You may notice that some blogs have sections with interesting write-ups on a topic related to the blog. These are guest writers who submit articles to bloggers containing a back link to their own blog sites. If the article is well written and generates interest in people visiting the blog, they are almost certain to click on the blog’s URL on the article to learn more about what the guest writer is talking about.
One tip about writing such articles is to make them both interesting and neutral without sounding like your advertising your own site. A 400-600 word articles is just fine and you can email that to as many colleagues you know have blog sites that share the same interests as yours. You’d be surprised that many bloggers would welcome having an interesting article on their site.
