I looked up the Structured Data chapter to cite data on what % of sites use structured data at all, and what % specify any type of metadata like description, image etc, but it’s currently far more granular than that, missing the forest for the trees a bit.
Higher level stats I think would be useful (and have needed myself):
- Here there is a graph that shows what % of sites use each structured data tech. What is the union? How many websites use structured data? One would expect the chapter to start with this.
- Same with social media sharing metadata (OG, Twitter, etc.). There is a detailed breakdown, but no stats on the union: how many websites specify any social media sharing metadata? This would be very useful for any API that consumes URLs and fetches metadata. This could also be broken down by type of metadata: image, description, etc. (title wouldn’t be that useful, because technically nearly every website specifies a
- Individual technologies are broken down by type of data (e.g. JSON-LD) but it would be more useful to see this across all structured data technologies: what types of data (entities, properties) do websites need to specify most frequently?
