A gallery needs a sign-in
The gallery link alone isn't enough. Without your client's login and password, the page shows a sign-in form, not photos. Search engine crawlers don't have those details.

Search engines see only the sign-in form
Even if a search engine found a gallery address, it would get the sign-in form, not the photos. At most, Picvelo's sign-in page can appear in search results, with no client names and no photos.
Previews carry a watermark
Even a saved preview from a selection gallery carries the watermark, so it can't be published without your permission.
Only Picvelo's own pages are public
Picvelo's website, pricing and help pages are public. Your account details, clients and galleries never appear there. We don't create any public page from your account data.
