keep engage with others by participating in their question answers or by liking their comments or put relevant questions or having a great fun so there are plenty of ways you can do this
the sad thing is most people will ad anyone just to put the numbers up why i just will have a facebook fan page instead of regular.
There are countless fake profiles. so make sure you send requests to only those person whom you know personally otherwise you might get lost in a chain of fake members (mostly with the girl profile)
search for the names of your friends then send requests to them. just do this everyday. another is join in other social network groups where you can meet countless of friends, although you may not know them personally, you still can build a relationship with them. use your communication skills.
Play games and participate on group with same interests, likes, and things you are passionate for to make more friends and connections.
The best way is to just make your profile attractive and true to what you are with realistic pictures. Many friends will show up on your friend list asking to add you asap. Also participate in some fan pages, groups or events and be a regular commentator
LOL .. Nice and very interesting question .( how to make friend on fb ) well make your account with sexy pic of girl and send request to anyone .and see result ..you will find many friend
You can invites your friends and look out for people in groups or pages that are of same interest as you. Then you invite them to be your friends
make real friends and ask for their fb pages... make friends with them on fb... amd keep shecking on them.
You can ask your friends that you already have to spread the word to others and you will see that you will have a lots of friends in no time
You can open friends profile by clicking on the name and there you can click on Send Request button. Nilesh
