Setting an access restriction (e.g. by age or country) means people can’t access a facebook business page without a login
Having country or age restrictions switched on in your Facebook settings means non-logged in visitors have to login to view your page. Being logged in is the only way Facebook can confirm that the visitor meets the access requirements you’ve set.
The problem is this excludes any non-logged in casual visitors – even those who meet the country restrictions you set. It’s worth remembering that not everyone has a Facebook account or even if they do they may be logged in. This can be a barrier to people viewing your Facebook page.
Unless these restrictions are essential the best option is to make your Facebook page accessible to everyone. Don’t worry, visitors will still need to login to comment or like your content.
Here’s how to check these settings.
