DIY widget (Google / DeepL / Weglot free tier)
Headline cost: zero. Real cost: lost revenue. A JavaScript widget machine-translates pages on the fly with no human review, no SEO benefit, and no hreflang. Google does not index machine-translated overlays as separate language pages, so you get none of the organic traffic uplift that real translation delivers. Conversion rates on widget-translated checkouts run 30 to 50 percent below native pages. Acceptable for a personal blog. Catastrophic for an ecommerce brand selling into four EU markets where shoppers can spot machine output in the first sentence and leave.
