I read variates of content relating to the particular content I want to write. I make more deep findings as well. Then later on I take a walk to ease myself, rest a while. Before summing-up my findings in a single piece of work.
That’s a solid process, doing research first, then stepping away to clear your head before writing, usually makes the piece flow better.
For me, I also jot down quick notes or headlines while reading, so I don’t lose the main angles I want to cover. Sometimes I even draft a rough outline in HubSpot’s notes tool and then refine it into content later.
