"It takes lots of time and energy but it can be a very effective promotional tool. Matt McGee at Small Business SEM has an interesting piece of advice for SMB owners who are blogging about their industries or areas of expertise:
'If you're a small business blogger, it’s not enough to only write about your industry. If you hope to capture local traffic, you have to write about the location, too.'
The idea is that you’ll be picked up on local searches if you include information about your area, etc. That’s not going to be appropriate for everyone but it makes a lot of sense in the context, say, of realtors or small retailers in a particular shopping district or neighborhood."
