If you’ve managed Google Ads long enough, you’ve seen this pattern.
A mature account.
Years of data.
Stable performance.
Clear systems.
Then a Google rep shows up.
Not with bad intentions. With “best practices.”
That’s where the damage starts.
The context Google reps don’t see
Google reps work off playbooks.
-
Short-term optimization goals
-
Feature adoption quotas
-
Generic account heuristics
-
Surface-level metrics
They don’t see:
-
Historical testing logic
-
Business constraints
-
Margin sensitivity
-
Lead quality nuances
-
Seasonality patterns
-
Offline conversion lag
A mature account is not a sandbox.
It’s a finely tuned machine.
Playbook advice breaks machines.
The three moves that quietly kill performance
1. Forcing automation before the account is ready
Common push:
-
Broad match everywhere
-
Maximize Conversions immediately
-
Smart bidding without clean conversion data
What happens:
-
Loss of query control
-
Spend shifts to low-intent traffic
-
Lead quality collapses before volume improves
Automation amplifies signals.
If your signals aren’t perfect, it amplifies noise.
2. Expanding “for growth” without cost discipline
Reps love:
-
New campaign types
-
New networks
-
New inventory
-
“You’re limited by budget” narratives
They rarely ask:
-
What’s your target CPA by channel?
-
Which campaigns protect cash flow?
-
Which keywords anchor profitability?
Growth without constraint is just accelerated waste.
3. Overwriting systems with recommendations
Mature accounts run on systems:
-
Intent segmentation
-
Query pruning
-
Bid caps
-
Manual overrides
-
Negative keyword discipline
Reps push:
-
Apply recommendations
-
Auto-apply changes
-
Simplify structure
“Simplification” often means deleting the very levers that kept the account profitable.
Why this happens structurally
Google reps are not operators.
They are:
-
Product adoption agents
-
Feature rollout support
-
Quarterly KPI-driven
Their success metrics are not your profit.
Even good reps are misaligned by design.
This isn’t personal.
It’s incentive structure.
The real danger: slow damage, not instant failure
Most accounts don’t collapse overnight.
They drift.
-
CPA creeps up
-
Conversion quality drops
-
Search terms degrade
-
Spend reallocates silently
By the time the founder notices, the historical edge is gone.
Recovery costs more than protection.
The rule for mature accounts
If your account has:
-
Consistent conversions
-
Clear benchmarks
-
Proven profitability
-
Years of data
Then:
-
You do not hand control to reps
-
You do not auto-apply recommendations
-
You do not test blindly at scale
You gate changes behind a system.
The operator stance
I don’t “collaborate” with Google reps.
I:
-
Filter inputs
-
Extract only what aligns with the system
-
Ignore the rest
The account comes first.
Not Google’s roadmap.
That’s how mature Google Ads accounts stay mature.
