Targeting
One major factor to applying best practices within the SpringServe platform is to align your demand to the appropriate supply. This consists of only aligning tags that have corresponding targeting in terms of size, geo, device, etc. For example, if have set targeting for your supply tag to small player, don't apply demand with large player targeting.
Waterfall
Similarly, consider the type of demand that is most likely to fill as you add to your waterfall. Make sure to use demand that is set to a reasonable rate - do not put a $12 demand tag on a $2 supply tag because it's highly unlikely that it will fill. It is recommended to not let the size of your waterfall exceed 15 demand tags.
