As we shift to online shopping we are seeing that it is easier than ever to track the shopping trends.  Gone are the days that you can simply open up a store and hope.  People have choices these days and with the choices you have some stiff competition coming in all directions.   The best retailer will win the sale.  However, it is important to pay attention to all the aspects of that sale.  What was the packaging, how was it presented, and the price point?  Sometimes it is something as simple as changing the packaging to make more sales.  However, there are many factors that go into a sale.  Managing all this data can be overwhelming to some.  Which is why there are actual companies, such as https://mobileinsight.com/ that do this for you.  
Check for patterns and trends
If you want to follow the patterns and trends, it is important to gather as much data as you can about your customer's experience and what led them to the sale.  Things such as where they live, how much they make, their race, or other factors that might determine their shopping behavior.  Taking all this into consideration will help you determine if you are trying to sell to the right type of person.   Companies need to know their market in order to know who they are selling to.  retail insights help with this and give the business owner a better understanding of who they should be marketing too.
This works with things such as paid advertising as well.  If you are a marketer, retail insights are good to follow and understand.  When you are targeting your market on the paid advertising platforms you are looking to target those people that are interested in your products.  By narrowing your marketing down, you save money but also have a better ROI or return on investment.  This allows the company that you are marketing to do what they do best and that is to sell their products.  
Use retail insights for better marketing
Retail insights are very useful in marketing and marketing campaigns.  They are a way to judge what is selling and the latest market trends in the area.  If you are an online store, you will gather your market insights a bit differently than brick and mortar stores.  However, the data is basically the same.  What is selling, the hottest trends, and what people are actively seeking are some of the things you want to look at.  Take the time to analyze the data and not just gather it. This can be a large job and doing this on your own might be a bit over your head, especially if you are a retail owner.  You may want to hire a professional that understands how to do this properly.
When retail insights are gathered and analyzed there is a lot of information in there.  Things such as how much people spend on a particular item for example is good retail insight.  Things to look for are what color is more popular and where they are going to purchase these things.  For example, there are a lot of ways to purchase laundry detergent and everyone needs it.  You can purchase it online, at a quick stop, and grab a convenient store or in a large supermarket.  Finding out where the majority of people in your area purchase it, what brand and what that brand packaging looks like are all-important retail insights.
