GO:0010735:   positive regulation of transcription via serum response element binding
Any process that increases the frequency, rate or extent of the specifically regulated synthesis of RNA from DNA encoding a specific set of genes as a result of a transcription factor interacting with a serum response element (SRE). A serum response element is a short sequence with dyad symmetry found in the promoters of some of the cellular immediate-early genes, regulated by serum.
