To enable feeds in your advertising campaign, follow these steps:

1. Go to campaign creation or editing: Log in to your advertising account and go to the section for creating or editing the advertising campaign in which you want to use feeds.

2. Enable the feeds option: Check the box next to the "Feed traffic" option to activate the use of feeds in your campaign. Note that you can use specific feeds by simply unchecking the feeds from which you do not want to receive traffic, and leaving the checkmark only on those that interest you.

3. Verify the balance: Pay attention to the balance of your advertising account. To activate feeds, the balance must be at least 70 USD (or higher if your campaign is targeted to the India Geo). If your balance does not meet this requirement, top it up to the required level.

4. Save the changes: After activating the feeds option and ensuring that the balance meets the requirements, save the changes in your advertising campaign.

After completing these steps, feeds will be enabled in your advertising campaign, and your ads will start displaying to the audience from partner subscription databases. This will allow you to expand your audience reach, get more traffic, and increase the effectiveness of your advertising efforts. Make sure to regularly monitor your account balance to continue enjoying the benefits of feeds and effectively manage your advertising campaigns.
