In one sentence, describe what the following article is about:

Go to https://www.facebook.com/ (desktop) or tap the Facebook app icon (mobile). This will open your News Feed if you're logged into Facebook.  If you aren't logged into Facebook on desktop, first enter your Facebook email address and password in the upper-right side of the page, then click Log In. On mobile, you can log into Facebook by entering your email address and password when prompted and then tapping Log In. It's in the upper-right corner of the Facebook page. Doing so takes you to your Facebook profile page. On mobile, tap ☰ in the bottom-right corner of the screen (iPhone) or the top-right corner of the screen (Android). This is near the top of your profile page. This will bring up a list of your Facebook friends. On mobile, tap Friends in the menu. The top 10 to 20 friends in this list are the people with whom you have the most frequent interactions, which means that they most likely visit your profile more often than other people. Someone who has a few hundred friends is much more likely to view your profile than is someone who has a few thousand friends; this will help narrow down the list of people who are likely to be viewing your page. If you see a person with whom you don't go out of your way to interact, they're probably viewing your page a fair amount. If you receive a Facebook notification urging you to add certain people, the people in question are most likely friends of one (or more) of your most frequent profile visitors.
Open Facebook. Click your name tab. Click Friends. Review the top results. Consider each of your top friends. Look for friend suggestions.
