For my site: https://www.mu-43.com It used to be that if I were to Google a unique or unusual thread name a few hours after it was posted, that thread would come up in the search results every time, without fail. These days, threads generally do not come up in a search, even if I wait a few days and the thread has many replies. Take for example this thread: https://www.mu-43.com/threads/deet-based-bug-spray-around-camera-equipment-bags.86372/ A search for Code: "Deet-based bug spray around camera equipment/bags..." doesn't return any results. This also returns nothing, indicating that the thread is not indexed: Code: site:mu-43.com Deet-based bug spray around camera equipment/bags I've tried Googling a lot of other threads that way, and I come up with links to the forum index where threads were linked at one time or another, or page 11 of a thread which I am searching by title, but the actual threads themselves (first page) aren't coming up like they used to. Here's what my Sitemap options look like: There are no messages or errors showing in Google Webmaster tools, and the sitemap seems to be fine: My site's direct traffic has held steady over time: But Google traffic has steadily declined: Am I missing something? Is there a better way to submit new thread URLs for indexing?
