Yes,
E-E-A-T is important for a brand and for the long-term development of a website. But the reality is that it’s not easy anymore. It’s no longer enough to just create a “character” on social media and claim that they are a great author. Your site needs to show
real author profiles, established accounts, and specialists who have been visible online for a long time and already have credibility.
If we talk about E-E-A-T in terms of
social presence, internal structure, contact information, author pages, etc., that’s already just the
baseline. It’s necessary simply to compete, not to automatically gain top rankings.
Still, E-E-A-T is something you absolutely need to keep working on.
High-quality articles, credible authors, and truly strong content that fully answers the user’s question are what can push a page toward strong rankings.
Of course, it helps even more
if those pages also have backlinks.
