Here is a list of URL shorteners you can build links to. This list of High DA sites has been carefully chosen. The links are Do-Follow links and are indexable as well as crawlable.

NOTE

You should NOT build links Directly to your website with URL shortener sites, but build links to the direct links that are pointing to your main website, as a Tier 2 level of links. This helps a lot with link juice. The same applies to Social Bookmarks.
