How does Google select what ends up in the snippet before SERPs?

[ejcruz]

We rank on page 1 for some keywords. Pulling SEMRush reports, we discovered we were placed #1, and we thought it was out of the norm, then determined it was due to the snippet preview Google created before SERPS. Anyway to know how we can consistently be favored by Google to get the snippet preview?

I've read up a structured data markup on schema could help. https://developers.google.com/structured-data/

All input is appreciated.

You mean "feature snippet"?

Honestly - no one knows. But you can implement semantic ItemList for this and this could trigger featured snippet for your page.

PS: In first article WS have 9k featured snippets, but rank for 580 queries. LOL. -> https://twitter.com/glenngabe/status/689807106375979008
