I find the content very easy to do or get, all I do is speak out a written article in my own wording thu a microphone translated to text.
when you get good at it can knock easy 3k to 5k size articles out, over a week easy 15 big articles with Copyscape approval and gran spelling checked.
I even reference what articles I have read to make my article look proof of the fact.
remember proof fact-based articles Google loves .
there even easer way i do a lot i use gsa app for articles and rewrite them as packing content .non fact articles
most people fail on server setup for seo before they even begin , and understanding heigh quilty links, content king but seo way more then content these days .
social exposure very important, I think social accounts with high stat numbers can index you heigh in google with very little content,
it just all diffrent these days .
sorry just my opioion .
