and what messaging tends to work. Ask to see relevant case studies.
6. What access will I have to my own accounts?
Your Google Ads account should belong to you, not the agency. Some agencies manage campaigns from their own account and don’t give you direct access which means if you ever leave, you lose all your campaign history, conversion data, and audience lists. Insist on having owner-level access to your own account from the start.
7. What’s the minimum contract term?
There’s a reasonable answer to this question (three to six months enough time to build momentum and generate meaningful data), and a bad answer (twelve months with no performance clauses). Be wary of lengthy lock-ins with no exit conditions tied to performance.
Red Flags to Walk Away From
Guaranteed results. No agency can guarantee a specific cost per click, conversion rate, or ranking. Google Ads is an auction with too many variables. Promises of guaranteed results are either naive or deliberately misleading.
No transparency on spend. You should always know exactly how much of your budget is going to ad spend versus management fees. Some agencies mark up ad spend without disclosing it. Ask for a clear breakdown.
Vanity metric reporting. If your monthly report is full of impressions, reach, and “engagement” without any reference to leads, sales, or revenue something is being hidden. Good reporting starts with the business outcome, not the platform metric.
They can’t explain what they’ve changed. Every month, your agency should be making changes to the account: testing new ad copy, refining audiences, adjusting bids, cutting underperforming keywords. If they can’t articulate what they did and why, your account may be running on autopilot.
Pressure to start immediately. A legitimate agency will want to understand your business before launching anything. If they’re pushing you to start campaigns before doing any discovery, they’re not building strategy they’re billing you.
What Good PPC Reporting Actually Looks Like
Good PPC reporting tells a story. It doesn’t just show what happened it explains why, and what’s being done about it.
At a minimum, expect to see:
- Total spend vs. budget are you on track, underspent, or overspent, and why?
- Conversions and cost per conversion broken down by campaign and, where possible, by keyword
- Quality Score trends an indicator of how well your ads align with search intent
- Search term reports what people actually typed before clicking your ad, which feeds into ongoing negative keyword management
- Month-on-month comparison so you can see whether performance is improving, not just what last month looked like in isolation
Any agency that can’t give you this level of visibility is either poorly equipped or not doing the work.
Does Being London-Based Actually Matter?
Honestly less than many London agencies would like you to believe.
PPC management is almost entirely remote work. The platforms are online, the reporting is shared digitally, and strategy calls happen on video. There’s no meaningful advantage to an agency being physically based in London for the work itself.
Where location can matter is in understanding your market. A London-based agency may have a sharper intuition for London-specific competitive dynamics, local search behaviour, and what your customers expect. If you’re running campaigns that are heavily local a service business targeting specific boroughs, for example that contextual knowledge has some value.
But don’t pay a London premium for proximity alone. Judge on track record, transparency, and fit.
