No, you really shouldn’t.
If you want to update old content, don’t. Instead, create fresh content on the topic with a brand-new angle. But don’t take old content and slap a new title on it, change a few sentences, put today’s date on it so it appears at the top of your blog, and call it updated. That is a cheap trick that your audience will not appreciate.
And there is no need to resort to such tactics with that old content. If it is search engine optimized, it is most likely to appear high on search results – no matter how old it is. And you can always create new social posts or send out fresh emails pointing to those past articles.
But the point is to always look ahead when it comes to creating content. Fresh content with fresh ideas. Your target audience will value it, and you will become the go-to source for quality thought leadership.
