How to choose a PPC advertising agency without getting burned
A practical filter for evaluating PPC agencies before you hand over your ad account. The questions most business owners skip are the ones that matter most.
Most PPC agency pitches follow the same script.
The agency shows you a portfolio, names a few platforms they manage, tells you about their reporting cadence, and describes a vague process that involves regular optimization. If you have been through one of these before, you know the issue: every agency says the same things, so the pitch does not tell you who is actually any good.
The problem is not that agencies lie. Most of them believe what they are saying. The problem is that the standard interview rewards confidence and presentation, and those two things do not predict whether someone can actually protect your budget.
Here is a more useful framework.
Start with the tracking audit, not the strategy pitch
Before any agency talks about campaigns, keywords, audiences, or creative, ask them this:
What is the first thing you inspect in a new account before you change anything?
A weak answer is some version of "we review the account and look for opportunities." That is a non-answer. Opportunities to do what, exactly?
A stronger answer will mention conversion tracking. Specifically: whether the conversion events the account is optimizing toward actually reflect real business outcomes, or whether they are measuring something softer, like a page view, a session, or a soft form fill that does not qualify.
The reason this matters: Google Ads and Meta Ads both optimize bidding toward whatever conversion event you tell them to optimize toward. If that event is wrong, the algorithm spends budget efficiently toward the wrong outcome. The account looks clean in reports and the business bleeds money.
An agency that does not check this first is either inexperienced or planning to show you impressive numbers that do not translate to your pipeline.
Ask what they would cut before they scaled anything
The second useful question:
What would you cut in our current setup before you touched bids or budgets?
This question forces the agency to show you where their attention actually goes.
| Answer type | What it tells you |
|---|---|
| "We would optimize the campaigns" | No clear framework for waste |
| "We would look at the search terms first" | They know where budget leaks in Google Ads |
| "We would audit conversion events, then search terms, then audience overlap" | They sequence correctly |
You want the agency to name specific waste categories. In Google Ads, common ones include low-intent search terms entering through broad or phrase match, duplicate keywords across campaigns bidding against each other, branded searches being overbid, and campaigns that look efficient in platform reports but produce leads the sales team will not call.
In Meta Ads, common waste categories include audience overlap between ad sets (the algorithm bidding against itself), creative fatigue that has not been refreshed, and optimizing toward a soft event like add-to-cart or a landing page view instead of purchase or lead.
An agency that can describe these categories without prompting has seen them before and knows how to find them in your account.
Check their incentive structure
Most agencies charge one of two ways: a flat monthly fee or a percentage of ad spend.
The percentage model creates a misalignment. An agency charging 10 to 15 percent of spend earns more when your budget grows. Their incentive is to scale your spend, not to make it more efficient.
A flat fee does not have that problem. The agency earns the same whether you spend $5,000 per month or $50,000 per month, so their interest stays with the efficiency of your budget rather than its size.
This is not a hard rule. There are excellent agencies on percentage models and bad ones on flat fees. But it is worth asking directly, and worth noticing whether the first thing they recommend after onboarding is to scale budget before fixing the account structure.
Ask for the first week, not the ninety-day plan
Ninety-day plans are easy to write and impossible to evaluate before you hire someone. First weeks are harder to fake.
Ask:
What would your first five working days look like if we started on Monday?
A useful answer is specific enough that you can picture the actual work.
| Strong first week | Weak first week |
|---|---|
| Pull 90 days of spend and qualified outcomes from the account | "Learn your business" |
| Audit every conversion event before touching bids | "Optimize campaigns" |
| Pull the search term report for wasted spend | "Build a strategy" |
| Map existing audiences for overlap | "Send recommendations" |
| Produce a cut, fix, and test list | "Get aligned with your team" |
The agency does not need to know your business deeply before doing this work. They need to know how ad platforms work, where money leaks, and what the first forensic pass looks like. If they cannot describe that without prompting, you are probably hiring someone who will spend your first month running campaigns instead of inspecting them.
Ask how they report a bad month
Good months are easy to present. Anyone can send a screenshot of a ROAS that went up. Bad months separate operators from vendors.
Ask:
How would you report a month where performance dropped?
You are listening for structure. A useful bad-month report describes what changed, what caused it, what they are cutting, what they are testing next, and what decision they need from you. It is action-oriented and honest about what is unclear.
A bad answer is mostly context, platform screenshots, and reassurance that things will improve. That is what agencies send when they are managing the client relationship instead of the account.
Red flags to watch for
A few things that should make you slow down before signing:
They mention impressions or reach in the first meeting without being asked. Impressions are an output metric. If an agency leads with how many people saw your ads, they may not be focused on what those people did next.
They cannot give you a clear answer on what they will own versus what they need from you. Some agencies require significant client involvement to produce creative, copy, or approvals. There is nothing wrong with that, but you should know before you start what the ongoing time commitment looks like on your side.
They promise results before they have seen your account. Every account is different. An agency that promises a specific ROAS or CPL before auditing your current setup is either guessing or telling you what you want to hear.
They do not ask about your sales process. Paid ads drive leads or purchases. If the agency does not ask how leads are handled, whether you have a CRM, what a qualified lead looks like, and what happens after the form fills, they may be optimizing for platform metrics that do not connect to your actual business.
What good management actually looks like
Good PPC management is mostly diagnostic. The agency spends the first month understanding where money is going and why, then building the account structure to redirect that money toward the highest-intent demand. Scaling comes after the structure is sound.
The difference between an agency that helped and one that did not usually comes down to this: did they fix the foundation before they grew the budget, or did they grow the budget first and hope the foundation was solid enough to hold?
Most accounts that come to us have the same pattern: the prior agency added campaigns, expanded audiences, and raised bids. CPL fell briefly, then settled back or rose. The underlying tracking was never verified, the search terms were never properly filtered, and the bidding system was learning from the wrong signals.
Fixing that takes a few weeks of unglamorous work. An agency that is willing to do that work before the growth pitch is usually worth talking to further.
