Ground Preparation is very important before the sod is laid. This should be done several days before sod is installed. If the ground is wet and/or frozen, it is very difficult to establish a good base for the new sod.
By working up the soil, you relieve some of the compaction – creating more air spaces. Organic matter will help the water olding ability and provide some nutrients. The sod is as good as the base (soil) upon which it is laid.
Certainly there are different opinions as to the degree of soil preparation prior to the installation of the sod. Although these steps may cost more initially they will pay dividends in the future.
