One of the most powerful traffic generating features is a blog.
The more indexed pages (centered around useful content, and strategic keywords) in search engines the more traffic your website will generate.
Make sure to pass 50 indexed pages from blogging as quickly as possible. Don't stop at 50. Continue the effort. The rate at which you'll see traffic increase will be based on the frequency of your high quality blogging activities.
