01 — The challenge
An emergency category with no room for wasted clicks.
L'Exterminateur en Ligne sells pest-control treatment across Quebec, where the buying decision is made under stress and usually resolved the same day. The account was already profitable at 3.27× return, which is often where growth stalls: good enough that nobody wants to touch it.
The problem was mix. Seasonal pest demand swings violently by species and by month, and a single flat account structure spends the same way in a bed-bug panic as it does in an off-season week of idle research traffic.
“Our business is people panicking at ten at night. I never needed clever marketing, I needed to be there at the exact second someone decides they cannot live with this any longer — and to stop paying for everyone who was just curious.”
Illustrative quote — written by Web Tonic to put the results above in an owner’s words. It is not a statement provided by the client.
Urgency cuts both ways in a paid account. It makes the good clicks extremely valuable and the merely curious ones extremely expensive, so the discipline is in what you refuse to bid on.
02 — Our approach
Bid on urgency, not on interest.
We rebuilt the account around intent rather than around services. Emergency, same-day and named-pest searches were separated from research and price-comparison traffic, so the urgent segment could be bid aggressively while the curious segment was capped or excluded entirely.
Then we followed the season. Pest demand is not one curve, it is several overlapping ones, and budget was moved between species and regions weekly as the volume actually arrived instead of on a plan written in January.
Finally we made the conversion path match the panic. Copy answered the question the searcher was actually asking — can you come today, what does it cost — and the fastest route to a booked treatment was the most prominent thing on the page. That is where most of the ROAS lift came from, not from bids.
03 — What we did
Segment by urgency, follow the season, shorten the path.
Three moves, all of them about matching money to the moment demand appears.
Intent segmentation
Emergency traffic and research traffic stopped sharing a budget
Same-day and named-pest searches were separated from advice and price-comparison queries, so urgency could be bid hard while curiosity was capped. In this category that single split does more than any bid adjustment.

Seasonality management
Budget moved weekly, with the pests
Pest demand is several overlapping seasonal curves, not one. Budget followed the volume as it arrived — by species and by region — instead of following a plan written months earlier.

Conversion path
Answered the two questions a panicking customer asks
Can you come today, and what will it cost. Copy and landing experience were rewritten around those two, with the shortest possible route to a booked treatment. Most of the return lift came from here.
