The biggest problem in Google Ads is not the cost per click or the competition. It is not knowing whether what you are paying for is actually working. Most advertisers receive monthly reports with dozens of metrics, a few upward-trending graphs, and the general sense that something is happening. But without knowing what to look for and what to ask, it is nearly impossible to distinguish an agency genuinely driving results from one managing your budget without real accountability for outcomes. If you haven’t hired an agency yet, the guide on how to choose a Google Ads agency in Australia will help you avoid the most common mistakes from the start.
The first signal: if your agency leads with clicks, CTR, and impressions
Vanity metrics are the first symptom of a misdirected account. A report that opens with “this month we achieved 48,000 impressions and a CTR of 4.1%” is measuring activity, not results. Impressions and clicks are the cost, not the return.
The metrics that matter for a service business are: leads generated, cost per lead, and, if conversion tracking is properly set up, cost per acquired client. For eCommerce, they are: sales, revenue generated, ROAS, and cost per order. If your agency does not centre its reporting on these metrics, or if the answer becomes evasive when you ask about them directly, there is a structural problem with how the account is oriented.
An agency doing its job properly knows that its continued engagement depends on client results, not on the client believing something is happening. When reports consistently focus on metrics the agency controls (impressions, CTR, ad position) rather than metrics the business cares about (leads, sales, revenue), the priorities are misaligned.
The second signal: conversion tracking setup
Conversion tracking is the technical foundation of any well-run Google Ads account. Without it, Smart Bidding operates blindly and cannot optimise toward the outcomes that matter. Without it, you also cannot know what is actually working.
A clear warning sign is an account that has been running for months where conversion tracking is absent, incomplete, or misconfigured. A “conversion” should represent a real business action: a form submitted, a phone call placed, a purchase completed. Not a visit to the homepage or a 50% scroll event.
Another common symptom: the tracking is configured, but conversions are inflated. Multiple conversions are being counted per user (the same form submitted twice), or low-value actions are being counted as conversions (visiting the contact page without submitting the form). If the conversion count Google reports does not match the actual leads landing in your inbox or CRM, the tracking is wrong, and the algorithm is optimising toward the wrong signal.
The third signal: which search terms are triggering your ads
The search terms report, available in any Google Ads account, shows exactly what people were searching when they saw and clicked your ads. It is the most revealing report for detecting poorly managed accounts.
Ask your agency for the search terms report from the last 30 days. If you see entirely irrelevant searches consuming budget (“electrician apprenticeship,” “plumber salary,” “how to fix my own pipes” for a plumbing services company, for example), there is a serious issue with match type configuration and negative keyword management.
A well-managed account has an active negative keyword list under regular review. Spend on irrelevant search terms should be marginal, below 5% of total budget. If it is higher, you are paying for traffic that will never convert. This connects directly to the question of what Google Ads management should actually cost and whether the management fee is justified by the quality of the work.
The fourth signal: what has changed in the account in the last 30 days
An actively managed account has a change history. Google Ads stores a complete record of every modification: new keywords added, bid adjustments, ad copy changes, new negative keywords, budget modifications. Ask for the change history from the last 30 days.
If the history is empty or near-empty (only automated bid adjustments made by the algorithm), the account is not being actively managed. Professional Google Ads management means weekly review of search terms, negative keyword refinement, ad copy testing, bid strategy assessment, device and schedule analysis, and landing page feedback. An account nobody touches for weeks loses performance progressively as market conditions shift.
Questions a good agency should answer without hesitation
There are four questions any agency doing its job properly should answer clearly and without preparation:
How many leads (or sales) did we generate last month and what did each one cost? If they do not have the figure ready or the answer is vague, the problem is either in tracking or in results orientation.
What campaign structure are we using and why? A clear explanation of why you are using Search rather than Performance Max, or vice versa, and what the rationale is for the targeting approach.
What were the three main changes made this month and what was the reasoning? An actively managed account always has a concrete answer to this.
Can you give me read-only access to the account? An agency that refuses to give the account owner read-only access has something to hide. Read-only access allows no changes, only visibility. If they will not grant it, that is a significant red flag.
What a transparent agency relationship looks like
A legitimate agency relationship is one where the client understands what the account is doing, why, and what the results are, in plain language rather than just dashboards. Monthly reporting should include: total spend, leads or sales generated, cost per result, what changed, and what is being tested next.
Good agencies proactively surface problems. If something is not working, they raise it before you ask. If a campaign type is not delivering, like Performance Max in a lead generation context, they recommend the change rather than continuing to bill management fees while the budget runs without results.
