The ranking factors associated with keyword staking may change in time, but at the launch of the platform this is the way things work:A user types in a keyword or key phrase, let’s say it’s “Toronto Real Estate”.The ad server will look to find any ads where the advertiser has used the exact term “Toronto Real Estate” as their trigger keyword.It will then look to see how many PRE tokens are staked or locked to the keyword, and whichever advertiser has staked the most PRE will have their ad displayed.Now, if there are no matches for the exact term “Toronto Real Estate”, it will break the phrase down into individual terms, so it will find ads with the keyword “Toronto” or “Real” or “Estate” and it will pick whichever ad has the most PRE tokens staked to it and display it.
