A lot of top rankling pages (affiliates, not authority sites) update their on-page content during, say the new year, summer, etc. They update some of their content, their page title (e.g. Blah blah UPDATED OCT 2017).
I'm thinking of automating this with a plugin that will change/rotate some of my page content every week or month.
Google will see new content on the ranking page every few days, and this will happen on 100% auto-pilot.
Think this is worth it for making a plugin…
