Field-level vs entry-level localization
NOTE: You must be an organization or space admin in order to set up localizations.
Field-level localization and entry-level localization are the most common ways that users set up localization within Contentful, but what is the difference between the two? Why would you use one over the other? This article will help demystify these localization strategies so you can choose the ideal approach for your project.

Content type-level and space-level localization are also possible. While they offer more flexibility than either field-level or entry-level localization, they also require much more overhead and maintenance. As a result, they exceed the scope of this article, but you can find out more about those approaches in our developer documentation here.
Field-level localization
Do you frequently publish content in multiple languages at the same time, such as a bi-lingual blog? Then you’ll find field-level localization is probably the best fit for you. Field-level localization works best when your goal is to publish your translated content at the same time as your default language content. Organization admins can configure which fields on which content types support localization. For example, you may want the page title to be localized but have the same value in the event date field for all translations of an event page. So, if you have an event happening on Halloween, the event date for all translations will be Oct. 31st. Field-level localization also has the added benefit of letting you see multiple locales at once on the same screen, which isn’t possible with entry-level localization.

Entry-level localization
With entry-level localization, you can maintain a separate version of your content for each market.
Entry-level localization entails setting a content type that serves as the container for your localized content. For example, if you have an article content type, you could call the container content type "Article - Global". That content type would only need two fields:
Title (which would be used within your space in order to find this content later)
A multi-reference field that will contain the localized articles
You would then create a separate content type that you would use for the localized content. This content type would then be referenced in the multi-reference field of the container content type ("Article - Global" in this example).
With this workflow, you can maintain independent versions of your content per market while also enabling your regional teams to work autonomously.
Article with only one translation published
Article with two translations published
With entry-level localization, the main drawback is governance. Unlike field-level localization, you cannot restrict a user to just one locale. This means a user can create entries in any of the locales that you have configured. However, you can mitigate this by preventing users from attaching those articles by setting up specific content permissions.
