Create an attractive twitter theme
Though it sounds less useful, it matters a lot. Your twitter has to be unique as to stand out from the crowd. Try to make your twitter theme as creative as possible. This lets bloggers include you in their round ups on the best twitter themes. Don’t forget to choose an attractive display image for your profile as well.
There are a few twitter background galleries out there to gain some inspiration from, but if you truly want to distinguish yourself – make your own.
