I get a lot of ideas for blog posts, but not all of them turned into actual blog posts! I have a Chrome Browser Extension of Scribefire that allows me to quickly capture an idea that I had while in my browser. I save these ideas and partial blog posts as drafts — that maybe turn into final posts.
I decided to keep track of my planned posts. I found two options that I have been testing out. The first is a free template from Blogging Wizard (see #2 for this Google Sheets option — he also mentions Trello!). Here is a screenshot of how I used this last summer:
Recently, I have been using Notion and their free Content Calendar (which very much resembles a Kanban board in Trello). Here is the screenshot of my implementation of that:
I still use the draft feature to house some of my ideas, but I feel that these other tools will give me better organization and allow me to play to move my ideas to actual blog posts. Give either or both a try to plan out your blog posts.
