A pillar page plus tightly interlinked subpages covering one subject comprehensively — the structure AI Mode citation favors.
In more depth
Example cluster: language page → pair pages → cost page → hreflang reference → setup guide, all cross-linked.

Understanding Topic Cluster helps you make better decisions when taking a WordPress site multilingual — from choosing URL structures and engines to controlling costs. Transxlate handles the mechanics (language URLs, lang attributes, caching, hreflang on Pro) so terms like this become settings, not engineering projects.
