Google announced Search profiles for creators:

• Creates a page where a creator's content is pulled in from different platforms (articles, videos, social posts)
• People can follow creators using their Search profile
• Profiles also have a 'Follow on Google' button - followers will see more of their content show up in Discover
• Creators can customize profiles with an avatar, bio, website link & social links
• A Search profile *could* get you a knowledge panel

The blog announcement is kind of vague and just says creators with a "sizable following" are eligible for now.

The documentation gets specific about requirements for creating a Search profile:

• You must have a minimum number of subscribers or followers on at least one content platform:

◦ YouTube:100,000

◦ Instagram:100,000

◦ X:100,000

◦ TikTok:300,000

• You must be at least 18 years old.
• Your content must meet Google's policy guidelines.

Here's where you can get started if you meet the requirements.
