I have been writing a sort of diary for quite some time (5 years) that I store locally on my computer. Now I have decided to make some if this content publicly available in the shape of a WordPress blog since I believe it can be useful for a particular niche.
My dilemma is the following; should I publish this content with the date it was created (let’s say 2012) or with the date it’s going to be published (let’s say today)?
My main concern is how this decision might affect the SEO of my new site. I wonder how Google with interpret a post dated in 2012 sitting on a site which was just launched in 2015. On the other hand it makes sense to use the creation date since some of this content might be slightly outdated and it can be useful for the reader to have that date for context.
Any solid arguments for or against using old creation dates on a newly launched site?
