Word Press, as one of the most popular blogging platforms in the world, offers the ability for users to change the date on their posts, both before and after they have been published. You can set a post to appear in the future, scheduling your content drops. What about changing the date on a current post to make it look older? How can it be used, legitimately and illegitimately, and what is Google’s opinion on the practice?
On a similar note, there’s also the instance where you future-date an old article to a date that is still in the past, but more recent. Older sites with older posts tend to be ranked higher. Google and the other search engines don’t necessarily care that your post was posted two years ago.
Therefore, why not make your site look older by posting a few dozen or a few hundred articles with dates scattered across the previous months or years? What they care about is the age of your site as a whole.
They care about monitoring your actions over the course of the lifespan of your site.
Older sites rank higher because they have had more time to gain Google’s trust.
By backdating the content on a brand new site, you may be able to trick users into thinking your site has been around for a while, hidden in a place they never saw it.
