How Does Facebook Suggest Friends
Action 1. Visit to Facebook and also see your friend's timeline. Click the down-facing arrowhead with a cog icon close to the "Message" button.
Step 2. Pick "Suggest Friends" from the drop-down list. Scroll with your friends to locate the one you intend to recommend, or enter the name into the Search bar. Click the name to highlight it for sharing. You may choose multiple friends at once to suggest more than one.
Step 3. Click "Send Suggestions" to send out the buddy suggestion. Both friends get the recommendation under their friend Requests tab, which also tells them you made the idea.
