Frequently Asked Questions

Does Weglot affect website SEO?

Weglot is designed to be SEO-friendly — it creates proper translated URLs (either subdirectories like /fr/ or subdomains like fr.yoursite.com) that search engines can crawl and index. Each translated page gets proper hreflang tags automatically, which tells Google which language version to show in which country. Translated content is server-side rendered for Google's crawler, not just client-side JavaScript. Users have reported significant organic traffic growth from non-English searches after adding Weglot. This SEO architecture is one of Weglot's strongest advantages over simpler translation overlays that hide content from search engines.

What is the difference between Crowdin and Lokalise?

Both Crowdin and Lokalise are professional Translation Management Systems (TMS) with similar features. Crowdin has a stronger open source community and a generous free tier for open source projects. Lokalise tends to have a cleaner, more modern interface and stronger developer experience with its CLI and API. Lokalise starts at $120/month for commercial use vs Crowdin's $50/month — making Crowdin more accessible for smaller teams. Both integrate with GitHub, GitLab, Figma, and major CI/CD pipelines. The choice often comes down to team preference after trialing both.
