If your cost-per-lead keeps climbing and nobody on your team can explain why, it is usually not a budget problem — it is a structural one. Here are five signs your account needs a full audit, not another small tweak.

1. Your Quality Score has been declining for months. This usually traces back to landing page mismatch or ad relevance, not bidding.

2. You are bidding on the same keywords as three competitors with no differentiation. Without a unique angle, you are just paying for the privilege of being compared on price.

3. Conversion tracking has not been audited since setup. Broken or duplicate conversion tags are the single most common cause of “this channel doesn’t work” — when it actually does, just unmeasured correctly.

4. Your account structure has not changed as your business has grown. Campaigns built for a $2,000/month budget do not scale cleanly to $20,000/month without restructuring.

5. You cannot say what your actual cost-per-acquisition is, only cost-per-click. If revenue attribution stops at the click, you are flying blind on the only number that matters.
