How to automate TikTok commerce campaigns for better performance
Performance marketers: this series is for you. Practical guides to the setup, signals and strategy behind stronger Peak Season campaigns.
Commerce campaigns require thousands of decisions – which products to show, which shoppers to reach and where to optimise.
As campaigns scale, manual optimisation becomes harder to manage, especially during Peak season when demand changes quickly.
Across this series, we're exploring the fundamentals that help advertisers build stronger commerce campaigns. After building the right data foundations, the next challenge is turning those signals into smarter decisions at scale.
That's where Smart+ Catalog Ads comes in. It helps automate campaign execution in real time, using machine learning to analyse signals and identify the products, audiences and placements most likely to drive results.
What Smart+ Catalog Ads automate
Smart+ Catalog Ads helps automate key campaign decisions, including:
Which products to show
Which shoppers to reach
Which placements to use
Which creative combinations to deliver
It runs across available placements, including TikTok, Search, Pangle, Lemon8 and CapCut (availability varies by region), continuously learning from campaign performance.
The more consistent the inputs and the longer campaigns run, the more opportunities the system can identify.
Campaigns using a full Smart+ setup have seen 41% lower CPA compared to fully manual setups [1]. This reflects what happens when the system has strong foundations to learn from and enough stability to optimise over time.
Automation works best when it handles the thousands of micro-decisions humans can't realistically make at scale, giving marketers more time to improve creative, offers and strategy.
How to set up Smart+ Catalog Ads for success
Automation works best when campaigns give the system enough flexibility and budget to learn.
Budget guidance: how much to spend based on CPA
As a rule of thumb:
Daily budget: 10–30x your average CPA
Maximum Delivery / Highest Value: use at least 10x average CPA
Cost Cap / tROAS: use at least 30x average CPA
Best practices for launching Smart+ Catalog Ads campaigns
Use Smart+ Catalog Ads with the Sales objective – designed to help commerce advertisers automate product selection and delivery decisions based on performance signals.
Give campaigns enough room to learn – campaigns need sufficient budget and conversion volume to understand what's working. Limiting spend too early can restrict learning.
Keep targeting broad where possible – broad targeting allows Smart+ to explore more opportunities and identify the shoppers most likely to convert.
Keep placements broad where available and relevant – over-restricting placements can reduce the number of opportunities available for the system to find efficient delivery.
Structure assets clearly – organised asset groups help the system test different creative combinations and identify what drives results.
How long is the Smart+ learning phase, and what to avoid during it
Once Smart+ is live, one of the most important things advertisers can do is avoid unnecessary changes. The system learns from the signals it receives, and frequent adjustments can interrupt that process.
During the learning phase, avoid:
Pausing campaigns
Reducing budgets or bids
Narrowing targeting
Changing bidding strategies
As a general guide, wait until campaigns have reached around 7 days or 25 conversions before making significant changes.
Common mistake
One of the biggest mistakes advertisers make is reacting too quickly to early campaign fluctuations.Early changes in performance don't always mean something is wrong. Often, they're part of the learning process as the system identifies the strongest opportunities.Giving campaigns stability helps Smart+ learn faster and make more informed optimisation decisions.
