For FAQ Schema markup, do we need to include every FAQ that is on the page in the markup, or can we use only selected FAQs?

[PKI_Niles]

The website FAQ page we are working on has more than 50 FAQs. FAQ Schema guidelines say the markup must be an exact match with the content. Does that mean all 50+ FAQs must be in the mark-up? Or does that mean the few FAQs we decided to put in the markup are an exact match?

I would gravitate to marking everything up and letting Google decide what they want to show. Most of the time when you try to 'sculpt' what Google can see in terms of structured data, it usually results in a structured data spam action. Sometimes it can take weeks, months or years for that to happen - but Google always want to be given the full picture.

Google don't take too kindly to being funneled in a certain direction. Schema and rich snippet spam have been a big headache for Google since they started utilising structured data more, some stuff (like author avatars for posts in SERPs) has been entirely taken away in the past (though someone has told me recently, they have been seeing these again for Google mobile layout only).

Google do have some official guidance here:

https://developers.google.com/search/docs/data-types/faqpage

They give a microdata example of implementation: https://search.google.com/test/rich-results?utm_campaign=devsite&utm_medium=microdata&utm_source=faq-page

In their example, nothing is missing or has been left out. Since that's how Google have illustrated their example, that's what I'd aim for myself
