A consultant typically costs less and offers more direct, personal attention, but has limited bandwidth and fewer specialist skills on tap (like dedicated landing page design or analytics). An agency costs more but brings a full team — strategist, ad specialist, designer, developer — and can scale with you as your account grows. The right choice depends mostly on your account's complexity and how much you need beyond bid and campaign management alone, and getting this decision wrong tends to show up either as wasted budget on capability you don't need, or as a ceiling on results because capability you do need isn't available.
Consultant model
An independent consultant usually manages a smaller roster of clients personally, offering direct access and a consistent point of contact — when you email them, you're talking to the person actually managing your account, not an account manager relaying instructions to someone else. This suits simpler accounts that mainly need solid, hands-on campaign management without extensive supporting work like custom landing pages or deep analytics builds. The tradeoff is capacity: a good consultant can only manage so many accounts well before quality starts slipping, and if they're unavailable (on leave, overloaded, or simply moved on), there's no backup covering your account in the interim.
Agency model
An agency brings a broader team — typically a dedicated account strategist plus specialists in creative, landing pages, tracking, and analytics — which suits businesses with more complex needs or bigger budgets where those extra capabilities directly improve results. This structure also provides continuity: if your account manager is away, someone else on the team generally has visibility into your account and can step in. The tradeoff is that you're usually one client among many, and the depth of personal attention can vary considerably depending on the agency's size and how your account fits into their client mix.
Skills and resources
Consultants are often highly skilled specifically in campaign management but may need to outsource or skip complementary work like conversion rate optimisation or custom tracking setups — if your landing pages are underperforming or your conversion tracking is unreliable, a consultant focused purely on the ads platform may not be positioned to fix that without bringing in someone else. Agencies generally have these skills in-house, which can mean a more joined-up strategy overall, since the person optimising your ad copy and the person building your landing page are working from the same shared view of what's actually converting.
Cost
Consultants are typically less expensive, since you're paying for one person's time rather than a team — for a straightforward account, this can be a genuinely efficient way to get quality management without paying for capability you don't need. Agencies cost more but that premium often reflects genuinely broader capability, not just overhead — worth judging case by case rather than assuming either option is automatically better value. The right test isn't "which is cheaper" but "which capability set matches what my account actually needs to improve" — paying agency rates for work a consultant could do just as well is as much a mistake as underpaying for work that genuinely needs a team.
Strategy
Both models can deliver strong strategy, but agencies are generally better positioned for more complex, multi-channel strategies (Google Ads working alongside a broader sales funnel or marketing automation setup), since they have the additional expertise on hand to coordinate across channels rather than optimising Google Ads in isolation from everything else happening in the funnel. A skilled solo consultant can still deliver excellent single-channel strategy; the difference tends to show up specifically when the ads account needs to work in concert with landing pages, email follow-up, and CRM data that sit outside the ads platform itself.
Tracking and landing pages
This is often where the real performance difference shows up — an agency with in-house landing page and tracking expertise can iterate on the parts of the funnel outside the ad platform itself, which a standalone consultant typically can't offer without bringing in outside help. In practice, we've seen accounts where the ads themselves were well-managed but conversion tracking was broken or attribution was unreliable, meaning every optimisation decision downstream was being made on flawed data — fixing that requires technical capability that goes beyond the ads platform, and it's exactly the kind of gap an in-house specialist team is built to close.
Scalability
If your account and budget are likely to grow significantly, an agency generally scales more smoothly, since additional specialists can be brought in without a full relationship change — your point of contact might stay the same even as more capability gets added behind the scenes. A solo consultant has a natural ceiling on how much complexity they can manage well, and hitting that ceiling usually means either a decline in quality of attention or an eventual, disruptive switch to a different provider right as your account is growing and can least afford instability.
Accountability
Both models should offer clear reporting and accountability, but it's worth asking directly: what happens if performance dips, who's responsible for catching and fixing it, and how quickly do you get a response. This matters more than the consultant-vs-agency label itself — we've seen agencies with sluggish response times and consultants who catch and address issues within hours, and the reverse. Ask for a specific example of a time performance dipped and how it was handled, rather than accepting a general assurance about "proactive management."
A hybrid path worth considering
Some businesses land on a middle path: a consultant for day-to-day campaign management, supplemented by a specialist brought in specifically for a landing page rebuild or a tracking overhaul as a one-off project. This can work well if the consultant is comfortable coordinating with outside specialists and the scope of that outside work is genuinely bounded — it becomes harder to manage cleanly if the account needs ongoing specialist input across multiple areas at once, at which point an agency's built-in coordination usually becomes the simpler option.
Which option suits which business?
Smaller accounts with straightforward goals often do well with a skilled consultant — if your needs are essentially "manage my campaigns well and keep costs efficient," a consultant can deliver that at a lower cost than an agency team. Businesses with larger budgets, more complex funnels, or ambitions to scale quickly tend to get more value from an agency's broader capability, particularly once landing page performance, tracking accuracy, or multi-channel coordination start mattering as much as the campaigns themselves. Neither model is inherently superior — the right call comes down to an honest read of how complex your actual needs are today, and realistically, over the next twelve months, since switching providers mid-growth is disruptive in its own right. For a sense of realistic monthly costs either way, see our guide on Google Ads management costs in Australia, and for how much of the day-to-day work is genuinely automatable regardless of who manages it, read Google Ads automation: what to automate.
Making the switch later
It's worth knowing upfront that moving from a consultant to an agency (or the reverse) later is entirely normal as a business's needs change, though it's rarely instant — expect a handover period where the new provider gets across your account history, past testing, and what's already been tried. Choosing well the first time reduces how often you need to go through that transition, which is another reason it's worth being honest about where your account is likely to be in a year, not just where it is today, when making the initial decision.
FAQs
Should I hire a Google Ads consultant or agency? Choose a consultant for simpler accounts needing hands-on campaign management; choose an agency if you need broader capability like landing page design, tracking builds, or plan to scale significantly.
Is an agency more expensive than a freelancer? Generally yes, but the premium often reflects a broader team and skillset — whether that's worth it depends on how much of that extra capability your account actually needs right now versus later.
When should I outsource Google Ads? When managing it internally is taking time away from higher-value work, or when campaign performance isn't improving despite consistent effort — either signals it's worth bringing in dedicated expertise rather than continuing to manage it as a side task.
