Hi @tomkennedy ,
In case you really want to write about working remote in digital marketing, I would recommend to use exactly that as pillar topic! It’s a great topic, not too broad not too narrow.
Your subtopics could be focused more on the detailed subjects within this core topic. Such as topics related to performing specific digital marketing activities from home.
SEO, Content marketing or Digital marketing could be pillar topics on their own.
Hope this helps and good luck creating your first pillar page!
Kind regards,
Nynke
