If you're concerned about the amount of data Facebook has on you, there's now a way to check. A new tool from the social network lets you see everything Facebook knows about you, and even download a copy of it all.
There is a check sign icon that appears on some Facebook pages and services. This check mark indicates that the page or service has been verified by Facebook. This means that the page or service is an official representation of a company, organization, or individual.
There is no one-size-fits-all answer to this question, as the best way to check for updates on Facebook services will vary depending on the service in question. However, a good place to start is the Facebook Help Center, where you can find detailed instructions on how to check for updates on a variety of different services.
