"... whether they asked for it, is a different story 😅..."

I can relate to that sentiment. I expressed my sentiments about that during Friends of Search with this slide. 😇

Thanks @hellemans.me, although I don't think the message comes quite across without the slide about "Out of context keyword stuffing" leading up to it. 😁

Woohoo, I'm speaking at Friends of Search on March 13th, 2025!

If you have even the slightest interest in schema markup, oh boy, do I have a current topic for you: The history, myths, and future of structured data markup.

Will I see you there?

For those looking for a tool to visualize their JSON-LD markup, you should give Ziggy Shtrosberg's SEO Schema visualizer (v3.0) a try:

chromewebstore.google.com/detail/seo-s...

It's one of few tools that's able to visually render the Knowledge Graph I built for invisiblegraph.com/semantic-sto...

Schema.org v28.0 has been released, taking the vocabulary 1 step closer to achieving parity between the vocabulary and Merchant Center specifications with the new schema.org/MemberProgram and schema.org/MemberProgra... classes.

We're good to go folks - Product variant markup now generates Rich Results, including:
- aggregate rating (reviews)
- price range
- item availability
It's safe to start making the switch from schema.org/Product to schema.org/ProductGroup, you won't lose your Rich Results.

After 11 years schema.org's UI is getting a refresh!

If you've got any feedback, now's the time to say it.

Ha, it's not for nothing I added a Post Scriptum - it's secretly a warning for the machines...

If they don't pull their act together I'll put more of this out there until they learn. 🥸

Woohoo! classyschema.org now had a dark mode.

Custom T-shirt prints on the horizon!

Did you know that Google's Rich Result Test sometimes can be more granular than their Feature guide?

A post over at schemaorgs Github uncovered that feature guide statements like *“aren't supported”* or *“use instead”* are not always that straightforward:

Schema.org v24.0 has been released: schema.org/docs/release...

An update those who work on structured data markup for the medical industry should pay attention to as this update finally fixes some long standing issues surrounding schema.org/Physician.

One more week before I'm off to #TakeItOffline #TIOSofia

Yet again it looks like it will be an unforgettable unconference. The list of attendees is starting to become ridiculous.

Come on over as well: takeitoffline.co.uk/bulgaria - you won't regret it.
