I published this case study back in February, but I think some people have already started translating content. As usual, there are hidden pitfalls.
vse-o-tattoo.ru simply translated its content into other languages and got an explosive surge in traffic. According to Ahrefs, traffic went from 30k to 330k. That’s an 11x growth, and in reality, it could be even higher.
Among the small details: it sets the hreflang tag for other languages, the site has authority, which means low-quality content performs better.
P.S. Everyone has started translating their old websites.
