The lead post in this series is Mastering Topical Authority: A Comprehensive Guide to Boost Your SEO.
Google does not use domain authority as a direct ranking signal, no.
So why does everyone treat it as if it’s an important metric?
Because it’s considered to be a GENERAL indication of how likely the webpages on the site are likely to rank in a Search Engine Result Page (SERP).
And based on my personal experience of publishing content to websites over time, that is true. It IS a an excellent general indication.
Why did I write such a ridiculously short blog post that doesn’t say anything you haven’t read elsewhere?
Because the topical mapping tool AlsoAsked informed me this is something people search for, so I included it in my topical cluster about topical authority for the sake of completeness.
But now I’m done with the series. I hope you found it useful.
