Translating a website into Spanish means deciding which Spanish first, then handling the mechanics: detection, machine translation, SEO, and a human pass on the pages that matter most.
Set up Weglot
- Install: a JavaScript snippet or a CMS plugin (WordPress, Shopify, Squarespace). See the WordPress guide.
- Pick a URL structure: subdomain (
es.yoursite.com) or subdirectory (yoursite.com/es/), then update your DNS. - Let it scan and translate: Weglot detects your text, images, and metadata and runs them through DeepL, Google Translate, or Microsoft Translator.
- Edit and set SEO: adjust translations in the visual editor, and confirm hreflang tags and translated URL slugs are in place.
That covers getting a Spanish version live. It does not decide which Spanish, or catch the terms a machine gets wrong at scale, which is where AI Glot comes in: a separate tool for the exported file, not a Weglot plugin.
Why Spanish expansion teams choose AI Glot:
Spanish has a decision the other languages on this blog do not have, and it comes before any tool: which Spanish.
- Spanish is not one market. European Spanish uses vosotros, ordenador and coche. Mexican and the other Latin American variants use ustedes, computadora and carro. Neutral Spanish is a convention rather than a dialect: regional vocabulary and idiom are stripped out so that any Spanish speaker reads it without friction. Naming the variant you want is part of the instruction, so it is decided once and applied to the whole export rather than drifting row by row.
- Neutral for the long tail, market-specific where it earns. Documentation, help centre, interface strings and product catalogues are fine in neutral Spanish. Homepages, campaign copy and legal pages are not, because tone and the law behind them differ between Spain and Mexico. Every variant is a full second pass over the same words, which is why the decision belongs before the budget. The real cost of Spanish translation breaks the numbers down.
- One vocabulary across both variants. If you do end up running Spain and Mexico separately, your product names, feature names and technical terms should not diverge between them. Glossaries live in the workspace rather than inside a single job, so the terms your team agreed on are written down in one place and applied automatically to the files that follow.
The round trip
- Export your Weglot translations as CSV.
- Run the file through AI Glot: describe which columns to translate and which variant of Spanish, and IDs, URLs, and prices stay untouched.
- Re-import into Weglot.

Conclusion
Weglot gets a Spanish version of your site live fast. Deciding which Spanish, and keeping terminology consistent once you have more than a handful of pages, is what a glossary and a second pass through AI Glot are for. Budgeting the project first?
