When you publish a blog you have the option of including — or not including — the date of the publication of your posts.
My recommendation: include the date.
If you’re not publishing on a frequent, regular basis, the temptation is strong to not include the date. Resist the temptation. Your readers won’t hold it against you if you’re not writing on every Tuesday and Thursday. They don’t care if you write once a month.
But readers do want to know the publication date of the post they’re reading. They want to know how fresh the post is. They want to know if the knowledge you’re sharing is current — or not.
When you don’t include the date, readers are going to go looking for it — and that annoys them. They’ll scroll down to the comments to check the timestamps. If there aren’t any comments, they’ll assume it’s an old post.
So don’t get clever. Include the date.
