Empty or Thin Pages Can be Served if Different Content is Shown Depending on Location
Empty or thin pages may be displayed in Google’s index if different content is served based on the visitor’s location. E.g. if a full content page is served to US visitors but not to non-US visitors, the page might still be indexed as Googlebot crawls from the US but non-US visitors wouldn’t see the content.
Noindex Thin Pages That Provide Value to Users on Site But Not in Search
Some pages on your site may have thin content so it won’t be as valuable to have them indexed and shown in search, but if they are useful to users navigating your website then you can noindex them rather than removing them.
Focus on Creating Fewer Stronger Pages Rather Than Splitting Them Up

Microsites Can Be Seen as Doorway Pages
Microsites often look like a collection of doorway pages. If you are looking to build these microsites up in the long run then this might be an option, but if they don’t have value beyond driving traffic to another site, then microsites aren’t recommended for search and should be noindexed.
Google Tries to Figure Out Full Content When Encounters 206 Response Code
For pages returning the 206 response code (don’t have full content), Google follows that response code and tries to figure out the full content of the page so they can index it. Google doesn’t do anything special for this 206 response code, they try to follow the HTTP standards.
Doorway’ Pages May Result in a Manual Penalty
A large number of thin pages, with boilerplate content and nothing unique except for a few changed keywords, may be considered doorway pages which could result in a manual penalty from the spam team.
Manual Action Penalties can be Applied to Thin, Spun or Aggregated Content
Thin content penalties can be applied to sites manually by the web spam team where the entire site seems to be thin, ‘spun’, or aggregated from other sources without any unique additional value.
