Well written article about writing blog posts. His basic premise is that you write timeless articles using keywords that people can find when doing searches. For example, instead of an interior designer only writing about new products (short time frame since they’re only “new” for a short time), the designer would also write articles about how to choose the right colors for a living room remodel (a post that is relevant today, in six months or in six years).
An additional advantage to writing the timeless articles is that they can be submitted to blog sites such as Digg, ezine, etc. to promote the writer as well as the blog. The article could also be used in a monthly newsletter!
