If you want to increase your following and your reach, you should try to branch out and post on other people's blogs or even allow guest bloggers on your own site. No matter who writes for whom, you will definitely generate additional traffic. When you post on someone else's blog, make sure you include a back link to your site. Always, be willing to reciprocate for your own guest bloggers. This relationship is mutually beneficial, so as long as you're allowing a link, they should have no trouble also allowing a link.
