Why do you want to bump old blog posts if they are irrelevant to your readers?

You should consider your visitors first. And if your content is a temporary one, then leave it like this.

If an offer is old, would you be interested in it? I don't think so.

So, have your readers in mind when developing your blog.

THANK YOU MATE
