According to a study by Internet marketing firm Hubspot, business blogs with more posts generate more leads. Business blogs with 0-11 posts generate a median of three leads. From 12-23 posts, the median rises to 10. But the real action takes place when a blog reaches the 52-post mark. They generate a median of 23 leads.

If you don't have a blog, you now have even more reason to start one. Hubspot claims that businesses with blogs generate 67 percent more leads than those without.

The reason? Quite simple - SEO. The more content on your business site, the better chances of being found by searchers - or leads. Of course, the quality of the blog posts comes into play. The use of keywords in titles and content, and generating back links to the company blog plays a significant role in search visibility.
