How We Selected and Ranked These Providers
we evaluated every service provider on three sub-dimensions with features weighted at 0.40, ease of use weighted at 0.30, and value weighted at 0.30. The overall score is the weighted average of those three components using overall = 0.40 × features + 0.30 × ease of use + 0.30 × value. WPP Media Services separated itself through governed programmatic display optimization workflow discipline that connects targeting controls and creative delivery to measurable performance tuning cycles, which directly strengthened the features dimension.
