There's no denying that the digital world suffers from an overwhelming amount of content, but there are still plenty of unanswered queries out there just waiting to be answered.

That's why Google created Question Hub. Previously only available in India, Indonesia, and Nigeria, the search engine recently opened up the hub to U.S.-based publishers. Question Hub collects unanswered questions from its search engine and makes the data available to content creators to help fill in the gaps.

Users can search through categories to find related questions that need answers. You can also filter queries by location.

From there, users can submit answers to questions using their own content. Barry Schwartz of Search Engine Roundtable shared screenshots of the experience. Answering a question is as simple as submitting a link to a relevant article:

Question Hub also lets you track how your content is doing after you've submitted it.
