Hey @AminaMbaye
There are many ways through which you can increase your traffic through SMO. Here are some of the few strategies that i would like to share with you.
1] Facebook Traffic - You can join groups on facebook but make sure groups are genuine. Post regularly in groups, follow them and engage with your audience.
2] Twitter Traffic - Find trending topics on twitter, make maximum use of hash tags and join groups and engage with your audience.
I hope that will help you.
