Any basic article or guide on improving SEO will state that posting original content on a regular basis is a crucial part of any content delivery. As a small business owner and artist, I create content for two blogs and my time is precious.
I depend on scheduling posts so that when I have time to work on the blogs, I'm making content for the future. A great example of content that works well for this this is my Wednesday series on my art blog. I share a random page from one of my sketchbooks, so I can create these posts in bulk -- I spend hours scanning my sketchbooks and processing them to be web friendly. Then I take it one step further and create literally months of blog posts at a time.
Here on the monkey blog I can spend one work day scheduling my bi-weekly typography blogs for the rest of the month. In fact, I'm writing this post on Sunday night since I know I have a busy week ahead!
We use the Drupal scheduler module which offers the ability to choose a date and time for your post to be published. Drupal 7 users will find these controls down in the lower left vertical tabs when adding content.
For the non-Drupal users, I found these options that look like they extend Tumblr, Blogger, and Wordpress to have this functionality too.
So create content when it's convenient and let auto-publishing help you reach your publishing goals!
