Authority used to basically come down to backlinks. A show of hands. Not anymore.
Now authority, credibility, is more about the EAT principle (Expertise, Authority, and Trustworthiness).
This is critically important in YMYL (Your Money, Your Life).
So, stuff to do with health and finance especially.
But recent major algorithm changes have demonstrated how these benchmark criteria were applied globally to evaluate all websites.
Think of it as content quality control.
So are backlinks dead? No.
But more sophisticated ranking intelligence means they matter much less.
The sheer amount of links is a very binary metric in comparison.
Sure, links still count for something.
Don’t forget, they could deliver significant traffic singlehandedly.
But intricate calculations of authority, authenticity and sentiment bring link juice into a world of technicolor.
Boost your credibility by giving talks, in real life, or webinars and podcasts.
Create resources (like research and visuals) that people in the industry can use and link back to.
Get cited. Get mentioned for good things on industry blogs, news articles and listings.
Signals about how ‘credible’ you are will come from what others are saying about you.
As opposed to how good you say you are.
Google value that more. They don’t even have to be links, just bonafide positive association.
