I would like to add a little of my thoughts to the excellent answer Joseph B.
By default, the information about the website publisher set in the footer. If the information has confirmation, for example, with a link that is connected with the Google knowledge panel for organizing the publisher, then this is a signal for a high level of trustworthiness, as the Google tells us in the recommendations Expertise, Authoritativeness, Trustworthiness - EAT:
● Who (what individual, company, business, foundation, etc.) is
responsible for the website.
● Who (what individual, company,
business, foundation, etc.) created the content on the page.
Google repeats roughly the same in its What webmasters should know about Google’s core updates:
Does the content present information in a way that
makes you want to trust it, such as clear sourcing, evidence of the
expertise involved, background about the author or the site that
publishes it, such as through links to an author page or a site’s
In addition, an indication of the established and verified publisher is a Google requirement for publishers of news websites:
Visitors to your site want to trust and understand who
publishes it and information about those who have written articles.
That's why news sources on Google should provide clear dates, bylines,
information about authors, the publication, the publisher, company or
network behind it, and contact information.
Therefore, my answer to your question: an indication of a valid and verified publisher is a positive signal that indicates a high level of trustworthiness of the content of the website.
