Every Canadian small-business marketer who's been running Google Ads for a few years is having the same conversation right now: the campaigns that worked a few years ago are producing fewer leads at higher cost today, and the levers that used to fix it have either disappeared or stopped working. This isn't bad luck. It's the cumulative effect of platform changes that systematically transferred control from advertiser to algorithm.

CPCs went up across the board

Cost-per-click in competitive Canadian verticals — legal, dental, home services, B2B SaaS — climbed 15 to 30 percent year-over-year in 2025. Some of this is generic auction inflation. Most of it is structural: more advertisers chasing fewer remaining clicks, AI Max and broad match expansion forcing bids into adjacent queries, and the removal of guaranteed exact-match isolation.

Performance Max moved budget into a black box

Performance Max promised cross-channel conversion at scale and delivered something closer to a budget-shifting algorithm with limited transparency. Canadian SMBs that adopted PMax wholesale lost visibility into where their budget was going — display vs. shopping vs. YouTube vs. search — and most importantly, lost the ability to exclude poor-performing placements precisely.

Broad-match expansion ate keyword control

Google has steadily nudged advertisers toward broader match types and fewer keyword controls. AI Max for Search is the latest step. The pitch is that the algorithm finds queries you wouldn't have thought of. The reality is that for most Canadian SMBs, the algorithm finds queries that look like yours but aren't yours, then bills you for them. Pure exact-match isolation is harder to defend in the platform's own UI today than it was three years ago.

The honest conversation with clients

For agencies, the right move is to set current expectations explicitly with clients. The same budget that produced X qualified leads a few years ago will produce fewer today unless something else changes — better landing pages, better offer, broader funnel. Promising otherwise is the kind of thing our Honest Representation standard exists to discourage.
