Topic clusters vs one-page-per-keyword. The second still works — sometimes.

Topic clusters vs one-page-per-keyword. The second still works — sometimes.
Clusters are gospel now, so everyone forgot one-keyword-one-page can still win. Pick by competition depth.
— Low-competition, high-intent long tail ('how to cancel [tool] subscription'): a single tight 800-word page nails it. No cluster needed, the intent is atomic.
— Competitive head term: you CAN'T win it with one page. You need the pillar + 10 spokes proving topical depth. Google won't trust a lone page on 'project management software'.
The tell: how many ranking competitors have a whole cluster? If the SERP is single pages, match it. If it's clusters, you need one.
Look at your next target's SERP. Count the clusters.
