Mobile shoppers continue to visit stores and websites and buy from all locations. Two regular benchmarks that I follow just came out and shine a light on both areas and point to an evolving mobile marketplace. Physical store traffic is down, mobile traffic is up, people are spending more time in stores and buying more from mobile devices. Retail store traffic in July dropped 6% from the same month last year, according to the Euclid retail benchmark. The data is derived from measuring tens of millions of shopping trips by tracking the location and movement of smartphones. The good news for retailers is that the number of shoppers who entered a store as a percentage of those passing by increased to 8%. The bad news is that the number of shoppers who came into the store and left within five minutes increased to 9%. But fortunately for merchants is that the amount of time the majority spent in their stores increased to 27 minutes per visit. On the downside, the number of people who returned to the store more than once in 30 days dropped to 11% of all visits measured, according to Euclid.
