Credibility

What is Trustworthiness?

Trustworthiness is one of the four central pillars of Google's E-E-A-T 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.

The Importance of Trustworthiness for SEO

Trustworthiness is particularly important because:

• Trust as a Ranking Factor: Google prefers trustworthy sources in search results
