Not sure exactly what you mean by over-indexing, but I’m found your post that way :).

Over indexing meaning Medium is giving priority to series over articles right now.

I think one way to do a series that you update regularly, it’s to write a numerical post. Meaning, “the 10 steps to…” or “The 5 ways that…”, etc.

And then update and add to every couple of days or once a week.

I’m going to publish one like that next week. Let’s see how it goes. 😁
