There will be 10 Tier 1 301s built towards your URL from highly popular sites such as Google. In turn, each of these 10 links will have 20 shorteners built towards them.
These can then be used with GSA in order to send a massive amount of backlinks to them. The benefit of this is that it helps to raise the rankings of your site over time but it is adding a large layer of protection towards it. The domain authority from these shorteners will really help to increase the ranking of your site!
I would recommend that you point backlinks towards the second Tier of shortened URLs.
Ranking can take time with this method due to the nature of how powerful they are, and they are a great way to increase the DA and PA of your site.
Please note however that there are no ranking guarantees provided since it is impossible to guarantee this. Due to this, no refunds will be provided.

Tier 1- 10 Links Tier 2- 20 links to each Tier 1 link.
