How do I get more followers on twitter?

[Marilyn Monroe]

I made a twitter account to show more people my youtube videos and my music. I only have about 15 followers and I was wondering how to get more. I share my twitter account on my youtube channel and my facebook account.

I just say lots of things people find interesting. I only follow others who I find interesting.

I use this to identify and unfollow those who unfollow me.

I have visited your twitter account and can see that you have a picture of yourself and a nice background with a lot of guitars. That is all fine, but you need to work on your bio. All you have is the same link twice. Instead you should tell people what you like about playing guitar and a little about yourself. Make it personal, people like that. If people search on twitter for the word "Guitar" they won’t find you because you don't have that word in you BIO. Another trick could be to use the #guitar or #music terms in your tweets, but remember: "don't spam" no one likes that. My last advice to you is to be patient. It takes time to get people to follow you.

I have put in a couple of link you might find nice about twitter. Good luck.
