Because budget was not your constraint. If you were not paced out, extra budget buys you nothing except a higher position in auctions you were already winning — which costs more per lead without producing many more of them.

How do I diagnose it?
Were you actually spending your previous budget in full, consistently?
- Yes, paced out most days → budget was the constraint, and more should produce more. If it did not, something else changed at the same time.
- No, underspending → budget was never the constraint. Raising it cannot increase lead volume, because the lead supply in your area at your ranking is what it is.
That second case is most of them, and it is why the increase produced a worse cost per lead rather than more leads.
If budget was not the constraint, what was?
Proximity and lead supply. There are only so many people searching for your service near you. Budget cannot manufacture demand.
Ranking inputs — reviews, responsiveness, hours. These decide what share of the available leads you are sent, and money does not move them.
How do I tell whether budget is my real constraint?
This is the same shape as the Google Ads version of the question. There, the diagnostic is impression share lost to budget versus lost to rank:
| Pattern | Diagnosis | Action |
|---|---|---|
| High budget-lost | Genuinely constrained by money | More budget works |
| High rank-lost | Constrained by the auction or your position | More budget will not help |
LSA does not expose that split, so you infer it from whether you were consistently spending to cap.
How should I raise an LSA budget when it is the right call?
Roughly 15% steps, gated on cost per booked job at each rung. No pre-set endpoint. Step up while the cost holds, stop the moment it degrades.
A proposed increase of roughly double was flagged as too aggressive on a software affiliate account, and correctly — those campaigns were already spending to cap, so the increase was true new delivery rather than unused headroom, and it pushed spend into less efficient inventory faster than the system could re-find efficient placements.
Which number should I judge an LSA budget increase on?
Cost per booked job, not cost per lead. A 50% budget increase that brings in lower-intent leads will show a modest rise in cost per lead and a much larger rise in cost per booked job.
If you are only watching lead cost, you will under-react to a real problem.

My cost per lead looks fine but the business still isn't making money. What number should I actually be managing to?
Cost per booked job. Cost per lead is a number the ad platform can see. Read the full answer.
After I connected the Shopify Google & YouTube app, my Performance Max cost per click crashed and impressions exploded — what did it change?
It almost certainly changed what the campaign is allowed to serve on, not how it bids. A collapsing cost per click alongside exploding impressions is the signature of delivery shifting into cheap non-Search inventory. Read the full answer.
I've got multiple locations — should I run one campaign for all of them or a separate campaign per location?
Separate campaigns. Budget is the only control that cannot be reallocated by the bidder, so one campaign per location is the only way to guarantee each market gets funded. Read the full answer.
