Schedule posts automatically. If you use Blogger you can schedule your posts to go live at anytime. When you write a post look at the bar on the right, click schedule, select set date and time, and then click publish once you've put in that information.
Keep a calendar of when posts are going up. I keep my blog posts organized on my iCalendar. Along with all of my work and school obligations, I have a separate iCloud calendar labeled "Blog" so I can get a monthly view of what is being posted when.
This is the basic way that I keep my blog posting schedule organized and ready to go! If you're interested in learning about how I formulate posts you can check it out here. Also, leave comments if you want to know how I organize my social media!
