Website page showing in Google

Publishing help SEO
1

Hello,

When I search in Google to one of my clients with a Webflow website.
site: www.rojos.nl I don’t see all of the existing website pages.

When I search literal for the page, Google shows the page!

Does anyone know how this can be?
Something with Robots.txt? Or something else?

Thank you.

Rick

In Google Webmaster do you have it directed to show all pages in search?

When I’m looking in Google webmaster tools I’ll see 21 pages (indexing).
