In the facebook settings page you can change the number of friends you can see in your news feed. You must be following the person to whom you want to post your comment, otherwise it will not show up in their news feed. This is also called a ‘reach limit’.
App install ads – App install ads show up when people install apps through Facebook or the Android App Store. This feature is enabled by default for everyone, but you can turn it off if you don’t want to see any more app install ads from Facebook or any other website or app using Facebook’s targeting tools
Sponsored stories – Sponsored stories are posts that appear in News Feeds as paid promotions from brands or businesses that are part of the Sponsored Stories program (and which were previously called “promoted posts”). These posts include an image with a link back to the advertiser’s website or app, along with text highlighting.
You can choose whether to make your post public or private by clicking either toggle button next to Public or Private. The default setting is Public, which means anyone who sees a post will be able to see it. If you change this setting to Private, only people who are connected to you will be able to see it—and only when they like your page or follow you!

If you want to share posts with only some people but not others, you can also set individual permissions for each person on your list by clicking on their name in the left-hand column and selecting Add Permissions from the drop-down menu that appears next.
Before you can change the reach setting, you need to be logged in. If you’re not already logged in, you’ll be asked to login.
The default reach setting is 100%. You can change this to whatever number you want by using the slider at the top of the page.
You can change the reach of your Facebook posts in the settings page.
The reach setting determines how far your posts are visible to your followers and how many people will see them. You can choose to make the post only viewable by friends or family, or you can make it viewable by everyone.
