Googles John Mueller stated in an SEO hangout last Friday that it is impossible for Google to understand that a person piece of material is equivalent to another piece of material when those content pieces remain in different languages. So Google is basically relying on the hreflang quality supplied by publishers.Googles John Mueller was asked how does Google determine the similarity of pages at the 26:28 mark into this video.

John included “for hreflang, I believe its difficult for us to comprehend that this specific material is equivalent for another nation or another language.” John generally stated Google can not understand this.Here is the transcript: AUDIENCE: OK, so how does Google measure the similarity of pages?JOHN MUELLER: I think we do not.

However for hreflang, I believe its impossible for us to understand that this particular material is equivalent for another country or another language. Like, there are many local distinctions that are constantly possible.Here is how Glenn Gabe summed it up: More from @johnmu: But Google does attempt to comprehend the similarities between content for * canonicalization * (however that would be for the very same language). For hreflang, thats not happening when the pages remain in another language:— Glenn Gabe (@glenngabe) January 18, 2022 Here is the video embed: Super intriguing, which leads us to my next article which will be live in 10 minutes on why does not Google use MUM for this understanding?Forum discussion at Twitter.
