I have built a website for a client following Google's multi-language website guide.It allows to create a project (tutorial) in a user specified language. Depending on the project language the URL changes accordingly:For English (no /en within URL)http://example.com/project/33/my-own-traxFor Spanish (/es added to URL)http://example.com/es/proyecto/31/mastines-de-nurgleIf you switch from project in English to Spanish menu's also change to keep the page in one language. On the home page I display all projects in all languages:http://example.com/However, I find it a bit problematic for a user when menu's are switching languages when going from one project in English to Spanish to German and so on. I would like to keep the menu in a visitor's language (let's say English) even though it is browsing a tutorial in french so it can easily navigate it.Will I get penalized by Googlebot, if I apply this change?If so, is there any way to avoid it but apply suggested change?
