I've audited dozens of agency-managed B2B accounts. I can usually spot the problem in about 30 minutes of looking at the change history.
90% of them haven't had a manual structural update in six months. Maybe longer.
They'll have some automations running. They'll have a dashboard with the right metrics. They'll send you a report that looks professional. But nobody is actually managing the account. It's on autopilot. Google's automations are doing the work, not the agency.
And because Google's automations are optimized for Google's revenue, not for your business, your account is slowly getting worse while the dashboard metrics look fine.
Why this happens
The economics are brutal and everyone knows it.
A senior account manager running a B2B PPC account properly probably costs the agency $100K-150K in salary and overhead. That person can probably manage 3-4 accounts really well. So the agency needs to bill $25K-40K a month per account just to break even. Most companies can't afford that. So agencies have to choose: lose money on the account, or stop doing the hard manual work.
They stop. They shift to automation and light-touch monitoring. They consolidate their recommendation engine recommendations. They click "apply" on Google's suggestions. They move the account manager to six accounts instead of three.
The client doesn't notice because the account still generates leads. The system still works. But the margin is going away quietly because nobody's watching for it.
The red flags
You can figure out if your agency is actually managing you or just watching you burn. Look for these things.
1. Your Optimization score is 95%+ and nobody ever mentions it.
This is the tell. An Optimization score of 95%+ means Google's automation is running everything. There are no outstanding recommendations because the agency already applied all of them. They're not trying to optimize. They're just letting Google do its thing.
A properly managed B2B account should have an Optimization score around 70-80%. Why? Because some of Google's recommendations are bad for B2B. You need a human saying "No, I'm not adding this placement" or "No, I'm not expanding to Performance Max." If your agency isn't rejecting any recommendations, they're not managing the account.
2. Your match types haven't changed in a year, and they're mostly broad.
Broad match is the default for accounts that aren't being actively managed. It's easy, it doesn't require keyword research, and Google pushes it hard. If your account is still 80%+ broad match and nothing's changed, your agency gave up.
A managed account should be migrating toward exact and phrase as new learnings come in. You should see fluctuation. You should see aggressive consolidation of low-value terms. If the structure is static, it's on autopilot.
3. Nobody can explain your offline conversion tracking architecture.
This is the big one. Ask your account manager to explain how offline conversions are flowing back into the system. If they say "we upload a CSV once a month" or "Salesforce is connected automatically," they don't have a real setup. They have the default setup. Which is broken.
A real B2B strategy involves a custom data pipeline. Salesforce to BigQuery to Google Ads API. Manual stage mapping. Scheduled uploads that check for anomalies. If your agency can't explain it, it's not there.
4. Your account structure hasn't materially changed, and it's organized by campaign template.
Lazy structure. Every account that hasn't been actively managed looks the same. "Search - Brand," "Search - Non-Brand," "Display - Remarketing," "Discover." It's the Google default template. No customization. No thought.
A managed account should have structure that maps to your business. Campaign organization by product margin. Geographic priority. Close-rate tiers. Application-based segmentation. If your structure looks like the template, you're being templated.
5. Your account manager changes every year, but the strategy never changes.
This is the pattern I see most. New account manager comes in, audits the account, says everything is running fine, and keeps the structure exactly the same. Then a year later, turnover happens again. Same cycle.
A new manager should do a 90-day audit and make structural changes. If they don't, they either don't know what they're doing, or they're not allowed to because the account is set to "autopilot mode" by the agency.
What a managed account actually looks like
Structural change quarterly. Not constant churn, but deliberate, data-driven moves. New campaigns launched based on search term analysis. Low-value keywords paused. Budget reallocated toward what's working.
A real offline conversion tracking setup, custom-built for your business. Not the default. Something that shows Salesforce stage progression being fed back into Ads.
A documented account strategy. Not a deck. A living document that explains why the structure is the way it is, what the KPIs are, and what would trigger major changes.
Active rejection of Google recommendations that don't fit the business. Not 95% Optimization score. Something like 65-75%, with the agency explaining why certain recommendations were rejected.
Regular searches for new keyword opportunities. Mining search term reports. Testing new queries. Expanding where there's room.
A named senior person accountable for the account's performance. Not a rotating junior analyst. Someone whose job depends on the account performing.
These things cost money. Real management is expensive. But it's also the only way a B2B account compounds value over time instead of slowly rotting.
The three questions to ask your agency tomorrow
"Can you walk me through our Salesforce to Google Ads attribution pipeline? How are offline conversions flowing back, and what stages are we tracking?"
If they can't answer this in detail, they're not managing the account.
"Why is our Optimization score at X? What recommendations have you rejected, and why?"
If they say "We apply all recommendations," they're not managing the account.
"What has structurally changed in the account in the last 90 days, and why did you make those changes?"
If they say "Nothing really," they're not managing the account.
If all three answers are weak, you need to have a real conversation about whether you want autopilot management or actual management. Because right now, you're getting autopilot and paying for management.
Most agencies will choose autopilot because the economics force them to. That's not their fault. But it's your problem. And it's worth knowing which camp you're in.
