I want to bulk edit my published post dates in WordPress, but I can't manually do it as I have 300+ posts on my sites. What is the best plugin or solution to edit the dates of all my posts to a specific date? I did check @pradeepkumar 's thread about this but it ain't what I want.
Also, is it okay (SEO or Spam wise) if I edit my post dates every 2 weeks? Or 1 week?
