Trends is usually the best way to generate high volume traffic. It involves using Google Trends to see what people are currently searching for. You use Blogger or Wordpress to write a post about the trend. Once you learn the pattern for writing for trends, the traffic will flow to your site.
It's not unusual to have several thousand unique visitors for a given trend post. However, the trend traffic is unsustainable and dries up after the public looses interest.
Advertisers pay little for this type of traffic, so unless you're dedicated to writing 10-20 daily trend posts, you may not have traffic to justify the work.
