Joe Connonly in today's StartupJournal discusses how to get more traffic for little money. Oddly enough, he doesn't cover blogs as a possiblility.

He says:

If you use a very precise phrase in your e-marketing, you may do better, says Rob Levin, founder of New York Enterprise Report, a New York-based publication about small and midsize business. For example, instead of listing "footwear," write "track shoes." You may get only half as many hits, but they'll be from people looking specifically for track shoes. You can direct them to the precise page within your Web site, he says.

I say:

If you write often in your weblog, post reviews of footwear, track shoes, and invite comments from your customers, you will increase your visitor ship by providing real, value add content, engaging in a conversation with your customer, and from the increased visibility that blogs get you in the search space.
