International WordPress + Hreflang architecture
A WordPress Multisite network spanning nine languages needed its regional pages correctly linked to their English equivalents for search engines, but the relationship data behind those links was incomplete and had no way to stay trustworthy as content changed. The technical challenge wasn't writing hreflang tags; it was building a reliable way to know which page was the translation of which, across independent sites, including one hosted entirely outside the network.

CodingBeings built a network-activated WordPress plugin that scans and auto-matches Pages by slug, hierarchy and title similarity, gives a human a confidence-scored review interface, and only publishes hreflang output and localized navigation once relationships are explicitly trusted. A two-layer cache keeps output fast across eight sites without hitting the database on every page load.
The result: hreflang management moved from scattered manual tags to structured, auditable relationship data, reviewable, correctable, and safe to extend with AI-assisted diagnosis without giving up deterministic validation.
