I've noticed this exact thing too... I deliberately wrote a 'Beginner's Guide to Ninja Warrior' to replace the terrible 10 year old articles on the first page of Google... and despite it being up to date, amazing and has all the right keywords (ie, the exact things that Google says it's looking for) it doesn't even appear in the first 10 pages of Google, even though way worse articles do.
Steemit is very much being punished by Google... my article appears right at the top of Bing and DuckDuckGo... and soon Presearch will be right there hopefully correcting some wrongs.
We can only hope! :)
