Website Translation AI: How to Choose

Quick answer — Website translation tools differ by architecture rather than by translation quality. A proxy is fastest to launch and weakest for SEO, a CMS connector is best for search, and an API costs engineering time but leaves you in control.

Three architectures, one decision

Every vendor in this category is one of three things underneath, and the demo rarely makes that obvious.

The last column decides more than people expect. A proxy serves translated pages from the vendor's infrastructure, so ending the contract ends the translated site — which is a different commercial position from owning the content.

What to ask about SEO specifically

Does each language get its own indexable URL. Is the canonical self-referencing. Is hreflang emitted and reciprocal. Is the translated page server-rendered rather than assembled in the browser. Those four decide whether translated pages can rank at all, and a tool that fails any of them produces pages that exist for customers and not for search. Then sitemaps, which is where the indexing either happens or does not.

What the tool will not do

Text inside images, which is most of the visual content on a modern marketing site and needs image translation rather than a page pass.

Video, which needs dubbing or subtitles.

PDFs linked from the site, which for regulated industries are frequently the documents that matter most.

A "fully translated site" that covers only HTML text is a partial job presented as a complete one, and it is the most common gap in this category.

The thing that outlasts the tool

Your memory and glossaries.

Tools get replaced. If the accumulated approved wording lives in the vendor's system and does not export, replacing them means starting again — so portability is worth more at the point of purchase than any feature on the comparison sheet.

Ask for a TMX export during the trial, not after the contract.

Platform-specific guides

The mechanics differ by stack. There are step-by-step guides for WordPress, Drupal, Ghost, HubSpot CMS and Salesforce.

For JavaScript frameworks the question is usually rendering rather than strings: Next.js, Nuxt, React, Vue, Angular and Svelte. Server-rendered stacks such as Django and Flask use their own catalogue formats.

FAQ

What is the main difference between website translation tools? Architecture, not translation quality. A proxy serves pages from the vendor's infrastructure, a CMS connector keeps content in your system, and an API gives full control at the cost of engineering time.

What should be checked about SEO before choosing? That each language has its own indexable URL, a self-referencing canonical, reciprocal hreflang, and server-side rendering. Failing any of those means translated pages exist for customers but not for search.

What do website translation tools usually not cover? Text inside images, video, and linked PDFs. A site described as fully translated often means the HTML text only, which leaves most of the visual content in the source language.

What matters most at the point of purchase? Whether your translation memory and glossaries export. Tools get replaced, and if the accumulated wording cannot leave with you, switching means starting over. Ask for a TMX export during the trial.
