Stella, it depends what kind of website you have. You could use social media to get more traffic. Just be careful there as well because Facebook etc won't work for something like a corporate company but might work better for an English school.
You can try reciprocal linking at first, to get things rolling - with relevant websites of course. Be careful as to which sites you choose though.
There is a tutorial here:
Internet marketing tools from Interleado, an Internet Marketing company specialising in automating your web site marketing strategy that might help you out too.
Generally, I would agree with Azher though, you just have to be careful as to where you link out as well.
