TikTok Ads for E-Commerce in 2025: Creative, Targeting and Budget Strategy

Why TikTok Is No Longer Optional for E-Commerce

TikTok passed 1 billion monthly active users in 2023. More relevantly for e-commerce brands: TikTok Shop reported over $20 billion in GMV in 2023, with the UK being the largest TikTok Shop market outside Southeast Asia.

The commercial intent on TikTok has shifted materially. Users discover products, research them, and purchase — often without leaving the app. For brands selling visually appealing, demonstrable products in the £15–£150 price range, TikTok's cost-per-acquisition is now competitive with Meta on a like-for-like basis.

Creative That Actually Converts

TikTok's golden rule: make content, not ads. The platform's algorithm deprioritises content that looks like an advertisement — aggressive overlaid text, stock footage, and corporate voiceovers kill performance.

Formats that work in 2025:

Spark Ads (boosted organic content) — take existing organic videos from your account or a creator's account and put paid budget behind them. These retain the native comment section and social proof, which significantly increases trust.

UGC-style scripts — first-person, talking-to-camera product reviews. Hook in the first 2 seconds (on screen text + audio hook simultaneously), problem/solution narrative, explicit CTA at 15–20 seconds.

Before/after demonstrations — transformation content is the highest-performing format across most product categories. Keep it honest: fabricated results damage brand trust and violate ASA guidelines.

Trend-jacking — using trending sounds and formats to increase organic distribution on paid content. Requires constant creative refresh (weekly, not monthly).

Campaign Structure for E-Commerce

We use a simplified two-campaign structure on TikTok:

Campaign 1: Broad prospecting

Objective: Conversions (Purchase). Targeting: broad age range, relevant interests, behavioural signals. Let TikTok's algorithm do the targeting — it is genuinely good at finding buyers within a broad audience.

Campaign 2: Retargeting

Objective: Conversions (Purchase). Custom audiences: website visitors (7 days), video viewers (25%+, 14 days), profile visitors (7 days). Creative: testimonial-led, guarantee-focused, discount offer where margin allows.

TikTok's attribution window is shorter than Meta's — we use a 7-day click / 0-day view attribution for more accurate reporting. The default 7-day click / 1-day view inflates numbers similarly to Meta.
