Welcome to the Q&A Forum

Hey 720, Links in Just Discovered Links are completely separate from Links in Mozscape/OSE. JDL "indexes URLs within about one hour of being shared on Twitter—as well as the URLs linked from those tweeted pages." As I understand it, JDL URLs are displayed in the report without regard to their value or the value (DA,PA) of the pages the links reside on.  On the other hand, URLs in OSE are not indiscriminate.  The links in OSE are the result of crawls that attempt to reach only URLs of a predefined depth/quality. I'm not sure if this is the case for your situation but (again, as I understand it), if the links that show up in JDL are found on low quality pages, it is possible that they will never show up in OSE. 30 days is the length of time a just discovered link remains visible on JDL.
