Can anybody explain how exactly Outbrain works?

[lootmeup]

Upon submission, more than 50 algorithms go to work in tandem to recommend each piece of content to the most interested readers across our network. For several days after submission, each piece is placed in an “exploration phase” to try and appeal to as wide an audience as possible.

During this phase, your campaign will be prioritized to help with scaling. The Exploration Phase is also an important indicator on how successful your campaign will be. If you notice that your campaign isn’t performing well during this phase, there could be some factors causing it.

All these upon application??!!
