Can anybody advise some website which helps bands in promoting? I’d like to make my band more popular. Somebody gave me a link on artistecard.com Does anybody use their services? Maybe someone knows other sites, something affordable?
Promoting your band is about more than finding the right websites to use. It's about the people you meet, the interactions you have with your fans (and potential fans), the image you present, and simply the time you put into it.
Only play what you hear. If you don’t hear anything, don’t play anything.
-Chick Corea
Well put food1010.

You gotta get out there on the streets and meet people. Actual interaction builds a fanbase faster than anything.
Word of mouth is the most powerful tool you have. Other than that, all of the popular social networking sites as well as bandcamp, soundcloud and reverbnation are your biggest tools.
And we will weave in and out of sanity unnoticed
Swirling in blissfully restless visions of all our bleary progress
Glowing in radiant madness
