In the "Search Engines and Social" setting for Simplero pages, there is a switch to hide the page from search engines. Toggling the switch on sets the 'noindex' meta tag in the HTML for the page, so that external search engines don't index the page.
The page is still searchable from within Simplero using the membership site search function.
Suggestion: Have the Simplero search index also exclude content that is set to 'noindex', thereby hiding pages that the 'hide from search' toggle on, from search results within membership sites.
