Weglot: AI Translation & SEO

I have been using this app for almost 5 years. Would I use it again for a new brand? Probably not.

There are too many complex issues when it comes to Shopify Markets and backend translations. And when you need customer support the most, you often have to wait 5 to 6 hours just to get a response by email. Guys, even in 2026, for such a big company, they still don’t offer proper chat support.

Then, after a few rounds of emailing, the person helping you is suddenly off, someone else takes over, and you have to explain the whole issue again from the beginning.

On top of that, it’s not the cheapest option. I am still using it because I don’t want to translate the whole website again.

Also, their automatic translations are pretty useless because they don’t properly respect informal or formal language. To enable that, you need to be on the Advanced plan, which I think costs around €300

The only thing I do like is that the app can detect and translate almost everything. Well, almost. You still need Shopify’s Translate & Adapt for backend translations such as checkout and email notifications.

Honestly, I would not recommend installing it. Save yourself the headache and stress. You are probably better off using Shopify Translate & Adapt.

Too expensive compared to other similar apps. Their pricing model is thought to grow exponentially. It is unsustainable if you have multiple countries and an active blog to be translated.

Uninstall doesn't clean up, caused massive hidden revenue loss months later. Plus billing kept running after removal. We installed Weglot to test internationalization on our Shopify store, decided it wasn't right for us, and uninstalled within days. Two serious problems followed:
1. They kept charging us for 3 months after we uninstalled. The app was removed from our Shopify store, but the charges continued through Shopify Billing for three full months. We had to chase them down through support to stop it and request refunds. Watch your billing statements carefully uninstalling the app from Shopify does NOT automatically cancel your Weglot subscription.

2. Hidden URL residue caused months of bot traffic and a major revenue hit. When Weglot is active, it creates locale subpaths on your domain (/it/, /de/, /fr/, /ru/, etc.) for translated content. When you uninstall, those URLs stay indexed in Google and continue to be hit by bot crawlers, AI search results, and old links — indefinitely. There's no in-app cleanup, no warning that this will happen, no instructions on how to remove the URLs from search engines.

In our case, these zombie URLs (we don't even sell in those markets) became a magnet for bot/scraper traffic. The volume was high enough that our edge layer's bot-mitigation kicked into overdrive and started returning 403 errors on cart.js for real shoppers whose network profile happened to resemble the bot signatures. Add-to-Cart silently broke for thousands of US customers across multiple devices and browsers. They saw the Add-to-Cart button, clicked it, nothing happened. They bounced. We only caught it through Noibu (an error-monitoring app), which flagged 4,165 affected sessions in a single week with zero progressing to checkout. Estimated annual revenue impact: $104k.

When we finally traced it back, the fix took manual work on our side: ~24 Shopify URL redirects, robots.txt customization, and Google Search Console URL removals — none of which Weglot helps with at uninstall.

For other merchants considering Weglot:
- Before you install, ask in writing how to fully remove URL artifacts at uninstall
- Confirm in writing how to cancel billing (assume uninstall ≠ cancellation)
- Track your conversion + bot traffic for weeks AFTER uninstall, not just during use
- The damage from URL residue can dwarf any short-term value of trying the app. We lost months of clarity on why our conversion was degrading before tracing it back here. Weglot's "easy install, easy
uninstall" framing is misleading. Uninstall is not clean
