How to Build a TikTok Ad: Step-by-Step

TikTok Ads Manager organizes everything into three tiers: campaigns, ad groups, and individual ads. Work top to bottom and you won't miss a step.

Step 1: Set Up Your Campaign & Ad Group

Log in to TikTok Ads Manager. Click Create. Choose your campaign objective: Traffic, Conversions, App Installs, or another goal that matches your outcome.

Name the campaign and set a budget. Then move to the ad group. Define your audience by age, location, interests, and behaviors. Set your placements, schedule, and bid. One ad group holds multiple ads, so plan your creative variations now.

Step 2: Create or Upload Your Ad Creative

Click into the ad level. Choose your format: single video, carousel, or collection. Video performs best on TikTok. Upload your file. Per TikTok's video ad specifications, the recommended ratio is 9:16 vertical with a minimum resolution of 540 × 960 px.

Keep auction in-feed videos under 60 seconds.

Step 3: Add Text, Display Name, and Call-to-Action

Enter your display name. TikTok allows up to 20 characters for non-CJK languages. Write your ad caption. TikTok recommends staying under 100 characters before the "See more" cutoff. Pick a CTA button from options like Shop Now, Learn More, or Get It Now.

Captions render in a standard white font. Your copy does the heavy lifting, not font styling.

Step 4: Enter Landing URL & Tracking

Paste your destination URL. Install your TikTok Pixel or SDK so conversions register properly. No tracking means no algorithmic optimization.

Step 5: Preview and Submit

Use the in-app preview to check how your ad looks on a real screen. Confirm text and logos are inside the safe zone. Elements near the edges can get cropped on certain devices. Submit. All TikTok ads go through a review process before delivery begins.

TikTok Ad Specs & Format Requirements

Get these right before you upload. Wrong specs mean rejection or a distorted creative.

Video Dimensions & Duration

Per TikTok's ad specifications, auction in-feed ads require a minimum of 540 × 960 px at a 9:16 ratio. Maximum duration is 60 seconds for standard in-feed placements. Spark Ads, which boost existing organic posts, can run up to 10 minutes with no resolution or file-size restriction.

File Formats & Size Limits

Accepted formats: MP4, MOV, MPEG, 3GP, AVI. Maximum file size is 500 MB. Minimum bitrate is 516 kbps. Export at the highest quality your file size allows.

Safe Zones and Text Placement

TikTok overlays UI elements at the top and bottom of the frame. Keep important text and logos away from the edges. Downloadable safe-zone templates are available inside TikTok Ads Manager.

Spark Ads and Carousel Options

Spark Ads have no restrictions on resolution, ratio, or file size. They inherit the original organic post. Carousel ads support JPG, JPEG, or PNG images at a maximum of 100 KB per image, with 2 to 35 images per ad.

Creative Best Practices for High-Performing TikTok Ads

TikTok rewards native-feeling content. Polished TV-style ads underperform. Make it feel like a post people chose to watch.

Grab Attention in the First 2 Seconds

Open with motion, a bold question, or an unexpected visual. Per TikTok for Business guidance, the first two seconds determine whether a viewer scrolls past. Don't save the hook for the middle.

Design for Sound-Off Viewing with Captions

Add text overlays for your key messages. Some viewers watch with sound off. That said, TikTok's own creative research shows that ads with songs and lyrics achieve 2% higher ad recall than music-only content. Cover both bases.

Show Your Product in Action

Real-life use beats feature lists. Show the product solving a problem. Side-by-side comparisons, unboxing moments, and customer-use scenarios outperform staged product shots.

Test 3 to 5 Creative Variations per Ad Group

TikTok's guidance recommends running 3 to 5 different creatives per ad group and diversifying across 3 to 5 ad groups per campaign. Creative fatigue hits fast. Rotate variants before performance drops.
