Recently I was inspired by Mike’s post, ‘Leveraging Machine-Readable Entity ID’s for SEO’, which if you haven’t checked out already you definitely should. Mike’s post shines a light on MREID’s (described as a canonical URI for an entity, issued and used by Google) and how we can look to using them for SEO. To quote Mike’s post:
A machine-readable entity ID is, in essence, a string of characters used to exclusively refer to a single entity.
According to Bill Slawski — and thanks to his tireless work analyzing Google Patents, plus, generally paying more attention than anyone else — we know that Google is using MREID across many services like Google Trends, Google Lens, and Google Reverse Image Search (to keep track of entities within images).
Once I understood what machine-readable entity IDs were (here’s an example of the one for Seattle: /m/0d9jr), I had to know more.
