The arrival of ChatGPT ads has opened up a new world of possibilities for advertisers, but it has also raised a number of questions. One of the most pressing questions is: which ad format will perform best? In this guide, we will explore the pros and cons of two of the most talked-about ad formats on ChatGPT: in-answer ads and sidebar ads.

The Case for In-Answer Ads

In-answer ads appear directly within the body of ChatGPT’s response. This is a more subtle, integrated ad format that can be highly effective if done right. Here are a few of the potential benefits of in-answer ads:

  • Higher Engagement: Because they are integrated directly into the user’s conversation, in-answer ads are more likely to be seen and engaged with.
  • Greater Relevance: In-answer ads can be contextually targeted to the user’s conversation, making them more relevant and less intrusive.
  • Increased Trust: If done right, in-answer ads can be seen as a helpful and valuable part of the conversation, helping build trust and credibility with your audience.

However, there are also some potential drawbacks to in-answer ads. There is a risk that in-answer ads could be seen as deceptive or manipulative if they are not clearly labeled as sponsored content.

The Case for Sidebar Ads

Sidebar ads appear in a dedicated space in the ChatGPT interface. This is a more traditional ad format, and it has a number of advantages:

  • Less Intrusive: Because they are separate from the user’s conversation, sidebar ads are less likely to be seen as intrusive or disruptive.
  • Greater Control: With sidebar ads, advertisers have more control over the look and feel of their ads.
  • More Familiar: Sidebar ads are a familiar ad format for users, which can make them more likely to be trusted and clicked on.

Conclusion

So, which ad format is right for you? The answer depends on your specific advertising goals. If you are looking to build brand awareness and engage in a more conversational form of marketing, then in-answer ads may be the way to go. But if you are looking for a more traditional, less intrusive ad format, sidebar ads may be a better choice. The future of advertising on ChatGPT is still taking shape, and we are likely to see a variety of ad formats emerge over time.
