The ‘marketing glossary pages’ of MailChimp is ranking for hundreds of keywords like these:
What is ROI
What is a landing page
What is a bounce rate, & a lot more.
As a result, these pages are driving 46.3k organic visits per month and have acquired links from 1.74k domains.

Make it relevant to the business offerings. For example, if your business is in the HR services, the glossary page could be relevant to the HR glossary.
Now, it’s time to find all possible relevant sub-topics relevant to your primary idea.
Possible sources to get ideas from are:
Customer interviews
Google autosuggestions
TOC of books
Quora, Reddit, and other forums.
Surely, you don’t necessarily need to write thousands of definitions, even related to the primary topic.
Prioritize the keyword list by→
Now, you have a list of glossary terms to be considered.
Make the title as simple as ‘[keyword] definition,’ or something like ‘what is [keyword].’ Add the definition in one paragraph.
Sometimes it helps you win featured snippets as well. Next, add relevant questions to the glossary keyword.

Adding FAQ schema for the related questions will help you stand out in the SERP.
Here’s how Mailchimp is doing the same:

Internal linking is a must to get the most out of this strategy. Add internal links to relevant blog articles, pillar pages, service pages. Even better, run editorial link campaigns to get the initial boost to the glossary pages.

is the FAQ schema a good strategy to include for blogs that follows question and answer style? I have couple of glossary pages here: https://blocksurvey.io/glossary
Can you guide?
Yes, for a quick questions answer style, FAQ is always a good practice. Best part is you can drive traffic to other webpages by linking from the answers itself.
