Google said it will require other search providers to pay to become one of the default options available to European users when setting up their Android device.

The company said in a blog post on Friday that European users will see a new choice screen when setting up their device, showing a list of options they can select to be their default search engine for the search box on their home screen and Google Chrome.

Google already lets Android users change their default provider at any time, but the new set up page allows them to change it when setting up their device.

Rival search engines will have to bid in a blind auction to become one of those default options, Google said. The company explained that process in a separate page on Android's website:

In each country auction, search providers will state the price that they are willing to pay each time a user selects them from the choice screen in the given country. Each country will have a minimum bid threshold. The three highest bidders that meet or exceed the bid threshold for a given country will appear in the choice screen for that country. The auction winners, and Google, will be ordered randomly in the choice screen. In the event of a tie, Google will allocate the slots randomly among the tied bidders. In the event that fewer than three eligible search providers meet or exceed the bid threshold, Google will fill any remaining slots randomly from the pool of eligible search providers. The pool of eligible providers will include those that applied to participate in the choice screen but did not submit bids.

A screen capture shared by the firm showed three alternative search providers, including Qwant, Ecosia and Yahoo. Google said other platforms can apply to be part of the new choice screen, adding it will be introduced on Android phones in Europe by early 2020.
