Is it a good idea to publish the same blog post twice?

Publishing the same post twice could lose you Google points as you would have duplicate content within your site, but if you have a post that’s worked really well for you in the past, go back to it, maybe edit it if it needs updating and publish it again. That way you avoid the duplicate content but you get the benefit of its SEO goodness twice.

(And as well as helping your SEO, it saves you having to think up new ideas all of the time too!)
