There is no specific timeline to be seeing results. It all depends on the digital marketing strategies used, the money spent on it, the effort of the digital marketers and also other unseen circumstances. All these will determine the time likely to be seeing results from any of the digital marketing strategies used.
However, the time may not be the problem, the rate of growth matters the most. It is possible to have late results but faster growth rate.
