Question 2: How can clothing store employees improve the turnover rate of clothes? First, timely induce and use the trading signals disclosed by customers. In the process of communication, clothing shopping guide pays attention to customers' every move, observes whether customers' language, behavior or emotions reveal their purchase intention or information, and makes the most correct judgment in time according to the changes of customers' speaking style, facial expressions and gestures.
Second, create an environment for negotiating with customers alone. Generally speaking, it is easier to make a deal when communicating with customers alone. A beautiful and closed environment can reduce the psychological pressure of customers. In such an environment, customers are more likely to let go, which is conducive to the enhancement of self-confidence. At the same time, the quiet atmosphere will also promote the emotional communication between sales staff and customers. In order to successfully promote clothing, clothing guides must find ways to create an environment for separate negotiations.
Third, cultivate trading methods. At the last critical moment of clothing sales, the clothing shopping guide must control the way of speaking, articulate, persuasive and confident. The attitude of clothing shopping guide in sales transactions should be approachable, natural and graceful, so that customers can relax and have no scruples, and the probability of natural transactions will be higher.
Fourth, make decisions in stages. In the final stage of promotion, clothing guides should not force customers to make a purchase decision immediately. Before the customer makes a purchase decision, the clothing guide should ask the customer some questions step by step, so that the customer can analyze the various components of the transaction and then make a decision.
Fifth, there is a certain trading space. In the process of promotion, the shopping guide should pay attention to leaving room in the transaction, so as to become the last weapon at the critical moment and urge customers to make a purchase decision. At the same time, we should also leave some room for customers to buy, so as to continue to promote the transaction of clothing.
Question 3: How can the clothing shopping guide treat customers to improve the transaction rate? I can't understand the psychology of the guests, that is, get twice the result with half the effort, and the guests won't follow you anyway. China Clothing Management Network believes that the role of salesmen is incomparable in learning to sell and improving the sales performance of stores. Whether a salesman can master the skills of clothing sales is very important. First of all, pay attention to the skills of recommending purchases. In addition to showing and explaining clothes to customers, shop assistants should also recommend clothes to customers to arouse their interest in buying. You can recommend clothes in the following ways: clothing sales skills 1. Be confident when recommending clothes. When recommending clothes to customers, salespeople must have confidence in themselves, so that customers will have trust in clothes. Clothing sales skills 2, suitable for customer recommendation. When presenting goods and explaining them to customers, we should recommend suitable clothes according to the actual objective conditions of customers. Clothing sales skills III. Use gestures to recommend to customers. Clothing sales skills 4, with commodity characteristics. Every kind of clothing has different characteristics, such as function, design, quality and so on. When recommending clothes to customers, we should emphasize the different characteristics of clothes. Clothing sales skills 5, around the topic of goods. When recommending clothes to customers, we should try our best to lead the topic to clothes, and pay attention to customers' reaction to clothes, so as to promote sales in time. Clothing sales skills 6. Tell the advantages of all kinds of clothes accurately. When explaining and recommending clothes to customers, we should compare the differences of various clothes and accurately tell the advantages of various clothes. In addition to the above-mentioned clothing sales skills, we should also pay attention to the key sales skills. Focusing on sales means being targeted. The design, function, quality, price and other factors of clothing should be suitable for people, so as to truly make the customer's psychology transition from "comparison" to "belief" and finally sell successfully. It is a very important link in sales to make customers have the belief of buying in a very short time. Focus on sales has the following principles: clothing sales skill principle 1, starting from 4W. Making suggestions on when to wear, where to wear, who to wear, why to wear, etc., is conducive to sales success. Principles of clothing sales skills II. Keep the main points short. When explaining the characteristics of clothing to customers, the language should be concise and clear, and the content should be easy to understand. The most important characteristics of clothing products should be stated first, and then spread out layer by layer if you have time. Principles of clothing sales skills III. Specific performance. According to the customer's situation, improvise, don't be stereotyped, just say "this dress is good" and "this dress suits you best" and other simplified and generalized marketing languages. Change the way of speaking according to the sales target. Introduce different content to different customers to suit everyone. Principles of clothing sales skills iv. Salespeople should grasp the trend of fashion, understand the pioneers of fashion, and explain to customers that clothing conforms to the trend of fashion. Well, I've told a lot of the truth. Next, China Clothing Management Network will analyze the typical psychology of some guests spending here. What can you add to make our terminal service better and better? First, guests buy six psychological stages 1, and observe and browse two kinds of guests: the destination guests quickly enter the store, go straight to the subject, and come straight to the point and ask about their favorite clothes; There is a purpose to buy a commodity, but the specific color and style of clothes are not very clear. Idle guests have no clear purpose to buy clothes they are interested in. They will kill time, go shopping and admire all kinds of clothes. 2. attract attention. Guests find the clothes they are looking for, or the style and color of a certain dress attract guests. 3. Induce Lenovo to associate the feeling of wearing this dress on yourself, and immediately feel excited. "I will wear this skirt to the company tomorrow, and my colleagues will definitely praise me. That's great. I have to try! " It is important for guests to associate clothes with life. Decide whether she will take further action. When a guest is interested in one of our clothes, we show it to her. Touching and so on is the best way to make her think better and more! 4. With a good association of desires, there will be a desire for possession. On the contrary, it is often. We can successfully encourage her to try it on, which is the best way to stimulate her possessiveness. 5. Contrastive evaluation produces possessive desire, which does not mean immediate purchase behavior. Guests will compare similar clothes of different brands with experience and knowledge, and think about and analyze their personal needs and the style, color, quality and price of clothes. Thinking and analysis are not necessarily rational, but may also be irrational. At this stage, our clothing sales ... >>
Question 4: How to retain customers and improve the transaction rate when there is little passenger flow in shopping malls? A veteran in the clothing industry once said: "Passenger flow and product structure are two basic factors to ensure sales. Without either of these two factors, the sales volume is absolutely zero. " Of course, this is a bit absolute, but it can also be seen that for clothing brands, the direct impact of store passenger flow and product structure on sales volume is great. In order to effectively improve the profits of unit customers and realize customers' repeated purchase, cross-purchase and recommended purchase, we must start from the following five aspects: First, strengthen the active service consciousness of service personnel, establish the concept of customer first, make every customer who comes to the mall feel at home, and make the mall form a good reputation among customers, thus improving the repeated purchase rate and recommended purchase rate of customers. The second is to carry out service and sales skills training, improve service level, quickly respond to and discover customer needs, recommend appropriate products to customers in a targeted and timely manner, improve sales hit rate, win customer trust, and thus increase the repeat purchase rate of customers. Thirdly, readjust the layout of merchandise display and shopping malls, find out the goods that may realize cross-selling by observing customers' shopping habits and analyzing the previous sales data, and arrange these goods in the same shopping area to facilitate customers' purchase, thus improving the probability of cross-buying. For example, put basketball clothes and basketball, wrist guards and basketball shoes in one place, and so on. Fourthly, based on the principle of "retaining old customers and attracting new customers", we should formulate more reasonable and effective marketing strategies and customer loyalty programs, thus greatly increasing the purchase rate of customers. For example, the implementation of the "points reward" policy, the establishment of a "member club", the monthly selection of VIP members, members' birthdays to send gifts, or send text messages to congratulate. Fifth, the performance appraisal and reward of service personnel should be linked to their service level and service attitude, so as to arouse the conscious service consciousness of each service personnel. Grasping every customer is the most direct way to solve the problem of less passenger flow, and merchants are the most direct executors to avoid the impact of less passenger flow on sales. Therefore, to strengthen the professional quality of business, on the one hand, it is to strengthen the training and assessment of business sales skills and product knowledge, improve the personal quality and sales ability of business, and increase the turnover rate of sales; On the other hand, it is to strengthen communication with merchants, understand their real thoughts and improve their loyalty to the store. When the passenger flow is relatively small, the business mentality is easy to be impatient. If we don't know their real thoughts and thoughts in time and in detail, we can't solve their doubts, and blindly demanding performance for business will easily lead to the loss of store operators. On the other hand, the emotional irritability of business personnel will directly affect their mental outlook and sales skills when shopping guide. As a business supervisor or regional supervisor, it is necessary to communicate with the business frequently, understand their status in work and life, and understand some things that bother them, so that they can release their inner pressure and avoid personal emotions of the business from affecting the consumption of limited customers. In addition, as a store manager, you can enliven the store atmosphere and change the status of business people when the passenger flow is low through games or exhibition games. Really seize every customer and improve our sales.
Question 5: How to improve the performance of shopping guides? 1. Very familiar with the goods in the store: 1. Remember the article number and price of more than 70% goods. 2.ABC commodity classification is clear at a glance. 3. I am very clear about the personality characteristics of the basic styles, mainly keeping in mind: men's fat leg style, women's trousers with higher waist and larger legs (general styles need not be remembered). 6. A shopping guide's familiarity with goods often determines your turnover rate. As long as you improve your familiarity with goods, you can at least improve your personal performance by more than 10%. 2. Improve personal on-site processing ability: 1. Proficiently master and use 20 sales language skills of Ceng Zhi cowboys. When trying on pants, customers should not wait outside the fitting room, but should consider that if customers don't like this one, they should push the next one. 4. When customers are not satisfied after trying on pants, they should communicate with customers, find out the reasons and immediately judge which style to recommend. The pace of doing business must be fast. Many businesses can't be closed because the pace is too slow and customers have new questions. 6. To do a good job in joint sales, after the first transaction, we should look for opportunities for customers to try on another style, because an excellent shopping guide often has 30% or even more performance from joint sales, and the performance generated by joint sales often exceeds the performance of the first transaction. (Because after the first transaction, it will often win the trust of customers, and it is much easier to recommend styles than the first transaction). 3. Strengthen teamwork: 1. Your deal will often prompt your teammates to close the next business soon. If AB two shopping guides are doing business with different customers at the same time, if A shopping guide's customers are very picky, often B shopping guide's customers will become difficult to deal with. Therefore, the shopping guide should be adjusted according to different situations. 2. When a shopping guide completes a transaction and the customer chooses another product when changing the trouser leg, B shopping guide should immediately help A shopping guide to change the trouser leg, because A shopping guide has won the trust of the customer in the first successful transaction, and it is easier to understand the customer's needs and conduct joint sales.
Question 6: How to improve the turnover rate of clothing sales is a challenging job, and how to improve the turnover rate is even more a knowledge. Try it yourself.
Question 7: The old salesman taught me how to improve the sales turnover rate. Description: Salespeople are always thinking about how to improve sales turnover, but they are always puzzled. How to improve the sales turnover rate depends not only on how many skills you have mastered, but also on whether you have mastered the psychology of customers and whether you can find ways to meet their needs and potential needs! Let's see how the old sales bird improves the sales turnover rate! Teacher Zhang Yi thinks; The key to the success of the transaction is to sign the bill, and the things behind the agreement will be logical. For example; The down payment for buying a house has been given and the agreement has been signed. If you want to break the contract, you will pay the price. How to release the single energy next; Teacher Zhang Yi shared several steps with you. The first is to place an order by force, which is the most important link in the whole business process. If the order is forced to fail, your whole business will fail. In fact, the whole business process is a forced process. It is necessary to master the skills, neither too fast nor too slow. You should relax, step by step, be rational and emotional. Let's discuss the way to place an order by force. 1, think about a question, why hasn't the customer signed the bill with you yet? What is the reason? Many colleagues have suggested that customers always procrastinate. I don't think the customer is dragging, but you are dragging, and you don't change. Always waiting for customers to change, is it possible? Business never emphasizes objective reasons. The client didn't sign the bill. There must be something you didn't do. Think about it? This is a matter of mentality! 2. Know the customer clearly and understand the current situation of the customer. What is holding you back? You should firmly believe that every client will cooperate with you sooner or later. It's only a matter of time. All we have to do is advance the time and then advance it. Reasons: lack of awareness, no plan, poor sales, just acting as an agent, building a new factory or moving, being restructured, single variety, limited customers, too busy, too expensive, not knowing you or CE, not trusting you, not having a computer, not being managed, and so on. I'm not afraid. I'm going to worship Buddha and kill ghosts. 3, as long as the idea does not decline, the method is always more difficult than it is. Don't panic, don't mess, keep a clear head and clear thinking. From ruin, justice is awesome. We should analyze problems and solve them. It is normal to have problems. Great! I just like challenges. Is it interesting? Life is full of fun, just like a game. 4. Grasp the customer's psychology, think what the customer thinks and worry about the customer's urgency. You need to know what he is thinking and worried about. What concerns does he have? Everything is under control, and you are the director. You must have a positive attitude, such as being too busy? Why? This is because some things can be done on the Internet, but you just run errands and send a Yi Meier! How do you guide customers to turn disadvantages into advantages and disadvantages into advantages? 6. Solve problems for customers, help customers do something, be serious and responsible for customers, do practical things for customers, and let customers feel the service and warmth of ce. 7. Conquer customers and carry forward the spirit of leeches sucking blood. This spirit is not only reflected in working hours, but also in spare time. You must be patient, persistent and indomitable. With your persistence, you will touch customers and make God cry and say, Alas, young man, I really admire you. Your spirit is worth learning from our business people. Come and talk to * *! I was hired with a high salary. 8. If it can be solved, it will be solved. If you can't solve it, avoid it, and the problem will be diluted and avoided. This requires that your thinking must be flexible. 9. Suppose that the transaction method is one of the common methods we use to make orders. Let him join our membership service first, take photos for him first, and so on. Signing the bill is a very smooth thing. Or fill in the form before signing the bill, and wait until the conversation is almost over: let's go through the formalities and don't say anything too harsh. 10, the forced order is semi-push, that is, the forced transaction method, which has the potential to swallow mountains and rivers and grab customers. Let customers feel that there is an irresistible force. 165438+ means to be natural and graceful, eloquent and just right. You can't use more delicious food. Lay a good foundation for future work. 12, draw a pie, let the customer think about the various benefits brought by the network, let him daydream and make his dream come true. 1......& gt& gt

Question 10: How can we improve the turnover rate of Taobao shops? 5 points Taobao shop promotion strategy
The specific promotion strategy of Taobao online store can be started from two aspects: inside and outside the online store, in which the sales promotion in the online store is mainly free of postage, discount and gift. At the same time, due to the particularity of online shopping and online stores, its unique online store credit management can not be ignored. The promotion outside the online store mainly adopts a "three-pronged approach" to ensure the ranking of search engine results, compete with online store sales alliances, post and reply in Taobao communities and forums, and effectively use advertising recommendation positions and Taobao Want Want.
In recent years, although the number of online stores is increasing day by day, many online stores are just a flash in the pan due to lack of management awareness. Online stores, like traditional stores, need the careful care of the owner. Therefore, it is necessary to formulate a promotion strategy that is suitable for both online stores and network environment.
Online stores are divided into two types according to their existing forms: one is independent online stores; One is an online shop registered in a large professional website, that is, according to the corresponding regulations, a member is registered in a large professional website that provides online shop services, and the right to use and operate the online shop is obtained. At present, this is the main way to open a shop online. This paper takes the online shop registered on Taobao as the research object, and makes effective promotion strategies from both internal and external aspects according to its characteristics.
First, the promotion strategy within the online store.
According to the characteristics of Taobao shop, the internal promotion strategy of online shop focuses on sales promotion and credit management.
1. Promotion
In-store sales promotion methods avoid postage, discounts and gifts, and the rest are supplemented.
1) Free postage. Postage in the intermediate link of online shopping has always been one of the focuses of buyers, which will affect buyers' perception of online shopping price concessions. At present, postage is mainly divided into: post office (parcel surface mail), logistics express, express mail and so on. The price of surface mail is lower, but the cycle is longer; The price of logistics express is moderate, and the delivery cycle is 3 ~ 5 days; Express mail is expensive; Therefore, the courier company is the most accepted by buyers. Shopkeepers can reduce the postage according to the number of goods purchased by buyers, so that consumers can feel at home psychologically and do not need additional fees.
(2) discount. Because discount promotion directly benefits consumers and makes customers feel the benefits directly, it is the most commonly used phased promotion method at present. Discount mainly takes the following two ways: First, irregular discount. On important festivals, such as Spring Festival, Valentine's Day, Mother's Day, Christmas and so on. , will give 20- 10% discount, because people tend to have more buying potential and impulse during festivals. Shops should choose products with large price adjustment space to participate in activities, and don't generalize. The advantage of this method is that it meets the needs of festivals and will attract more people to buy. Although discounts may lead to a decline in profits, sales will increase and total sales revenue will not decrease. At the same time, it will increase the visibility of the store and have more customers, which will also promote future sales. The second is a discount in disguise. If "bundled" sales are adopted, they will be sold in the form of gift boxes on holidays. The advantages of this method are: it conforms to the festive atmosphere and is more humane.
(3) gifts. The key to gift promotion lies in the choice of gifts. Appropriate gifts will play a positive role in promoting product sales, while choosing inappropriate gifts can only increase costs, reduce profits and make customers dissatisfied. When choosing the right gift, we should pay attention to the following points: first, don't choose defective or inferior products, which will only backfire and affect the reputation of the store; Second, choose suitable products or services that can attract buyers. You can give samples or samples, or you can give intangible things-services. Third, pay attention to the budget of gifts. Gifts should be within an acceptable budget, and the cost should not be increased because of too many gifts.
(4) membership and points. All customers who have bought goods in this online shop become members of this online shop. Members can not only enjoy shopping discounts, but also accumulate points and exchange goods for free. The advantage of this method is that it can attract buyers to come to the store again, introduce new buyers to the store, consolidate old customers, get more discounts, and expand the exploration of potential buyers.
(5) red envelopes. Red envelopes are special promotional props for Taobao. Sellers can flexibly formulate the rules for giving and using red envelopes according to the different situations of their stores. In this way, the popularity in the store can be improved. Because the red envelope has a time limit, it can prompt customers to buy it again in a short time, effectively improving the network ... >>
