[edit reason] Welcome to WebmasterWorld, now please go read the forum rules :) [/edit]
when I checked my website's DA it was 34. But today it is showing 33This is watching miniscule changes in the wrong place.
[My] DA was good. But after this update, suddenly dropped.
The old DA (Domain Authority) score was a flawed metric, one that ultimately even Moz admitted was an undependable predictor of how well a site might rank in Google.
The DA score was generated by a unique-to-MOZ internal algorithm that was easily spammed. The factors considered in its model were based on outmoded SEO techniques. The DA score of a site was a measure its degree of optimization to fit those factors... not a measure of the site's quality or relevance.
This update addresses what I believe was a flaw in the previous version in that it used to use metrics of sites that ranked well, inadvertently creating a metric based on sites that use SEO tactics to rank rather than a metric of quality.
That flaw in the original design may have reflected Moz's former obsession with deconstructing Google's SERPs based on correlation data. And we all know how useless correlation data is, right?
