Google Ads Consultant: What They Do, How They Work and What to Expect
Google Ads consultant: what they do day-to-day, when to hire one over an agency, and how to spot a weak one fast.
In this article
A third of Google Ads spend is wasted on average in accounts without proper optimisation, according to a WordStream analysis of more than 15,000 accounts (2026). That’s not a problem with the channel. It’s a problem with who manages it, or how they manage it.
When an ecommerce business hires a Google Ads consultant, what they expect and what they actually get are often two different things. Some expect a technician who clicks buttons. Others expect someone to fix a quarter’s ROAS in two weeks. Neither matches what a good consultant actually does.
This article explains what a Google Ads consultant does day to day, how working with one differs from working with an agency, how to evaluate whether yours knows their stuff, and what to expect in the first 90 days.
Key Takeaways:
- 29% of Google Ads accounts generate zero conversions in 90 days (WordStream, 2026).
- PPC agencies charge between 10% and 20% of ad spend in management fees (AgencyAnalytics, 2025), with frequent account turnover and limited access to historical data.
- A freelance consultant works inside your own account. If the relationship ends, you keep everything: history, data, audiences.
- The first 90 days of serious management should include a full audit, structural fixes and a first round of tests.
What does a Google Ads consultant actually do day to day?
A third of paid search budget is wasted in unoptimised accounts, which works out to more than £1,000/month on an average account, according to WordStream (2026, 15,000+ accounts). Stopping that waste is, in concrete terms, the main job of a consultant.
But the work isn’t just “optimising campaigns.” In practice, it means reviewing Quality Score and spotting search terms that eat budget without converting (something that comes up in almost every active account, every week). It means calibrating Smart Bidding against actual conversion volume, not against Google’s automatic recommendations, which tend to push higher spend. Then there’s ad copy: writing variants, running them with enough traffic to be statistically valid, and making decisions based on data rather than gut feel. And finally, translating dashboard numbers into business recommendations the client can actually understand and discuss, not once a month in a 30-page PDF, but regularly and in plain language.
A good consultant doesn’t run on autopilot. They work with judgment, and that requires real analysis time, not just panel access.
On accounts I manage with budgets between £3,000 and £15,000/month, I spend between 8 and 15 hours a month on active work in the platform, plus time for analysis, communication and test preparation. Less than that isn’t management. It’s supervision.
Consultant vs agency: the difference that matters most for your account
55% of brands consider it likely they’ll switch their main agency within the next six months, and 53% cite lack of value as the main reason for ending the relationship, according to the annual Setup® survey (2023, 300+ marketing decision-makers). That’s not a budget problem. It’s a structural problem with how many agencies operate.
The interesting thing is that the technical gap between a senior consultant and a good agency specialist is usually small. What changes is the structure around the work.
The first difference is account ownership. Agencies typically operate through their own MCCs. If you leave, the data history, saved audiences and accumulated Quality Score can stay with them. With a consultant who works directly inside your account, all of that is yours from day one. What I lose if we part ways is access. You lose nothing.
The second difference is who actually works on your account. At an agency, the account manager who sold you the service is rarely the person managing your campaigns week to week. There’s turnover, there are juniors, there are accounts split across multiple specialists. With an independent consultant, the same person who analyses your account is the one who explains the results to you, with no one sitting between the problem and the solution.
And the third, which few agencies will admit: incentives. An agency gets paid the same whether results are good or bad. A consultant working without a long-term retainer has a direct incentive to make results justify the continuation.
For a more detailed look at these differences, read when an agency makes sense and when a consultant is the better fit.
| Criteria | Agency | Consultant |
|---|---|---|
| Account ownership | Agency MCC; if you leave, they may keep the history | Your account from day 1; access revocable at any time |
| Who manages your account | Rotating junior; the senior only shows up for the sales meeting | One specialist from start to finish |
| Transparency | White-label dashboard with selected metrics | Direct access to Google Ads and GA4; you see exactly what I see |
| Incentive alignment | Gets paid the same whether results are good or bad | No long-term retainer; results justify the continuation |
| Recommended scale | £20,000+/month, multiple channels, large team | £1,500-£20,000/month, active account, fast decisions |
When does a consultant make more sense than an agency?
PPC agencies charge between 10% and 20% of ad spend in management fees, with fixed retainers ranging from $500 to over $10,000/month depending on account complexity, according to the AgencyAnalytics report (2025). For accounts spending between £1,500 and £10,000/month, that percentage is a significant chunk of the total investment, and it rarely buys direct access to a senior specialist.
A freelance consultant makes sense in several specific situations, though not in all of them.
If your spend is between £1,500 and £20,000/month, a consultant’s fee is competitive with an agency’s, and the level of real attention is typically higher. Above £20,000/month, agency teams start to justify themselves through operational capacity and breadth of service.
If your account is complex and can’t afford mistakes (a poorly structured Shopping setup or Smart Bidding with the wrong thresholds can cost you weeks of ROAS), you can’t afford to have it managed by someone who’s had the account for three weeks and is juggling twelve others.
Direct access is another factor. Some clients need to ask a technical question and get an answer that same day, not wait for the monthly meeting. That doesn’t happen at most agencies, and when it does, it’s not usually the person who makes the decisions.
And if you operate across multiple markets or languages, a trilingual consultant handles campaigns in English, French and Spanish without intermediaries or brief translations that distort the message.
Before hiring anyone, it’s worth going through the most common Google Ads mistakes to know what you might be inheriting if the account has had previous management.
In practice, the inflection point tends to sit around £5,000/month in spend. Below that, many accounts don’t generate enough conversion volume to benefit from continuous active optimisation. Above it, active management starts to have a measurable week-on-week impact on ROAS.
How do you know if a Google Ads consultant is any good?
25% of Google Ads accounts have never added a single negative keyword. Accounts that do use negative keywords convert at 13%, compared to 4.6% for those that don’t: nearly three times higher, according to WordStream (2026, 15,000+ accounts analysed). It sounds obvious, but that 25% figure matches what I consistently see when I audit a new account.
How do you tell a good consultant apart from someone who charges to watch the autopilot run? A few concrete signals:
- They talk about account structure, segmentation and conversion signals before they ask about budget. If the first question is “how much are you spending?”, that’s a red flag.
- They ask for access to GA4 and sales data, not just the Google Ads dashboard. Without that, they’re optimising blind.
- They explain their decisions. They don’t just send vanity metrics in a monthly report.
- They propose specific tests with clear hypotheses: “we’re going to test this copy variant in the highest-spend ad groups because…”
- They don’t promise specific results on short timelines. Anyone promising “+30% ROAS in 30 days” without knowing your account either doesn’t understand how the channel works, or is simply making it up.
The warning signs on the other side are just as clear. Be cautious if the first meeting is a sales pitch, not a diagnostic. Or if they can’t explain which bidding strategy they use or why they chose it, not just “I’m using tROAS” but why that target and not another. Or if they cite number of active campaigns as a measure of work done, which is the most common vanity metric in this industry. And especially if they don’t know what Quality Score is or how it directly affects actual CPC, or if they insist on working through “agency accounts” rather than your own.
What happens in the first 90 days with a consultant?
Accounts with at least one negative keyword convert at nearly three times the rate of those without: 13% vs 4.6% (WordStream, 2026). That kind of structural fix should happen in month one of serious management, not month three.
The first 90 days with a consultant should follow this rhythm.
The first two weeks are for the audit: a full account review covering keywords, segmentation, ad extensions, bidding strategies, tracking and conversion data quality. Without a real diagnosis, any change that follows is just a well-intentioned guess.
Month one is for structural fixes: the highest-impact changes first. Search terms consuming budget without converting, negative keywords that should have been in place months ago, tracking quality, removal of ad groups with no useful volume. These are changes with immediate effect that don’t need months of data to validate.
Month two is when real optimisation begins: bid adjustments based on observed behaviour, the first copy testing cycle, and a review of Smart Bidding strategy with the correct conversion thresholds. When Smart Bidding works and when it costs you money is a question that inevitably comes up at this stage.
By month three, with a clean foundation and tracking working properly, the real strategic work starts: landing page tests, keyword expansion with clear intent, efficiency analysis by product or category. This is where the investment made in the first two months starts to return measurable results.
How I work: direct access, no juniors, no agency accounts
I’ve been managing Google Ads accounts since 2017. I’ve worked with budgets of £500/month and budgets of £25,000/month. One thing becomes clear over that time: the quality of management has less to do with budget size than with who makes the decisions and what information they have to make them.
To start with, I work in your account, not mine. I don’t have an agency MCC full of client accounts. I access your Google Ads account directly, through my own user. If we stop working together tomorrow, I lose access. You keep everything: the history, conversion data, audiences, accumulated Quality Score. That model isn’t the industry standard. It’s a deliberate choice.
There are no intermediaries either. I’m the same person who speaks to you in the first meeting, who manages the account every week and who explains the results at the end of the month. There’s no account manager sitting between the problem and the solution. When there’s an urgent change to make, I make it. I don’t wait for someone to delegate it.
Reporting works the same way: Data Studio connected directly to Google Ads and GA4. You see exactly what’s being spent, what’s converting and what’s being tested, with no vanity metrics and no opacity. What doesn’t work is when both sides operate in silos, with the client watching ROAS on their dashboard and the consultant watching CPC in the platform, and no one connecting the two.
And I’m trilingual as standard: English, French and Spanish. For ecommerce businesses operating across multiple markets, that removes a layer of friction that many agencies handle poorly, or simply don’t handle at all.

Frequently asked questions about Google Ads consultants
How much does a Google Ads consultant charge?
PPC management fees typically range from 10% to 20% of ad spend, with fixed retainers from $500 to over $10,000/month depending on account complexity (AgencyAnalytics, 2025). A senior freelance consultant usually works on a fixed monthly fee based on volume and complexity, without a percentage commission on spend. That removes the conflict of interest of unnecessarily scaling budgets.
How long does it take to see results?
It depends on the account’s starting condition. Structural fixes (negative keywords, ad group reorganisation, bid adjustments) can have an impact within the first few weeks. Strategic improvements take two to three months to accumulate enough data. 29% of Google Ads accounts generate zero conversions in 90 days (WordStream, 2026). That figure drops sharply with active management from day one.
What’s the difference between a Google Partner and someone without certification?
Google Partner certification means the consultant manages a minimum spend volume, meets Google’s performance standards and passes regularly updated certification exams. In practice, it’s a baseline quality filter. It doesn’t guarantee results, but it does indicate that the person knows the platform in depth and works actively on it with real accounts.
Can I hire a consultant if I already have an in-house marketing team?
Yes, and it’s a common combination. The internal team handles content strategy, email and social; the consultant manages the paid channel with specialist technical judgment. The coordination works well when there’s clarity about who makes decisions in each area and there’s easy, shared access to conversion data.
What happens to my data if I end the relationship with the consultant?
If the consultant works inside your own Google Ads account (which is how it should be done), you keep everything when it ends: campaign history, conversion data, audiences, Quality Score, configurations. You just revoke the consultant’s user access. If they work inside an agency account, that data isn’t yours. Worth clarifying before you start, not after.
