Choosing the right Google Ads consultant comes down to three things: relevant experience, transparent communication, and a genuine interest in your results rather than just your retainer. A good consultant will ask about your business before they talk about their services. They want to understand your margins, your audience, and what a good lead or sale is actually worth to you.
If you want to see how Digital Womble approaches ongoing paid-search work, review the Google Ads Management service. If you would rather begin with an independent account diagnosis before committing to management, the Google Ads Account Review is the more focused starting point.
What a Good Google Ads Consultant Actually Looks Like
Google-certified consultants hold a Google Ads certification, which confirms they have passed a technical assessment set by Google. That certification is a basic quality filter, not a guarantee of brilliance, but it tells you the person knows the platform. Beyond certification, look for someone who can explain what they plan to do in plain English, without hiding behind terms like impression share or modified broad match without explaining what those mean for your budget.
For a marketing manager like Tom in Manchester who is under pressure to show pipeline results, finding a consultant who speaks in outcomes rather than activity metrics matters enormously. You need someone who will tell you how many leads the campaign produced last month, not just how many clicks it received. A consultant who conflates activity with results is one to avoid.
As John Russell, Director at Digital Womble, puts it: “Most Google Ads accounts I audit haemorrhage cash on search terms the business owner has never even looked at. That's not a technology problem - it's an attention problem. My job is to care about your budget as much as you do, and apply the kind of scrutiny that only comes by thinking it's my money.”
That scrutiny should show up in measurable account decisions. You can review anonymised examples on the Google Ads results page, including CPC, CPA, CTR and conversion-efficiency changes from specific client periods.
Red Flags to Watch Out For
Google's negative-keyword guidance reinforces the principle: paid-search optimisation is about excluding irrelevant intent as well as finding demand. Judge changes on query relevance, conversion quality and commercial outcome—not clicks in isolation.
The first red flag is any consultant who guarantees a specific return before they have seen your account. No one can promise a 5x return on ad spend without knowing your industry, your competitors, your margins, and your current conversion rates. If a consultant leads with a bold guarantee, that is a sales tactic, not a credible assessment.
Lock-in contracts with no performance clauses are another warning sign. A good consultant is confident enough in their work to offer a reasonable notice period, typically one to three months, rather than tying you into a twelve-month agreement with no exit. Be wary of anyone who insists on retaining admin access to your Google Ads account, too. Your account should always remain in your name. If a consultant owns the account, you lose your data and your campaign history the moment you stop working together.
Vague reporting is a third problem area. If a consultant sends you a monthly PDF full of charts but cannot tell you which campaigns drove actual revenue, something is wrong. You should always be able to see what you are spending, what clicks cost, and what those clicks turned into. If that information is not forthcoming, ask for it directly. If they cannot provide it clearly, walk away.
The Questions Worth Asking Before You Sign Anything
Before you commit to working with anyone, ask them directly: who will actually be managing my account day to day? Some agencies sell you on a senior consultant but hand your account to a junior team member once the contract is signed. Knowing who is doing the work and how much experience they have is a fair question and a reasonable expectation.
Ask how they handle campaigns that are not performing. Any honest consultant will tell you that not every campaign works first time. What matters is how quickly they identify the problem, how they communicate it to you, and what they do to fix it. A consultant who never admits a campaign is underperforming is one who is not being straight with you.
Also ask what access you will have to your account and your data throughout the engagement. You should have owner-level access to your Google Ads account at all times. Ask whether they use Google Analytics, Google Tag Manager, or any other tracking tools, and whether those will be set up under your own properties. If you decide to part ways, you want to walk away with all your data intact.

How to Check Their Track Record Without Taking Their Word for It
Testimonials on a consultant's own website tell you the story they want you to hear. That is not necessarily dishonest, but it is curated. For a more balanced picture, ask for two or three client references you can contact directly, not just written quotes. A confident consultant will have no problem providing those.
Look at their Google Business Profile, Trustpilot listing, or recommendations from past clients. Check whether those clients are in industries similar to yours. A consultant who has only ever worked with fashion retailers may not have the same instincts for a B2B manufacturing campaign in the North West. Sector experience is not everything, but it shortens the learning curve considerably.
Case studies are more useful than testimonials because they show context. A well-written case study will tell you the starting point, what the consultant changed, and what happened to performance as a result. If the case studies are vague or heavy on jargon, that often reflects the way the consultant actually works. Ask for specific numbers: cost per lead before and after, return on ad spend, conversion rate improvements. If they cannot share numbers due to confidentiality, ask for percentage improvements instead.

What to Expect Once You Hire Someone
In the first few weeks, a good consultant will spend time auditing your existing campaigns or setting up tracking correctly before spending a penny on ads. Rushing to launch without understanding your baseline is a common mistake, and an experienced consultant will resist the temptation to jump in too fast. This is especially true if you have an existing account with historical data worth learning from.
Expect a period of testing and optimisation before campaigns hit their stride. Google Ads does not produce instant results in most cases. The algorithm needs conversion data to optimise bidding effectively, and that takes time to accumulate. Be cautious of anyone who promises transformational results in week one.
Once campaigns are running, you should receive regular reporting, whether weekly or monthly depending on your budget and complexity. Good reporting includes what was tested, what worked, what did not, and what the plan is next.

Making Your Final Decision
Once you have spoken to two or three consultants, compared their approaches, and checked their references, the decision often comes down to trust. Do they communicate clearly? Do they answer your questions directly? Do they treat your budget with the same care they would treat their own? Those are soft signals, but they matter as much as any certification or case study.
For marketing managers running campaigns for SMEs, the right consultant is one who fits the scale of the business. You do not necessarily need a large agency with dozens of account managers if your monthly ad spend is £2,000. A freelance specialist or a small focused team may actually give you more attention and better results at that budget level.
Read the contract carefully before signing. Check what happens to your account access if you cancel, how disputes are handled, and whether there is a minimum notice period. These are not awkward questions to ask. Any consultant worth hiring will have clear answers to all of them. For a full picture of what different consultants charge and how pricing structures work, see Google Ads management services pricing.
If you are not ready to commit to ongoing management, starting with a structured Google Ads Account Review gives you a defined diagnosis of wasted spend, search terms, tracking, targeting and landing-page issues before you decide what should happen next.
