Great report. Flat revenue. Here are the nine signs of a bad PPC agency, what a good one does instead, and how to check each one yourself this week.
Your agency's report looks great. Return on ad spend is up. Cost per lead is down. The charts point the right way.
Revenue hasn't moved.
That gap is the most expensive problem in paid advertising, and it hides well. Bad PPC agencies rarely get fired for a terrible month. They get kept for two more years because nobody inside the company can tell whether the ads are working. If you're the owner, CEO, or marketing lead who has to defend that spend, this guide is for you. You don't need to know how a bid strategy works. You need to know where to look.
Most agencies grade their own homework. They pick the metrics, build the report, and explain the results. When the conversion numbers come straight out of Google Ads or Meta, the platform that takes your money is also the one keeping score.
Here's how that plays out. Picture a typical three-day stretch:
If the campaign is set to optimize toward those 25 conversions, it is literally programmed to find more of the wrong people. The report looks like growth. Your sales team sees nothing.
And because switching is painful, a stalled relationship can run for years. A 2025 ANA and 4As report found media agencies keep a client for 44 months on average. That's almost four years of paying for a gap nobody can see.
None of the red flags below require PPC expertise to spot. Each one comes with what a good agency does instead and a check you can run this week.
Red flag
What it looks like
Every report is clicks, click-through rate, impressions, and "conversions." Ask how many of those became customers and the answer is a shrug, or a promise to look into it.
What a good agency does
Reports connect ad spend to qualified leads, pipeline, and revenue from your CRM. They can tell you your cost per qualified lead, and which campaigns produce the leads that close.
Red flag
What it looks like
Google and Meta learn what a "conversion" is from whatever the agency told them to count. If that's every form fill, the algorithm has no idea which leads became customers, so it optimizes for volume.
What a good agency does
Closed deals flow back from your CRM into the ad platforms through offline conversion imports or enhanced conversions for leads, so bidding learns from the leads that actually turned into revenue.
Red flag
What it looks like
Lead volume is up and your sales team is quietly ignoring a big share of it. Junk form fills, wrong locations, students, and spam all count as wins in the report.
What a good agency does
Lead quality is the target. The agency works with sales to define a qualified lead, excludes the junk, and judges campaigns on cost per qualified lead. We wrote more about this trap in Your Cost Per Lead Is Down. So Why Is Your Pipeline Still Empty?
Red flag
What it looks like
Results flattened out, and the only recommendation is a bigger budget. More spend raises your cost per acquisition, and the answer is still more spend.
What a good agency does
Before asking for more money, a good agency finds the waste in the money you already spend: search terms that never convert, missing negative keywords, landing pages that leak, and audiences that look busy but never buy.
Red flag
What it looks like
The management fee is a percentage of ad spend. When the agency recommends a bigger budget, it is also recommending a raise for itself.
What a good agency does
A flat management fee, kept separate from what you pay Google, Microsoft, or Meta. Their advice on budget is then just advice.
Red flag
What it looks like
The account was created under the agency's login, or you've never had admin access to it. Ask for access and you hear about their "proprietary setup" or "secret sauce."
What a good agency does
The ad accounts, the conversion data, and the history belong to you. Google's own advertiser guide says an agency "must set up a separate Ads account for you," and even when an agency's manager account is linked, your account "still owns its data and has the ability to remove ownership access by unlinking."
Red flag
What it looks like
An impressive strategist ran the pitch. After the contract was signed, your account went to someone you've never met, who is juggling a dozen other accounts. Typos show up in your ads.
What a good agency does
The people who review and plan your account are the people who run it. You know their names, and they can explain every change without checking their notes.
Red flag
What it looks like
Every call walks through the same charts. Nobody says what was tested, what was learned, or what will change next month. You hang up knowing exactly as much as before.
What a good agency does
Each call ends in a decision: what got tested, what the result was, what changes next, and what the agency needs from you. Every change is explained in plain language.
Red flag
What it looks like
The pitch promised guaranteed results, and the contract locks you in for 12 months with a penalty to leave early. Both protect the agency more than they protect you.
What a good agency does
No guarantees. Nobody controls the auction, and we'd be wary of any agency that claims otherwise. A good agency commits to named deliverables, visible work in your own account, and a plan you can keep, then earns the next month. Here's why we don't do long-term contracts.
Flip the red flags over and you get the qualities of a good PPC agency. If you're comparing agencies, or deciding whether to keep the one you have, this is what to look for.
| Quality | What it sounds like | What to ask for |
|---|---|---|
| Revenue-first reporting | "Here's your cost per qualified lead, and here's which campaigns closed business." | A report that ties spend to CRM outcomes |
| Tracking past the form | "Your closed deals feed back into Google, so bidding learns from real customers." | A list of conversion actions and where each one comes from |
| Waste before budget | "Before you spend more, here's what we cut." | The search terms they excluded last month |
| Aligned incentives | "A flat fee. Your budget is your decision." | A fee that stays the same when spend goes up |
| Your accounts, your data | "You're the admin. We're a guest." | Admin access under your own company email |
| Senior people on the work | "I'm the one who made that change, and here's why." | The names of the people making changes |
| A plan you can keep | "Here's what we'd do next, whether or not you hire us." | A written, prioritized plan you keep |
One thing that isn't on the list: a badge. A Google Partner badge is a useful floor, but look at what Google actually requires to earn it: at least $10,000 in managed ad spend over 90 days, half the account strategists certified, and an optimization score of 70% or higher, which largely reflects how many of Google's own recommendations get applied. None of that measures whether your leads turned into revenue.

Get My Second OpinionEvery account has gaps. A single red flag usually means something specific is broken, like a conversion action counting page views, and a good agency will fix it once you point it out. Ask the question and watch how they answer. Defensiveness tells you as much as the answer does.
Three or more red flags is different. It usually means the account has stalled, and the reporting is built in a way that makes the stall hard to see. Plenty of agencies get a company to a certain level and then flatten out. One client described the agency they had before 5K exactly that way:
We had an agency prior to 5K and that agency was good, but hit a certain plateau. I feel that 5K has taken it from that plateau and to the next level.
Getting past a plateau looks like this. SPF Screens & Awnings grew from $8 million to $22 million in its first two years with 5K, with a 38% lower cost per qualified lead. Ultra Bright Lightz reached a 5.84x return on ad spend on Google Ads.
You wouldn't let an intake nurse write your diagnosis. Most free agency audits work that way: a quick checklist, a tool's output, and a pitch. The 5K Second Opinion is built differently.
