To set up automatic link anchor text rotation with deep linking service is very easy to do.

If you take a look at Fig 1 below you will see there are 3 deep links. Each one of them has the same URL but different title and/or description.  When the new link trades are established the link partner will get one of those three anchor texts.

Therefore, your anchor text is randomly rotated and evenly distributed as you build links for the particular page.
