high traffic website

I want to build a high traffic site. Not a blog with 10 articles and 10 visitors a day..

Which niches do you think have a high potential for a high traffic site? Here are my ideas:

- Funny pictures
- Software Directory
- Travel Reviews (?)
- Porn.. (don't want to make a porn site)

any other ideas?

This is a case study on how I built a website that receives over 100,000 visitors per month, in less than 1 year, without spending $1 on advertising.

This was done 100% through SEO and content strategy.

Before we dive in, allow me to clarify a few things:

1. The website reached over 100,000 visitors in 9 months.
2. This was a new domain, registered just a couple months before launch.
3. This was done in a language I do not read nor speak (Japanese).
4. Japanese is a non-roman character language, making it nearly impossible to use most of the popular SEO tools.

The purpose of this post is to walk you through precisely how my team and I reached this milestone, the approach we took, and show how technical SEO combined with content strategy can deliver serious results.
