All these criteria (there may be many more depending on the business area), you need to choose the most important ones that hit the target. To avoid mistakes, you can ask yourself leading questions: Is age really important in providing this service? Does it matter what your customers' core values are? Does location matter for your particular service industry? Answers to these questions will help segment clients. For example, if the service is provided at home, then it is not so important in which specific area the client lives, which means that this is an incorrectly chosen criterion.
And, let's say, age matters in this case: if you are engaged, for example, in braiding gambling data taiwan phone number bright African braids, the target audience 45+ is definitely not suitable. Even the method of communication with clients can differ significantly depending on the criteria: for people 45+ it is easier to call or order a service on Odnoklassniki, and it is better to communicate with young people in messengers, and attract attention with the help of Instagram and VK. You can also segment customers using CJM (Customer Journey Map).
Before purchasing a product or service, the customer goes through a certain “path”: gets to know the brand/company, shows interest or scrolls through the page, makes a purchase or not, etc. All this helps to divide buyers into groups according to their location on this "path": a regular buyer, a brand advocate, bought the product once, is hesitant to buy or not, or maybe a dissatisfied and offended client. And each group of clients requires its own approach.
