Welcome to the Q&A Forum

I am helping a client index lots and lots of pages, more than one million pages. They can be seen as questions on Quora. In the Quora case, users are often looking for the answer on a specific question, nothing else. On Quora there is a structure setup on the homepage to let the spiders in. But I think mostly it is done with a lot of sitemaps and internal linking in relevancy terms and nothing else... Correct? Or am I missing something? I am going to index about a million question and answers, just like Quora. Now I have a hard time dealing with structuring these questions without just doing it for the search engines. Because nobody cares about structuring these questions. The user is interested in related questions and/or popular questions, so I want to structure them in that way too. This way every question page will be in the sitemap, but not all questions will have links from other question pages linking to them. These questions are super longtail and the idea is that when somebody searches this exact question we can supply them with the answer (onpage will be perfectly optimised for people searching this question). Competition is super low because it is all unique user generated content. I think best is just to put them in sitemaps and use an internal linking algorithm to make the popular and related questions rank better. I could even make sure every question has at least one other page linking to it, thoughts? Moz, do you think when publishing one million pages with quality Q/A pages, this strategy is enough to index them and to rank for the question searches? Or do I need to design a structure around it so it will all be crawled and each question will also receive at least one link from a "category" page.
