you need to make a list of keywords suggested by various keyword suggestion tools then select few good ones out of them...
The more searches keyword has, the more difficult it will be to get traffic from it, because you're not the only one, who had noticed traffic in that keyword . Learn SEO and start practising with less competitive keywords.
