SEO setting not working

Hi all

I have disabled search engines to index my freemium website, which means that my website should not be shown in any search engines. My website has no domain attached other than Wix’ freemium urlHowever, today I discovered that I had several unique visitors from Ukraine, US, Ireland and Canada (I am based in Scandinavia) within the last 90 days. Does anybody know how it is possible for them to find my website?

My website url has not been shared with anyone except for my coder and I am sure he did not share with anyone.

I hope to receive some help.

Thank you in advance.

Best regards,
Mike
