For: all plans
On Find Businesses, some businesses say Listed on nhs.uk, or Listed on facebook.com, yelp.com, a booking site like fresha.com or treatwell.co.uk, and so on, instead of showing a website.
It means the business doesn't have a website of its own on the map. Its map listing points to a page on another site instead, like its NHS page, its Facebook page, a Yelp listing, or its page on a booking site.
Why Explaindio doesn't check that page: the page belongs to the other site, not the business. Reading it would tell us about NHS, Facebook or Yelp, not about the business. So Explaindio doesn't check it for a video, and it can't make a one-click sample from it. (A one-click sample is made from the business's own website.)
What you can do:
Before, some of these businesses were missing from your results (several NHS practices could show as one). They now each show up on their own.
