Search engines crawl and record billions of public web pages, including Meetup.com.
If you list your full name or other information about you in your Meetup profile or on any public page on the Meetup site, search engines can see it.
If you find search engine results pointing to personal information on Meetup that you don't want to be publicly visible, edit the information on the Meetup site.
To edit your personal information, visit your Account page.
Once you've edited or removed your information, it will no longer appear on the Meetup site.
However, this information may still appear in search results as cached versions of Meetup pages. Search engines will update their memory of these pages the next time they crawl the Meetup site. When that happens, the search engine will replace their old copy of the page with personal info on it with the latest version which does not contain personal info.
We can't control exactly when Google or any other search engine will update their results, but it's usually within 30 days.
