Before that, Facebook did not allow individuals or pages to apply for authentication on their initiative. Facebook could only find and actively give page authentication and did not authenticate their home pages.
I accidentally found that Facebook published a guide for applying for a certification badge, which may also be the reason why many of the recent advertisements run on the certification page. You should know how scarce the certification page was before that.
The following are official documents:
The certification badge means that Facebook confirms that this public homepage or personal homepage is the real public homepage or personal homepage of the public figure or brand it represents.
Authenticate your personal or public homepage
You can fill out this form to authenticate your home page or public home page.
What are the requirements for applying for a certification badge?
We will comprehensively consider various factors to evaluate the Facebook public homepage and personal homepage to determine whether they meet the public interest and our certification standards.
In addition to complying with the Facebook service terms and social codes, the public homepage and personal homepage should also comply with the following requirements:
Real: represents real users, registered businesses, or entities.
Unique: is the only representative of this user or merchant. Each user or business can only authenticate one public homepage or personal homepage, except for language-specific public homepages and personal homepages. We do not certify public and personal homepages that represent public interest (e.g. Puppy Memes).
Complete: There are introduction sections, photos of public or personal home pages, and recent developments, including at least one post.
Well-known: represents well-known users, brands, or entities with high search frequency. We will review the public homepage and personal homepage mentioned in multiple news sources, and will not review paid or promotional content as news sources.
If your public home page or your home page does not meet the criteria for obtaining a certification badge, you can show its authenticity to users by other methods.
For example, you can provide a link to your account on the official website, your Instagram home page, or your Twitter account.

Is there a place to buy the certification homepage?
Authentication homepage has no special advantage in advertising
