The bid amount for ChatGPT Ads can be changed at the Ad Group level. Below are the step-by-step instructions to change the bid amount for Ads in ChatGPT Ads Manager:
1. Open ChatGPT Ads Manager at https://ads.openai.com/
2. Click on "Campaigns" in the left menu. You may go directly to Campaigns management pager directly as well - https://ads.openai.com/manage/campaigns
3. Click on the specific Campaign for which you want to increase the bid amount.
4. You will see the Ad Groups within the selected Campaign. Click on the Action menu next to the Ad Group name and select the option "Edit Ad Group".
In the Ad Group settings, you can change the bid amount.
Keep in mind that if you bid a very low amount, your Ads may not show up in the ChatGPT feeds. At the same time, if you quote too high an amount, you will end up losing money unnecessarily by overpaying. From my experience with ChatGPT Ads, I suggest you start with a low bid and keep watching the impressions and clicks you are getting. If your daily budget is not fully utilised, or if you are not getting enough impressions, then increase the bid amount step-by-step and find the optimal bid amount.
