Fastest way is PPC but it could be useful if you are offering something through your blog otherwise use some free methods.
i would suggest you to update your blog daily. after every 2 months you'll find double traffic. I've done this and after 4 months, i got 3000 to 3500 unique visitors with 15000 or more pageviews per day.
You can increase visitors for your blog by targetting similar blogs and leaving comments on them with a link to your site, ensure the comment is useful or elseit will be removed by the admin, the more people see your comments and realise you know what you are talking about, the more likely they are to visit your site
Don't only focus on the level of visitors you are getting, it's pointless to worry about it if only 0.0001% are converting to do what you want them to do. Original content is key for driving traffic. But when the traffic arrives they need to find what they were looking for.
