How to Choose a PPC Agency (UK Guide)

Want to know the secrets to selecting a PPC agency that will actually increase your profit?

Get it right, and you have a channel that generates measurable, scalable revenue with every pound accounted for.

But if you slip up, you are paying two fees: one to Google and one to the shoddy agency, all while the campaigns tank and you feel left in the dark.

The UK market has no shortage of PPC agencies, but the challenge is finding an agency you can trust.

This guide will help you make that decision clearly before you sign anything, and spot the red flags before it is too late.

What a PPC Agency Actually Does

Pay-per-click advertising involves placing ads in front of people who are actively searching for what you offer and paying only when they click.

A good PPC agency handles keyword research and strategy by identifying which searches your ideal customers are making and which are worth bidding on.

It builds the campaign structure, writes the ad copy, sets up conversion tracking, manages bids, and refines everything based on the data.

It also handles the landing pages built for conversion rather than general browsing, negative keyword lists that stop budget leaking onto irrelevant searches, and audience segmentation that treats different buyer types differently.

Crucially, the most valuable thing a PPC agency brings is the judgement to know what a campaign needs at each stage.

For a clear breakdown of what agencies typically charge for all of this, our companion guide on PPC management costs covers pricing in detail.

Signs of a Great PPC Agency

Successful agencies share a set of characteristics that are worth knowing before you start talking to anyone.

They lead with proof. Case studies with real numbers from named clients in identifiable sectors.

They ask good questions before they quote.

A PPC agency that sends you a proposal without asking about your margins, sales process, average customer value, and your current tracking setup is a red flag.

In marketing, you cannot achieve results based on assumptions. Marketing is a science, not an art.

Additionally, they are clear about what they do.

An agency that claims to excel at every channel, industry, and type of campaign at every budget level is telling you something about how seriously to take their expertise.

They should also give you ownership of everything.

Your Google Ads account, domain, and tracking data must belong to you. If not, please walk away.

Signs of a Bad PPC Agency

Equally worth knowing, and arguably more important.

An agency that guarantees results should be treated with immediate scepticism.

Google Ads operates in a live auction where outcomes are influenced by competitor behaviour, market conditions, and search volume patterns that no agency can fully control.

Anyone promising a specific number of leads or a guaranteed ranking position is either misinformed or being deliberately misleading.

An agency that focuses on click volume and impression share rather than conversions and revenue is measuring the wrong things.

Offering phone support as an "extra" shows low care for their clients.

Really cheap management fees. This generally means the agency has a high turnover of clients and isn't invested in your success.

Clicks are inputs. Sales are outputs.

If your reporting is full of traffic metrics and light on conversion data, the agency may be optimising for the numbers it can control rather than the ones that matter to your business.

Questions to Ask Before You Hire

These are the questions that separate agencies that know what they are doing from those that sound like they do.

Who will manage my account day-to-day?

Some agencies pitch with senior staff and deliver with juniors who are managing twenty accounts simultaneously.

Know who your account manager is and how many other clients they manage.

How do you structure campaigns for a business like mine?

The answer should be specific to your industry, product type, customer journey, and budget level. Anything else is worthless.

What does your reporting look like, and how often do we speak?

You want live data access and a regular conversation.

Can you share examples of results from clients in a similar situation to mine?

You need to see actual campaign data, even anonymised, showing what they achieved and the numbers they spent to get there.

Red Flags to Avoid

Some of these have been touched on above, but they are worth being explicit about.

Vanity metrics in reporting.

Impressions, clicks, and click-through rates tell you something, but they are not the story.

What it really comes down to is how many conversions were generated, at what cost, and what revenue they produced.

An agency that leads with reach and traffic in its reporting draws your attention toward appealing, pleasing numbers rather than results.

Guaranteed results.

Nobody can guarantee what an auction will produce. Confident projections based on data and experience are reasonable. Guarantees are not.

Vague answers about strategy.

If you ask how they would approach your campaigns and the answer is generic, that is the answer you will get in the account, too.

In-House vs Agency: Which Is Right for You?

In-house PPC management makes sense when someone on your team has genuine expertise and enough time to give the account consistent attention.

In that situation, you save on management fees and gain someone deeply familiar with your business. The economics can work well.

But the challenge is finding and hiring this talent.

As well as this, an in-house PPC manager working on a single account has less exposure to what works across different sectors than an agency managing 30 accounts.

They may not have seen the bidding patterns, the keyword dynamics, or the conversion rate issues that an experienced agency has encountered and solved many times over.

In other words, they might not have the mileage an agency has: the deep experience across the board.

For most businesses, the agency model makes more sense, particularly when starting, scaling spend, or when the account requires more hours than an individual can give.

The hybrid model can be the best of both, but it requires clarity around who owns what decisions.

What Good Reporting Looks Like

Good reporting starts with access.

You should be able to log in to a live dashboard at any time and see your spend, conversions, cost per conversion, and return on ad spend.

Here's a screenshot of the dashboard our clients see at CreateTheWeb.

Context is also key.

If the conversion rate dropped last month, why, and what has been changed as a result?

If a new campaign is outperforming expectations, is spend being reallocated to capture more of that opportunity?

It is your money, so do not be afraid to ask questions or be critical.

The numbers that matter most to businesses are how many leads came in, how many turned into customers, and what each one cost to acquire.

Transparent reporting, above all, even when the story is mixed, is the mark of a relationship built for the long term.

How We Work at CreateTheWeb

Every PPC campaign we manage is built in your account. You own it from day one, and you keep everything if you ever decide to move on, for complete peace of mind.

We also build a dedicated landing page with every campaign, including conversion optimisation, consumer psychology, persuasion techniques, and simple design.

In our experience, this single factor has more impact on cost per conversion than almost anything else in the account.

And you get this at no extra cost.

As well as this, clients see live reporting on their own dashboard and speak to us regularly.

But how about our results at CreateTheWeb?

Boatswain Joinery, a one-man joinery business running campaigns on a £300 monthly budget, gets leads at £11.84 each and is now booked through 2026.

Gym Flooring Bristol achieved a click-to-conversion rate of 7.7 per cent, above the industry average, through targeted campaigns and a free dedicated landing page.

This is what happens when the strategy is right, the tracking is accurate, and the campaign is actively managed rather than left to run.

We do not offer guaranteed results, and we do not lock clients into arrangements that protect our revenue at their expense.

But we let our previous and current results do the talking.
