TikTok advertising: How to get it right.

TikTok advertising has changed the game for brands of all sizes. But what grabs attention on the platform isn’t a glossy studio production – it’s fast cuts, bold visuals and a sense of realness that speaks the language of the feed. The kind of ads that work here don’t feel like ads at all – they feel like content users would actually watch on the platform.

In this guide, we’ll show you how to get TikTok ads right. You’ll learn what makes the platform tick, how to build TikTok marketing campaigns that blend in and stand out at the same time, and why native, creative-first thinking is key to success in TikTok advertising.

And to help you bring it all together? We’ll introduce you to the Adobe Express TikTok video resizer – a tool designed to make your video content fit the format and flow of TikTok, whether you’re tweaking footage to extend an already existing advertising campaign to TikTok or creating a brand new TikTok campaign. Let’s get started – are you ready to create scroll-stopping TikTok ads?

Best practices for TikTok campaigns.

TikTok marketing works best when your content blends in with what people actually enjoy watching. Your goal? Create TikTok advertising campaigns that engage, not interrupt. Here are our best practice tips for TikTok advertising campaigns:

• Go for native creativity: Skip the slick, studio-quality ads. TikTok rewards authenticity – think lo-fi, handheld footage that feels spontaneous and real.
• Hook early: The first three seconds are crucial. Use motion, on-screen text or a bold statement to stop the scroll.
• Tap into trends: Use trending audio, formats or hashtags to make your content feel current. This increases your chances of showing up on the For You Page.
• Stick to vertical: Always create content in the 9:16 format. TikTok is a vertical platform – horizontal video looks out of place and break the flow.
• Add text and captions: Many users scroll with sound off. Use captions and overlays to ensure your message still lands.
• Use playful CTAs: Instead of saying “Buy now”, try “Tap to try it yourself” or “Join the trend”. Keep your tone casual and conversational.
• Keep safe zones in mind: Use Adobe Express to make sure elements like text and graphics remain visible and unobstructed by platform constraints or overlays.

Resize a video for TikTok with Adobe Express.

One of the most common mistakes in TikTok advertising? Simply reposting a video that was made for another platform. Maybe it’s a horizontal product demo for YouTube, or a square promo clip from Instagram. But TikTok is different: it’s vertical-first, fast-paced and visually led. And if your content doesn’t feel native, users will scroll right past.

That’s where Adobe Express comes in. The TikTok video resizer helps you adapt existing content quickly – and make it feel like it was made for the platform all along. Whether you’re working with ads, interviews, tutorials or branded clips, you can reframe, re-edit and refresh them with ease.

Here’s what the TikTok video resizer can do:

Easily optimise your video content for your TikTok feed with the Adobe Express TikTok resizer:

• Resize your video to TikTok’s 9:16 aspect ratio.
• Trim or shorten longer videos to match TikTok’s ideal length.
• Crop key visuals so they stay centre-frame and don’t get lost.
• Add bold, animated text overlays to grab attention immediately.
• Optimise your visuals for mobile.

How to turn an existing ad into a TikTok-ready video:

If you’ve already created video content for other platforms, you don’t have to start from scratch. With a few adjustments, you can adapt it for TikTok and make it feel native to the platform. Here’s how it works with Adobe Express – free, easy, and fun:

1. Open Adobe Express and log in or sign up. It’s browser-based, so no download needed.
2. Upload your video content. This could be a clip from a Facebook ad, an Instagram post, or a product trailer from your site.
3. Choose the TikTok format (9:16) – the tool automatically adjusts the canvas to fit vertical screens.
4. Reframe your content. To do so, drag and crop to centre the most important parts. You can zoom in, cut background elements or reposition text so it fits the TikTok aesthetic.
5. Trim the video, if needed. TikTok video ads can be anywhere from 5 to 60 seconds long, but you should aim for 15–30 seconds – shorter is usually better on TikTok advertising. Cut any intro fluff and get straight to the point.
6. Add motion text and overlays: use animations, bold captions, CTAs or hooks that appear in the first two to three seconds. You can customise fonts, colours and animation styles.
7. Check how your TikTok ad looks on mobile, then download your final video and upload directly to TikTok.
8. Don’t just edit once. It’s smart to create 2–3 versions of the same TikTok ad with different opening lines or captions, and test what performs best in your TikTok advertising campaign.

Tip: If you want to create a completely new TikTok video from scratch, you can start with a blank design – or create your TikTok ad using one of our editable free TikTok video templates.
