First of all, if you are trying to import a full feed/RSS/XML from any of your websites/blogs (with the exception of wordpress, which I’ll make a special post later), Tumblr doesn’t offer a full import feature where you can migrate/export your full site to Tumblr. If you use the service that Tumblr has available you will only get posts that are 2 days old, and from that point on. There’s also a limit on the amount of feeds (being 5) and the amount of daily posts per feed (so you don’t spam).
How to Import Feeds to Tumblr.
- Go to Customize >>> Services
- Go to Automatically Import My…. And here you can choose the specific platform you want to have the feed/rss/xml imported into Tumblr. Otherwise just choose RSS FEED from the dropdown menu.
- Paste your site’s FEED URL and click on Start Importing This Feed.
- Save and Close
As I said there are some scripts specially written to import a full feed from wordpress or blogger into Tumblr.
