Importing feeds

When a new feed is added to Tumblr, its most recent post will be imported, followed by any posts added from that point forward. Tumblr skips any entries that are more than 2 days old.

The time between updates can vary greatly depending on the service. We try to crawl feeds once every hour, but we do respect each feed's "Time To Live" (TTL) declaration which may affect the update interval.

If the dates and times on feed items are missing or are all identical, then Tumblr can't import the feed. It won't be able to tell new content from old content. If this happens with one of your feeds, we suggest you speak with the service creating the feed and ask that they add unique timestamps to it.

If you are having trouble importing a Twitter feed, please make sure that your updates are not Protected on Twitter.com. Protection means that Twitter doesn't make a feed of your updates available for Tumblr to import.
