The world of social media is largely a world of give and take. It literally operates on the [premise of scratch my back and I will scratch yours. This then means that you cannot really expect to be the center of attention all day every day. You will be the center of attention for a few minutes and people will give you their attention but it only means that you should also give the next person the attention required when they become the Centre of attention.
This then goes to say that if you are looking to get free likes and free followers on social media, you have to be ready to give free likes and freely follow lots and lots of people. People will definitely return the favor. Chances are high that you have already identified the audience that you have targeted on social media; those that you want to like and follow you on social media. The next step is now to start liking their photos and their posts and everything else that there is to like. Give random likes here and there; be careful to moderate it so you do not look like a stalker. The audience will definitely eventually return the favor in a big way.
