One of the most powerful features of TikTok Ads Manager is the A/B testing option. This functionality enables advertisers to experiment with different variables within their campaigns to effectively optimize performance. With A/B testing, you can create up to 10 ad groups within a campaign and test various elements, including creatives, scripts, CTAs (Calls to Action), and targeting options.

For instance, you can evaluate the performance of different creatives (videos and images) to identify which resonates most with your target audience. In this article, we'll demonstrate how an AI TikTok video generator like VidAU.AI can be utilized to create up to 10 versatile ad creatives in an hour, which can then be used for split testing. We'll also share some tips on how to make the ad creation process more effortless and cost-effective. So, let's dive in!

Why Use an AI TikTok Video Generator Tool?

AI video generators allow users to effortlessly create professional-looking videos, voiceovers, and podcasts. VidAU.AI is a prime example of AI video generators, focusing mainly on creating engaging product videos and ads. Here are a few distinctive features that distinguish VidAU.AI among other AI tools:

  • It has a powerful script writer used by marketers to create engaging video scripts based on the best marketing practices.
  • It offers many unique avatars that resemble real humans and have various voices with different accents.
  • VidAU.AI also allows you to choose from many ad templates made based on high-performing ads, ensuring you get the most engaging video that resonates with your customers.
  • VidAU.AI enables you to create numerous creatives based on one previously made video. You can simply use the "Edit" feature and make as many adjustments as needed.

Recording Your Own Content vs. Utilizing AI Voice and Avatars

The TikTok Creative Center serves as a comprehensive ad library with several analytical tools and a built-in video editor. Designed to simplify your video-editing journey, it can save you from the need to invest excessive time in editing your video content. Its user-friendly editor helps make basic video adjustments like speed, text, and transitions between clips. Unlike the TikTok Creative Center, which requires you to film raw videos, VidAU.AI allows you to create high-quality video ads from scratch. Its AI Avatars tool lets you add a human-like character to your video without the need to film it.

How to Generate the Best Ad Creatives with VidAU.AI

Here’s a simple and detailed tutorial on how you can generate various ad creatives from a previously made video:

  1. Head to the "Projects" section, choose a video that you want to test, and duplicate it.
  2. Click "Edit". There are lots of editing options in VidAU.AI’s editor. Here are some of them: script, avatar, visuals, music, and CTA.
  3. Let’s say you want to test different CTAs. Then head to the CTA section and type the new text. You may also adjust the style of your CTA by choosing a different font, text color, and font size.
  4. You may also want to change the voiceover. To do this, go to the Script section and make adjustments in the Voiceover box. You can hit the "Render audio" button and get your new voiceover generated in seconds.
  5. Preview your video. If you like the result, just click the "Render" button, and VidAU.AI will make a video in a few minutes.

You can repeat this process as many times as needed to get lots of ad creatives that can be used for A/B testing. And the best part is that these TikTok ads cost you only 2 credits each, instead of 5 that you would be charged for a completely new video.

A good practice is to test at least 10 different creatives to gather sufficient data and insights. With VidAU.AI, you can make that number of video ads in less than an hour. Thanks to this method, you’ll only use a few credits instead of the 50 you’d need for 10 videos made from scratch.

When you get the results of your split tests, you can analyze the metrics that align with your campaign objectives. These can include watch time, audience engagement, ad reach, and click-through rate. Your goal is to find the ad creatives that drive the desired outcomes and resonate most with your target audience.

You’ll also be able to refine your other ad creatives based on the insights gained. Just use VidAU.AI to find ways to alter underperforming creatives and continue testing new variations to optimize your campaigns further. This method of testing, analyzing, and refining will help you achieve success not only on TikTok but also on other platforms like Instagram and YouTube.


As you can see, split testing is a great approach that can help you build successful marketing campaigns for TikTok. You can use VidAU.AI to generate lots of budget-friendly video assets for A/B testing. It allows you to create plenty of ad creatives for few credits each. Moreover, VidAU.AI can help you adjust underperforming ads for further testing.
