As well as keeping your audience informed on all the latest going-ons within your company, a blog can also be utilized as a tool to promote related content, keeping your website current and encouraging return user visits. Regular posting to your website also prompts search engine crawlers to scan your site frequently, giving it a better chance of climbing the rankings table and being found by your target market.
Adapting a blog template as a help section for your website can also be an easy, user-friendly way of displaying a lot of otherwise mundane, albeit significant, information.
