I want to start an online business. Why would I want to guest post?

The short answer is to get in front of large audiences that include potential clients and customers. Guest posting gives you instant credibility – a popular blogger believes in you enough to give you free space on her blog to share your message. It’s an immediate endorsement. Until your own blog grows large enough to attract organic traffic from the search engines, guest posting is one of the best ways to attract qualified traffic to your online business.
