Trustworthiness

What is Trustworthiness?

Trustworthiness is one of the four central pillars of Google's E-E-A-T Criteria framework and describes the credibility and trustworthiness of a website or author. In the context of SEO, it's about setting signals that communicate to Google and users that the content is trustworthy, reliable, and authentic.
