Translating a WordPress Plugin the Right Way (2026)

Plugin translation is where most sites lose maintainability. Do it wrong once and every update wipes your work.

TL;DR
  • Never edit source PO files — use a child language folder.
  • Loco Translate for solo work.
  • WPML/Polylang for full multilingual sites.
Field notes from the WBP team

One client edited PO files inside the plugin folder. Every update wiped 6 languages. We migrated to wp-content/languages and never lost a string again.

  • Use wp-content/languages/plugins/
  • Never edit inside the plugin folder
  • Commit .po + .mo together
  • Test with WP_LANG override

Inside WBP Omni SEO Pro: Dynamic XML & News Sitemaps

Dynamic XML & News Sitemaps

Auto-generated index sitemaps split by post type, language and freshness, with per-URL priority, hreflang alternates and a News sitemap for time-sensitive content.

Why this matters for "Translating a WordPress Plugin the Right Way (2026)": A single flat sitemap at scale slows discovery and hides freshness signals from crawlers and LLM indexers.

Use Dynamic XML & News Sitemaps in 4 steps
  1. 1
    Step 1

    SEO Features → Sitemap → Enable index sitemaps

  2. 2
    Step 2

    Split by CPT, language and updated-in-last-48h

  3. 3
    Step 3

    Ping IndexNow + Bing + Google on publish

  4. 4
    Step 4

    Expose the News sitemap only for CPTs you mark as news

48h → 6h
median discovery time after enabling IndexNow + split sitemaps

"Discovery is a solved problem; the plugins that still ship one flat sitemap just haven't updated the solution."

Paired module: Entities & Knowledge Graph Linking

Detects entities in your content, links them to Wikidata/Wikipedia/your Fact Bank and emits sameAs and mentions properties into the schema graph. LLMs cite pages they can disambiguate — entity linking is how you tell them exactly what you mean.

  • Enable Entities under Brand Authority
  • Review detected entities with confidence scores
  • Attach sameAs targets from Wikidata or your Fact Bank
  • Publish — sameAs propagates into the page @graph automatically
Loco or WPML?

Loco for translation. WPML for full multilingual content.

Why do translations disappear?

You edited inside the plugin folder. Move to wp-content/languages.

Do I still need to submit sitemaps in GSC?

Submit the index sitemap once. WBP keeps children current and pings IndexNow on every change, so GSC re-fetches without manual resubmits.

Do I need to hand-curate every entity?

No — high-confidence entities auto-attach on save; only ambiguous ones enter the review queue. You can also lock brand entities so they never require review.
