i've always updated my content for relevancy purpose. And there are few posts where I ranked 1 before but for some reasons I just couldn't rank that post. So I tried to check what's going on. Looks like Google has decided to show my published date to 2013 which is ironic as my site was created in 2015.
I've done all sorts of internal linking and even send links from relevant sites. But still it seems like G doesn't want to change that date.
Anyone having to dealt with that sort of issue?
