Most small businesses running Google Ads have the same problem: the account gets set up, the budget starts spending, and then nobody really looks at it again. That is where an admanager — whether human or AI — is supposed to step in. The role exists precisely because Google Ads does not optimise itself, and the gap between a managed account and an unmanaged one tends to show up fast in wasted spend.
An admanager handles the ongoing decisions inside a Google Ads account — bid adjustments, budget reallocation, pausing underperforming keywords, and reporting — so that performance improves continuously rather than drifting.
What an AdManager Does Inside a Google Ads Account
The term admanager gets used loosely. Sometimes it refers to a person, sometimes to a set of automated rules, and increasingly to AI agents that take over the management function entirely. But whatever form it takes, the core job is the same: make decisions inside the account on a regular cadence.
A good admanager is not just watching dashboards. It is acting on what the data shows — raising bids on keywords that convert, cutting spend on ones that do not, and making sure the daily budget is distributed across campaigns in proportion to where the returns are strongest. These are not one-off tasks. They need to happen weekly at minimum, and in competitive categories, more often than that.
From nine years running a marketing agency, the accounts that performed consistently well had one thing in common: someone or something was making incremental decisions on a tight loop. The accounts that underperformed were usually the ones where management happened quarterly, or only when the client noticed something looked wrong.
Google's own Smart Campaigns automate some of this, but they operate as a black box. You cede control of what actually happens inside the account, which makes it hard to learn, troubleshoot, or scale intentionally.
That tension between automation and control sits at the centre of every admanager decision an SME has to make.
The Difference Between Passive and Active Ad Management
Passive ad management means the account runs on the settings it was built with. Bids stay where they were set. Budgets distribute evenly. Keywords that have never produced a conversion keep spending. This describes a significant proportion of SME Google Ads accounts in practice.
Active ad management means someone — or an AI agent — is reviewing performance data and making changes based on what it shows. This includes negative keyword additions when irrelevant search terms appear, bid increases when a keyword hits a strong conversion rate, and pausing ad groups that consistently drain budget without result.
The distinction matters because Google Ads charges you regardless. The question is whether your admanager is earning back more than it costs through better decisions, or whether the account is simply running on autopilot while the budget depletes. For context on what active management typically costs versus what passive accounts lose, see our article on ad cost on Google and what SMEs actually pay.
| Management Type | Who Makes Decisions | Frequency | Typical Cost Structure |
|---|---|---|---|
| No management | Nobody | Never | £0 management fee, high waste |
| Manual (in-house) | Business owner | Ad hoc | Staff time, inconsistent |
| Agency | Account manager | Weekly/monthly | 10–20% of spend or fixed fee |
| AI agent | Automated AI | Daily | Fixed monthly fee, no % of spend |
How AdManager Functions Map to Real Account Tasks
When someone describes an admanager's responsibilities, it can sound abstract. In practice it breaks down into a specific set of recurring tasks that any experienced account manager would recognise.
Bid management is the most frequent task. Keyword bids need to move in response to quality score changes, competitor activity, and conversion data. Leaving bids static for weeks in an active auction means you are likely overpaying for some clicks and missing volume on others.
Budget reallocation matters as much as bid management, especially across multiple campaigns. If one campaign is producing conversions at £12 each and another at £60 each, a capable admanager shifts budget toward the first. This sounds obvious, but it requires someone to actually look at the data and act on it.
Pausing underperformers is where a lot of budget gets saved. Keywords and ad groups that have accumulated spend without generating leads or sales should be paused, not left running out of inertia. In our agency years, pausing underperformers was consistently one of the highest-ROI actions we could take in an account — it costs nothing and immediately improves efficiency.
Reporting and summaries close the loop. Without a clear report, the business owner has no visibility into what changed, why, and what the account is doing next. A good admanager does not just make changes — it communicates them.
For a deeper look at how these functions translate to paid search more broadly, what a paid search service actually does is worth reading alongside this.
Why SMEs Struggle to Manage Ads Without Dedicated Support
The core problem for small businesses is time, not capability. Running a Google Ads account well requires consistent attention that most business owners simply cannot give it while also running their business. The account ends up competing for attention with everything else, and it usually loses.
Hiring an agency solves the attention problem but introduces a cost structure that can be difficult to justify at lower spend levels. An agency taking 15% of a £2,000 monthly budget earns £300 — which may not be enough to fund the senior attention the account actually needs. The economics often push SME accounts toward junior management or templated approaches.
This is why the admanager function is increasingly being handled by AI agents rather than people. An AI agent can monitor an account daily, act on performance signals immediately, and produce clear summaries — without the overhead structure of an agency or the attention constraints of a business owner.
Overtime is an AI agent built specifically for this function. It logs into Google Ads accounts directly, adjusts bids based on performance data, pauses keywords and ad groups that are not working, reallocates budget across campaigns, and sends plain-language summaries of what it has done and why. The management loop runs continuously rather than waiting for a human to find time.
What Good AdManager Reporting Looks Like
Reporting is often treated as an afterthought, but it is actually one of the most important functions an admanager performs. A business owner does not need to see every data point — they need to know what changed, what it cost, and whether performance is moving in the right direction.
Good admanager summaries include the changes made during the period, the reasoning behind those changes, the current conversion rate and cost per acquisition, and what the account is likely to do next. Bad summaries are either raw data exports with no interpretation, or so high-level they tell you nothing actionable.
One thing worth noting from agency experience: clients who received clear, specific weekly summaries stayed longer and asked better questions. The reporting itself built trust in the management process, which is a practical argument for taking it seriously.
For SMEs thinking about how to evaluate their current admanager situation, it is worth comparing what you are receiving in reports against what active management should actually produce. Our guide on what a Google Ads expert actually does sets out those expectations clearly.
Choosing the Right AdManager Approach for Your Budget
The right admanager approach depends on spend level, internal capacity, and how much control the business wants to retain. There is no single correct answer, but there are clearer and less clear fits depending on the situation.
At spend levels below £1,500 per month, agency management is rarely cost-effective. The percentage-of-spend model does not generate enough revenue for the agency to dedicate meaningful time, and fixed-fee structures at that level often reflect that. An AI agent makes more sense — the management quality is consistent regardless of spend volume, and the cost does not scale proportionally with what you are putting into the account.
At higher spend levels, the choice becomes more nuanced. Some businesses benefit from human strategic input alongside automated execution. Others find that an AI agent handles the full management function adequately and frees up budget that would otherwise go to management fees. See the detailed breakdown of PPC services and what SMEs actually get to understand where the real value sits.
For businesses already spending on Google Ads in 2026, the key question is not whether to use an admanager — it is whether the one you have is actually doing the job. If you cannot point to specific bid changes, paused keywords, and budget moves made in the last two weeks, the management loop is not running properly.
Review what active Google Ads management should cost before making a final decision on structure.
Overtime handles the full admanager function for SMEs — daily bid adjustments, underperformer pausing, budget reallocation, and plain-English summaries — at a fixed monthly cost with no percentage of spend. If your current admanager approach involves waiting until something goes wrong before anyone looks at the account, see how Overtime's pricing compares.
The practical next step is to audit what your account has actually done in the last 30 days: how many bid changes were made, how many keywords were paused, and what your reporting told you about why. If the answer is not clear, your admanager — in whatever form it takes — is not functioning as it should.

Frequently Asked Questions
What is an admanager in Google Ads?
An admanager is anyone or anything responsible for the ongoing decisions inside a Google Ads account — including bid adjustments, budget allocation, pausing underperforming keywords, and producing performance reports. The role can be filled by a human account manager, an agency, or an AI agent.
How often should an admanager make changes to a Google Ads account?
In most active accounts, meaningful changes should happen at least weekly. Bid adjustments and negative keyword additions may need to happen more frequently in competitive categories. Accounts that go weeks without changes are typically underperforming relative to what active management could achieve.
What does an AI admanager do differently from a human one?
An AI agent can monitor account performance daily and act on it immediately, without the scheduling constraints of a human manager. It also applies decisions consistently rather than varying based on who is available. The trade-off is that complex strategic decisions — entering a new market, restructuring campaign architecture — still benefit from human input.
Should an SME use an agency or an AI agent as their admanager?
For most SMEs spending under £3,000 per month on Google Ads, an AI agent offers more consistent management at a lower cost than an agency. Agencies add value at higher spend levels where strategic input and relationship management justify the fee. The key is whether the management function — whatever form it takes — is actually running on a regular cadence.
Can an admanager access my Google Ads account directly?
Yes. Both human managers and AI agents like Overtime are granted access to Google Ads accounts through Google's standard manager account system. The agent or manager can then make changes, pull reports, and adjust settings within the permissions that have been granted — without the business owner needing to be involved in day-to-day decisions.
