It depends on your competition and your chosen keywords.
For most niches, it makes sense to write around 6-15 long articles (>6000 words) and then a bunch of 500 word articles that lead to the big article - most of the time a guide (you're doing on-page SEO and target long tail keywords with those small articles).
But people like Brian from Backlinko also show other ways. Strategies like Backlinko's depend on the backlink structure (he writes about it here [1]). If you try to do it without caring about the backlink structure (you certainly should, too), the way I've described is the most economic (basically a hybrid solution).
