📊 Metrics & Bidding

The numbers that decide what you pay. Benchmarks live in our TikTok Ads Cost guide.

CPC — Cost Per Click
What you pay each time someone clicks your ad. TikTok 2026 average: $0.50–$1.00.
CPM — Cost Per Mille
Cost per 1,000 impressions. TikTok averages $6–$10 — usually cheaper than Meta.
oCPM — Optimized CPM
TikTok's default for conversion campaigns: billed per 1,000 impressions, but delivery targets users likely to convert.
CPV — Cost Per View
Cost per 6-second (or 2-second focused) video view. Typically $0.01–$0.04.
CPA — Cost Per Acquisition
Cost per conversion (purchase, lead, install). TikTok range: $15–$50 depending on vertical.
CPI — Cost Per Install
App-campaign CPA variant. TikTok delivers some of the cheapest installs: $2–$8.
ROAS — Return On Ad Spend
Revenue ÷ ad spend. ROAS 3.0 = $3 back per $1 spent. The north-star metric for e-commerce.
CTR — Click-Through Rate
Clicks ÷ impressions. A healthy TikTok CTR is ~1%+; below 0.8% usually means creative fatigue.
CVR — Conversion Rate
Conversions ÷ clicks (or ÷ impressions, depending on report). Driven by landing page and offer quality.
Frequency
Average number of times one user sees your ad. Above ~4/week, expect fatigue and rising CPAs.
Lowest Cost (bidding)
Default strategy: TikTok spends your full budget for maximum results, no bid input needed. Best for beginners.
Cost Cap (bidding)
You set a target average CPA; TikTok tries to hold your average near it, trading off delivery volume.
Bid Cap (bidding)
Hard maximum bid per optimisation event. Maximum control, minimum delivery. For experienced buyers.
Learning Phase
The exploration period after launch. Exits after ~50 conversion events per ad group; expect volatile CPAs until then.
Billing Threshold
The accumulated spend level at which TikTok charges your payment method (thresholds rise as trust builds).

🎯 Targeting & Audiences

Who sees your ads — and how TikTok finds more of your buyers.

Custom Audience
Audience built from your data: customer lists, website visitors (via Pixel), app activity, or ad engagers.
Lookalike Audience
TikTok finds new users statistically similar to a source Custom Audience (e.g. past purchasers).
Retargeting
Serving ads to users who already interacted — viewed your video, visited your site, added to cart. Requires the Pixel.
Broad Targeting
Minimal targeting inputs; the algorithm finds converters itself. Recommended starting point in 2026.
Interest & Behavior Targeting
Segments based on content interaction categories (e.g. beauty, gaming, cooking) and engagement behaviours.
Audience Exclusion
Removing segments (e.g. existing customers) from delivery to avoid paying twice for the same person.
Automated Targeting
TikTok adjusts audience automatically based on campaign performance; part of Smart+ automation.

📡 Tracking & Measurement

Signal quality decides your CPA. Setup walkthrough: Pixel & Events API guide.

TikTok Pixel
JavaScript snippet on your site that reports page views, add-to-carts, purchases and more back to TikTok.
Events API
Server-side connection sending conversion events directly from your backend — resilient to ad blockers and browser limits. Running it with the Pixel lifts ROAS ~19%.
Advanced Matching
Hashed customer data (email, phone) attached to events to improve attribution match rates.
Standard Events
Predefined event types: ViewContent, AddToCart, InitiateCheckout, CompletePayment, etc.
Custom Events
Your own defined events for actions outside the standard set (e.g. "quiz_completed").
Event Deduplication
Matching browser + server events by event_id so conversions aren't double-counted when running Pixel + Events API together.
Attribution Window
How long after a click/view a conversion is credited to the ad (e.g. 7-day click, 1-day view).
Post-Purchase Survey Attribution
"How did you hear about us?" data used to validate platform-reported conversions — useful since iOS privacy limits.
