Suggestion: Take the major holidays off from blogging, but the minor holidays I recommend not.
Most people do have today off. That means, of course, that they are BBQing and lighting or watching fireworks and spending time with family. But not in the morning. Days off always shows a boost of posts on Facebook - have you noticed? People like to leisurely start their vacation days and often that includes surfing and social media.
Use this to your advantage. Post an article or event on the morning of the minor holidays (the 4th of July, Labor Day, Memorial Day, etc.). Make sure you are connected to automatically post on FB as well, and you'll hit your readers.
Oh, and you can still take the day off. Just write your post in advance and schedule it to go up automatically.
How are you spending the 4th? Do you surf the internet on the holidays? Tell us in comments!
