This might sound rather simplistic, but I have used Google since it first arrived replacing the altavistas, Yahoos, Lycos, etc. (ie a little experience). I have searched using that G tool looking for Steem information and many times it is out of date, saying 10 months ago or last year ....
Now I know Google is smart enough to order material it finds by latest date, but the Steem material is not date-stamped from what I can see. I tried putting "2017-07-19 Title of My Post Next" but have not had a chance to see if it helps SEO yet. Maybe you @cryptoctopus have a new "learning a little bit more" for tomorrow? - and then let us all know if I am just a cantankerous old fool or perhaps have really discovered a need here?
