There are TONS of ways to get traffic. The sad thing is that most people do the same old things over and over. So here are two great tips: If you are not all ready linking your blog posts to Twitter, you are missing out on traffic. You can automate this by signing on with pingvine. It's easy and a time saver (not to mention it generates more traffic). On your blog, post links to other helpful blogs (and in exchange, request that the other blog will post YOUR link on their site). Just make sure it is not a competitor to you. Most times, people will agree because it benefits both of you. These are only two ideas....I will be posting more soon (you can check my old posts for other ones too).
