WooRank detects structured data on a website by reading one of three formats:
Our backend then extracts structured data that is using either Schema.org or Microformat vocabularies.
The Schema.org and Microformat items detected and extracted from a website will be displayed in the Structured Data module of a website’s Project or Review.
As it is grey, Microformats detection is purely informational and does not impact a website’s WooRank score. The presence of Schema.org is taken into account when calculating a website’s score.
