Take a walk and shop at your store
At the start of the day, take about 15 minutes to experience your store as a shopper. Stand in front of your store and look attentively what shoppers see. Enter your store and walk through it as a customer.
Take pictures of problem areas in shop windows, displays, counter, walkways, lights, walls and mark what needs to be corrected. In most of the cases all you need to do is tidy up, remove a few extra items, or replenish shelves. Little things like that matter a lot.
Also make sure your store is accessible and customers can navigate easily. This means you may need to make room for trolleys, strollers, and wheelchairs in your store layouts to ensure a smooth flow of shoppers.
