Is your blog doing what you want it to do? Are readers finding you? Does your blog service give you the stats you need to even know this? What is the purpose of blogging anyway?
Other than being a fun and creative way to express yourself, blogging is a way to get your message out there and to show that you are an expert in whatever you are an expert in. The key is to make sure your message reaches whoever you are trying to reach, the niche market specific to your product and/or your message.
From an internet marketing perspective, here are some of our suggestions for what features to look for:
Search engines get pinged - when you update or post a new article, all the search engines should automatically get pinged.
Allows search by categories - If you have a lot of content organized around any number of categories, it is great to have a link to a page that displays all the articles assigned to a particular category
Display by author -if you have multiple authors for your blog, the blog would show a list of the authors with a link to a page that displays the articles written by that author
