Turn public Bubble pages into indexable language destinations
Create stable language-prefixed URLs, translated crawler HTML, hreflang relationships and localized metadata while preserving the original Bubble app for visitors.
What the feature does
A URL and delivery layer — not automatic localization of your whole app
Multilingual SEO prepares public, indexable versions of selected pages. It does not rewrite your Bubble database schema, workflows, option sets, private user records or application logic.
Language URLs
Stable paths such as /fr/about and /de/pricing for selected public pages.
Canonical + hreflang
Signals connect the source page and every valid language alternative.
Localized crawler HTML
Translated headings, body copy, links and metadata are delivered as crawlable HTML.
Language sitemaps
Search engines can discover generated locale routes systematically.
What a visitor and a crawler receive
Visitor on /fr/...
The visitor receives the Bubble app plus the configured language experience. Bubble remains responsible for interactions, sessions, workflows and dynamic data.
Crawler on /fr/...
The crawler receives localized HTML for the same public page, with French content and international SEO signals already present.
Content parity still applies. A translated crawler page must represent content a visitor can access at the same locale URL. Translation is not permission to add crawler-only claims or keywords.
Setup
A reviewable international rollout
Activate FastPages first
Multilingual SEO extends an existing FastPages project. Domain routing and the selected public source routes must already work.
Confirm the source language
Choose the language in which the Bubble pages and stable public content are authored. Browser language is not a reliable source setting.
Choose up to two trial languages
During the trial, select up to two target languages and up to 50 source pages. Paid limits depend on the selected plan.
Select exact public paths
Translate only pages that should rank internationally. Avoid private dashboards, account data, forms and personalized screens.
Generate language versions
FastPages translates selected content and prepares language-prefixed routes such as /fr/pricing.
Review before promotion
Open representative routes and verify names, product terms, links, numbers and headings. Edit business-critical translations when needed.
Validate international SEO
Confirm self-referencing canonicals, reciprocal hreflang links, language sitemaps, status codes and visitor/crawler content parity.
Translation reliability
Provider fallback without silently publishing source text
FastPages can use a configured provider chain: OpenAI first, then DeepInfra, then Groq. A backup is used only when its API key is configured. Authentication failures, rate limits and temporary provider errors move to the next available provider.
If every configured provider fails, the translation job is marked failed. Source strings are not saved as successful translations.
What fallback does and does not do
- Improves availability when one provider is unavailable.
- Does not replace human review of legal, medical, brand or technical language.
- Provider output can vary; critical terminology needs consistent review.
Translation lifecycle
How a language page becomes publishable
1. Collect
FastPages extracts eligible public text and metadata from the selected source routes. Private and bypassed routes stay out of the job.
2. Match
Existing reviewed translations are reused before any provider request, reducing cost and unwanted wording changes.
3. Translate
Only missing strings go through the configured AI-provider chain. A provider error does not count as a successful translation.
4. Validate
The response must contain one valid string for every requested source string. Incomplete or malformed batches fail visibly.
5. Publish
After the selected routes complete, FastPages updates the language bundle, locale URLs, hreflang relationships and sitemap.
6. Review and refresh
Review representative pages and critical terminology. When source content changes, refresh the affected routes and verify parity again.
