A client of mine desperately wants to get into the “private schools in Miami” knowledge graph. We've read as many materials as possible, including Neil Patanko’s content on the subject matter and Google’s guides on structured data, and followed their advice.
We built a WikiPedia page. We built a WikiData page. We tried scraping the structured data of the sites in the knowledge cards and building location-specific landing pages with custom schema on each.

We were even able to get the client’s site into the knowledge carousel for “prep schools in Miami” ... for a few days.

If anyone has had any success getting a site into a specific knowledge graph, please share what steps you took. Or if anyone has any general advice on knowledge graphs, please share.

Thank you!
