If your cost per lead jumped for no obvious reason sometime after August 17th, you’re not imagining it, and you didn’t do anything wrong. Google did.
I’ve had a handful of client accounts start behaving strangely over the past few weeks. Same targeting, same creative, same budget on paper but bids climbing and daily spend burning through by early afternoon instead of stretching to close. If you manage your own Google Ads account for your Calgary business, or you’re paying someone who “manages” it by logging in once a month, this is worth five minutes of your time, because it’s already hitting your account whether you’ve noticed it yet or not. Google’s Update link: Changes to target based bid strategies – 2026
What Actually Changed
On August 17, 2026, Google rolled out a change to how Target CPA, Target ROAS, and Target CPC (Demand Gen) bidding strategies behave when a campaign is budget-limited. Plain Maximize Conversions without a target attached isn’t directly touched — Google says so explicitly in its own documentation. If your account is running target-based strategies, though, this is worth understanding.
Here’s the quiet loophole that just got closed. Before August 17, if your campaign’s budget couldn’t cover every auction it was eligible for, the algorithm got selective — it only entered the cheapest, highest-probability auctions to stay under the cap. The side effect: a lot of accounts were beating their stated target without anyone doing anything clever. Set a $10 target CPA, actually pay $5. Nobody complained.
That inconsistency is exactly what Google says it fixed. Now, target-based campaigns bid to hit the number you actually typed in not a quietly discounted version of it. If your target has been sitting untouched since you set it up (be honest, a lot of accounts are exactly like this), your real cost per conversion is now drifting up toward that old number instead of quietly beating it.
Before vs. After, in Plain Terms
| Before Aug 17, 2026 | After Aug 17, 2026 | |
|---|---|---|
| Stated Target CPA | $10 | $10 |
| Actual CPA delivered | ~$5 (quietly overperforming) | ~$10 (delivers to the literal target) |
| Budget-limited campaigns | Cherry-picked cheapest auctions | Bids more aggressively to hit target |
| Daily budget cap | Respected | Still respected — this isn’t overspend |
| Predictability when you raise budget | Volatile, unpredictable | More linear, as Google intended |
That last row matters: your monthly cap isn’t being blown through. Google is explicit that budget ceilings are still hard limits. What’s changing is how efficiently that budget gets spent within the cap which, if your target was stale, means fewer conversions for the same money.
The Part Your Blog Readers Actually Need to Hear
This isn’t really a “Google broke my account” story. It’s a “when’s the last time you actually looked at your bid targets” story. Google gave a six-week heads-up and a Bid Target Adjustment Tool before flipping the switch most accounts affected are the ones nobody had opened in months.
If you’re feeling this right now, here’s the fix, in order:
- Pull your actual CPA/ROAS from the last 60–90 days and compare it against your stated target. If actual was running well below target, you’ve found your exposure.
- Adjust the target down toward reality not all at once. Google’s own guidance is to move in increments under 20% at a time so you don’t trigger a fresh learning phase and make things worse.
- Check whether you actually need a target at all. If the goal is genuinely “spend this exact budget as efficiently as possible” rather than hitting a specific CPA, Maximize Conversions without a target sidesteps this whole issue.
- Look at where the conversions are actually landing, not just what you’re bidding. A rising CPC on a landing page that still converts at the same rate is a math problem. A rising CPC and a dropping conversion rate is a conversion ecosystem problem — the ad and the page aren’t working as one system anymore, and no amount of bid-tuning fixes that.
Why This Matters More for Small, Budget-Limited Accounts
Bigger accounts with generous budgets rarely hit the “limited by budget” status this change targets, they’re not constrained enough to trigger the old cherry-picking behavior in the first place. It’s the small and mid-size Calgary service businesses running $1,500–$5,000/month accounts, chronically capped, that got the biggest jolt. If that’s you, this is the exact moment to stop treating your Google Ads account as something you set up once and revisit when it feels broken.
Bottom Line
Google didn’t quietly raise your prices. It stopped quietly discounting them. The accounts that get hurt here are the ones running on autopilot with year-old targets and no one checking the actual-versus-target gap. The accounts that come out ahead are the ones auditing this now, fixing the number, and pairing tighter bidding with a landing page that actually earns the click.
