If you think there's someone who can contribute to your blog related to its niche, you can invite them through e-mail them with invitational requests to let you write in my blog. This is another part of the SEO plan which I have to, and I have to do it. It may keep my blog updated once and for all, to maintain it's PR on Google, Yahoo, Bing and Alexa. It will also increase inbound and outbound links as well. We have to make sure that our blog is set to do-follow, so that backlinks may get live on SERPS and it's worth for me and for the poster, too. Whether you get paid or not for blogging, it's still an opportunity that letting someone to post on my blog to express things in common.
