Whatever level your band is playing at and whatever style you play, there are some simple things you can do to increase the chance that people will remember you. With the rise of the internet it has been both simultaneously easier and harder to stand out. Whilst that may seem like a paradox, the truth is that whilst it is easier to help people find your music and discover who you are, the ease of such things has meant that there are simply more bands now on a similar level. Effectively, it has somewhat levelled the playing field.
So to stand out, you need to make an impact. Firstly, with social networking, it is important to make sure that you update regularly, and keep your site looking fresh and interesting. Also ensure that you are on as many sites as possible as some fans may choose more obscure sites to find the more interesting bands.
It can be hard to do other forms of promotion on a limited budget. Obviously the best way to be seen and to be remembered is to gig as much as possible. Having flyers and merchandise available will also help. One of the best forms of merchandise to help you be remembered is the simple badge. A badge can be as cheap or as expensive as you like, with the more expensive ones being able to be customised exactly to your logo. However, even the cheap ones are great as the chances are, if people liked you, they will either wear them or keep them on a bag or even on their wall at home.
Button badges are the best for this purpose. Button badges are cheap so you can happily give them away to every attendee and ensure that as many people as possible go away from the gig wit ha constant reminder of who you are.
