I'm a bit confused about the layers between what is a "forum" vs. what is a "category" and what Google actually picks up. How many layers deep does Google algorhythm search for relevant content to index a page/thread? For example: sitename - forum name - individual thread or sitename - category name - forum name - individual thread I'm assuming option 1 is much better for Google. However, the number of pages are getting overwhelming. About 2/3's of my forums are for upgraded members only. However, the upgraded forums are also set to visible and I use the "show limited number of words" add-on to show some things to Google. Does anyone know how many words need to be shown publicly for Google to index the page? Is there a better way to structure this so Google can actually index the threads? Does Google index a forum set as category or only as a forum? Do you have any suggestions as to how many threads are too many before you create a new forum? Would love to hear how others are taking care of their structure.
