How to get into google auto suggest?

Hello,

I got last weel several mails, who offer to bring my company in the google auto suggest.
For example: "marketing agency" with the auto suggest "marketing agency company X".

How can this be done? What uses google for auto suggesting?

A god article about it is here: https://medium.com/@udonist/google-autocomplete-can-we-suggest-it-6e9fb9d4eed0
