How do hreflang attributes affect ranking?

[Substance-create]

We have a site in English. We are considering translating the site into Dutch. If we use a hreflang attribute does that mean we have to create a duplicate page in Dutch for each English page, or does Google auto-translate?  How would duplicate pages, even if they are in a different language, affect ranking?

There are a number of points to mention here:

Firstly. hreflang is not a ranking signal, and therefore it will not provide a ranking boost.

Secondly, Google will not auto-translate the pages because hreflang was implemented. You'll need to do the translation yourself.

Thirdly, you don't have to translate all pages of your website to Duth, only the ones that would make sense to translate. For example, there could be blog posts that would resonate with an English speaking audience, but not a Dutch one, so there wouldn't be a need to translate these posts. The opposite could be true too.

What hreflang does, is that it helps search engines understand which pages are meant to rank for which languages and in which countries. The actual implementation can get tricky if you have multiple languages and several countries and I would recommend looking into a few tutorials/documentation on this, including:

• Moz's hreflang guide: https://moz.com/learn/seo/hreflang-tag

• Yoast's hreflanf guide: https://yoast.com/hreflang-ultimate-guide/

• Google's documentation on hreflang: https://support.google.com/webmasters/answer/189077?hl=en

Hope that helps!
