We are developing a site that will have several languages.
There will be several thousand pages, the default language will be English. Several sections of the site will not be translated at first, so the main content will be in English but navigation/boilerplate will be translated.
We have hreflang alternate tags set up for each individual page pointing to each of the other languages, eg in the English version we have:
etc
In the spanish version, we would point to the french version and the english version etc.
My question is, is this sufficient to avoid a duplicate content penalty for google for the untranslated pages?
I am aware that from a user perspective, having untranslated content is bad, but in this case it is unavoidable at first.
