TikTok is now a true conversion engine for ecommerce. In 2025, Shop ads migrated to GMV Max, Smart+ consolidated automation, and Search Ads Campaign lets you capture in‑app demand with keywords. Win by picking the right destination (Shop vs site), structuring for signal density, shipping TikTok‑native creative at volume, and respecting learning and measurement windows.

Why TikTok is now a conversion channel, not just awareness

Global TikTok Shop GMV doubled year over year in H1 2025 to about $26.2B, with the U.S. at $5.8B in the first half and live shopping share rising, according to the Momentum Works x Tabcut H1 2025 report and TechNode Global. A two‑year retrospective from Retail TouchPoints shows how Shop moved from awareness to purchase.

What changed in 2025

GMV Max is now the default Shop ad type

Starting July 2025, GMV Max replaced legacy Shop formats as the only supported campaign type when your sales destination is TikTok Shop. New campaigns should be GMV Max. See GMV Max migration, Product GMV Max, and ROI Protection.

Smart+ became the unifying automation layer

On Oct 7, 2025, TikTok announced Smart+ enhancements. Use Smart+ to speed setup and fold in creative automation via Symphony Creative Studio and the Symphony overview.

Search got serious

TikTok launched Search Ads Campaign with keyword suggestions and negatives. Separately, on July 21, 2025, TikTok removed the UI toggle for Automatic Search Placement on standard campaigns, while the placement still runs automatically.

Compliance pressure in the EU

The European Commission issued preliminary DSA findings naming TikTok for transparency issues. If you advertise in the EU, keep labeling and repository hygiene tight.

Account structures that work for ecommerce

Start with the sales destination decision

Shop‑first if your catalog performs in‑app, your price points are impulse‑friendly, or you run creator and live programs. Use GMV Max as your primary campaign, then layer Search Ads Campaign for high‑intent terms. Also consider LIVE GMV Max if you have consistent live programming.
Site‑first if you rely on bundles, subscriptions, post‑purchase upsells, or higher AOV. Use the Sales objective with Website destination, then add Catalog Ads for breadth and dynamic retargeting. Reference auction in‑feed specs.

Practical structure for signal density

Shop path: 1 GMV Max campaign per market. Split Product and Live ad groups only if you run consistent live programming. Keep budgets healthy to avoid starving learning. See LIVE GMV Max best practices.
Website path: 1 Sales campaign for Prospecting, 1 for Retargeting. In Prospecting, run 1–2 ad groups with broad targeting plus Catalog on. Constrain with negatives in a Search Ads Campaign once you see noisy queries.

Naming, exclusions, and budgets

Encode destination, objective, region, and signal in names.
Exclude purchasers and recent PDP viewers from prospecting where appropriate.
Respect learning stability. Avoid budget changes above 20–50 percent and give campaigns 5–7 days or ~25–50 conversions before judging. See learning phase guidance.

Creative that sells

TikTok ads that convert look like TikToks. Anchor to Creative Codes and use a simple hook–body–close structure. A practical roundup of what wins is here: creative best practices.

Fast frameworks to brief your team

Hook, show, proof, ask. Use a 1–2 second pattern break, show the product in use, add social proof, then make a direct ask.
Native production grammar. Shoot vertical. Use captions and on‑screen text. Stay in safe zones. For policy and specs, plan 9:16 and 5–60 seconds as the supported range. See ad format and functionality policy.
AI assist. Use Symphony Creative Studio to script, version, dub, and scale concepts, then validate with spend. Also review the Symphony overview.

Measurement and benchmarks

Respect the learning phase

Give campaigns time to stabilize, roughly 5–7 days or 25–50 conversions. For Search Ads Campaign, exclude the first 5 days from reporting. See learning phase and Search Ads reporting guidance.

Shop vs site metrics to watch

GMV Max: ROI, GMV, orders, product coverage, creative engagement, live‑assisted orders. Review ROI Protection parameters.
Website Sales: CPA, CVR, AOV, blended ROAS. Track contributions from Automatic Search Placement and keyword capture via Search Ads Campaign.
EU compliance note
If you advertise in the EU, ensure clear labeling, identity settings, and repository hygiene in line with the Commission’s DSA findings.

Playbooks you can run this quarter

Playbook 1: GMV Max Product + Live combo for launches

Run Product GMV Max for broad product coverage, then schedule LIVE GMV Max with creators or staff demos. Hold budgets steady for at least a week. Review ROI, GMV, and live‑assisted orders before adjusting.

Playbook 2: Capture in‑app demand with Search Ads Campaign

Build a Search Ads Campaign for core category and brand terms, then add negatives for unwanted queries. Use the keyword suggestion tool. Exclude the first 5 days from reporting per Search reporting and learning.

Playbook 3: Spark UGC winners, then scale with automation

Identify creator posts with strong hold and click signals, convert to Spark Ads, then scale in Smart+ to improve prospecting efficiency.

Common pitfalls and how to avoid them

Over‑targeting. Broad plus strong creative usually beats narrow stacks. Tighten only when query data shows clear noise.
Starving learning. Large budget swings or daily tweaks reset learning. Batch edits and respect the 5–7 day window. See learning phase guidance.
Weak hooks. If the first 1–2 seconds fail, your CPA will drift. Use Creative Codes and structure hooks deliberately.
Shop readiness gaps. Inventory, logistics, and PDP gaps undermine GMV Max. Align ops and creator calendars before scaling.
Ignoring search. Even if you run feed‑first, you are missing intent if you skip Search Ads Campaign.
