The problem with Smart+ has always been the same
TikTok's Smart+ campaigns perform well. Brands running volume on TikTok consistently see lower CPAs inside Smart+ than in manual campaigns — at least when it's working. The platform's behavioral and interest signals are strong. Creative optimization moves fast.
But the control problem never went away. If you needed to exclude a specific audience, cap exposure on TopView, or hold bids above a floor during a margin-sensitive window, you had two options: stay in Smart+ and accept whatever the system decided, or exit Smart+ entirely and lose the performance lift.
That binary ended with TikTok's Q2 2026 product update.
Module-level control: what it actually does
The update adds per-module toggles to Smart+ campaign setup. Targeting, budget, and placements each get an independent on/off switch. You can automate any combination.
This matters because the three modules are not equally trustworthy for every account. TikTok's audience modeling — the targeting module — is where the platform's edge actually lives. It finds buyers faster than most manually built lookalike sets because it draws on purchase signals, content engagement, and search behavior at the same time. Turning this off is rarely the right call.
The budget module is where most brands have had problems. Smart+ historically paced spend evenly across the day, or surged into engagement windows that looked good on platform metrics but didn't close. If you run campaigns with tight daily caps or dayparting logic during creative testing, manual budget control makes more sense.
Placements have been the most unpredictable. Smart+ placement selection pushes spend toward in-feed inventory at scale, even when account-level data shows stronger performance on Search or Pulse placements for a given product category. Now you can lock placements manually while keeping targeting and budget automated — which is the configuration most performance-focused accounts should test first.
Smart+ Automatic Placement now has a manual option too
The same update added the ability to select placements manually even when Smart+ Automatic Placement is enabled. Previously there was no placement input in automatic mode at all. Now you scope it — keep automation for creative optimization and bid decisions while specifying which placements are in play.
If your data shows in-feed and search consistently outperform TopView and Branded Mission for your product category, you can hardcode those two surfaces and let the system optimize within them.
How to sequence the module toggles
Don't change every module at once. Change one variable at a time or you'll lose the ability to identify what actually moved performance.
Start with targeting. If Smart+ has been broadening your audience faster than you want — diluting a customer suppression list or expanding beyond a tightly defined vertical — disable the targeting module, set your audience manually, and run it for two weeks before touching anything else.
Budget automation is worth testing once targeting stabilizes. TikTok's pacing has improved; it now concentrates spend into higher-intent windows rather than distributing evenly. For most accounts, automated budget outperforms manual pacing — so only override it when you have a specific reason.
Placements come last. Only lock them after you have at least 30 days of Smart+ data showing clear performance differences by placement. Intuition doesn't override the platform's multivariate optimization — data does.
One Asset Manager: the other Q2 update worth noting
TikTok also launched One Asset Manager in US beta. It brings catalog management, creative assets, and data connections — Pixel events, offline data — into a single interface instead of the current three-screen workflow.
If you've had ROAS measurement gaps because SKU mismatches between your catalog and landing pages went undetected until reporting came back wrong, this closes that loop at setup rather than at post-mortem. It's US-only in beta right now, accessible through your TikTok business account.
Four days to Prime Day
None of these updates change what matters for the next 96 hours. Prime Day runs June 23–26, and TikTok CPMs historically spike on the Tuesday and Wednesday of Prime Day week as retail media budgets flood digital auctions. If you have remaining TikTok budget this week, front-loading Tuesday spend before noon has outperformed even pacing in past events.
Existing Smart+ campaigns don't change configuration automatically — you'd need to manually edit them to apply the new module toggles. If your campaigns are stable heading into Prime Day, don't touch them.
If you're not sure which parts of your current TikTok setup are costing you control versus actually driving performance, the free audit at Gromerce breaks it down in under three minutes.
Running Smart+ where you shouldn't gives up margin. Running manual where automation would outperform costs you scale. The module toggles are the tool to close that gap.
