Right here’s one: Shopify and Amazon have topical authority on ecommerce. Google seems to belief their data and ranks them earlier than different websites for a lot of ecommerce searches.

JohnMu's post on X saying "No, domain age helps nothing."

Supply: JohnMu on X (previously Twitter).

A single Tweet from a Google worker isn’t at all times definitive proof to disprove a rating issue solely. That mentioned, area age (and the 2 components beneath) have robust arguments towards them.

2. Bounce Charge

Google says it doesn’t use any Google Analytics data within the rating algorithm, and bounce fee is not any exception.

@methode's post on X saying "We don't use anything from Google analytics in the algo."

Bounce fee is solely the proportion of classes that weren’t engaged. The definition of an “engaged session” is one which both lasts longer than 10 seconds, has a conversion occasion, or has fewer than two web page views.

JohnMu's post on X saying "Google doesn't use domain authority."
