In the past, Kantar Media Stradegy's digital capabilities are not as refined as traditional. The spend is very very low and there is an even greater time lag. In general, accurate spend (accounting for added value and make goods) and the time lag were also negative points we to be aware of when planning.
I vaguely remember using a Kantar planning tool to discover relevant, local magazines and their contacts - and thought the experience was subpar. The search navigation and reporting features were not the most user friendly and complete information was not always available. Review collected by and hosted on G2.com.
