JD.COM weighting and weight reduction factor, weighting factor: 1. Officials say that short titles have high weight, JD.COM titles are optimized, and 90 words (45 Chinese characters) should be used well, but remember not to pile up keywords. 2. Each JD.COM SKU product can upload 6 pictures, yes, yes! Upload all six pictures! The more regular the main graph is, the more weighty it is. 3. Evaluate and print bills. There are also sales in JD.COM, which can be viewed on the mobile side. The quantity of evaluation is very important. The more evaluations, the higher the cumulative weight value. In addition to printing bills, friends can achieve the effect of printing bills in the following two ways: printing bills to charge the phone bill 2. Manually control business class sales! This is the same as Taobao. Looking up the store operation data for three months, I summed up a formula (male bag category) 1 business class sales =2 search traffic+1 category traffic; 1 Taobao training sales =0.5 search traffic. If your natural traffic conversion is ideal, then control the business class and put it in hard! 4. gifts! JD.COM must have a gift. This is a common problem, because I found that there are gifts before 10 in our category. Therefore, if people have you, you will be knocked down by others. So, if you can, match it with a gift! 5. Cash on delivery! JD.COM's greatest advantage is that he lost to others at the starting line if he didn't open it. 6. All kinds of customer service, such as Taobao, freight insurance, charity donation, seven days no reason to return. Open if you can. 7. Good score! If it is 93% lower, there is no chance to participate in activities. Therefore, the product must pass the customs, and if it does not pass the customs, it will pass the customs. 8. Store dynamic rating! This influence is the biggest, which will affect the ranking weight of your whole store. 9. Fill in the category correctly! This is the same as Taobao. In JD.COM, in the later period of products, the main traffic source of explosions is category traffic. If the category is not filled in correctly, the flow is not accurate enough. So you must fill in the category correctly at 10. The price in JD.COM determines your selling index. Within a reasonable range, if the price of JD.COM is set higher, it will hit the hot-selling commodity list of 1 1. As long as the normal sales of goods are controlled within 10000, there is also a tendency to weigh 12. Five data of e-commerce products: natural traffic click rate, conversion rate, jump rate, page stay time, visit depth 13. Non-newly developed products belong to the new product period within 30 days and have a certain search weight 14. You can skillfully use keyword sorting to transition the growth cycle of products) 15. Commodity plus attention, same weight, attention = set power reduction factor: 1. Being caught swiping a bill, making false transactions, deducting points, imposing fines, demoting rights, and restricting participation in marketing activities II. Work order reply rate, after the work order is overtime, deduct 1 minute, and the reply rate is lower than the minimum limit of the rules. Reduce the weight of the whole store (before implementing the regulations) 3. It is inappropriate to suddenly add SKU to sell products. Don't make such low-level mistakes again. 4. Modifying the main map will temporarily reduce the weight, and the weight will return to normal after the search engine grabs the new baby main map. 5.JD.COM does not have the 7-day off-shelf optimization like Taobao, and the products are frequently put on the shelves, but the products will be degraded. 6. Delayed delivery, JD.COM pays attention to buyer's experience.
What do you mean by weighting? "Weight" is a mathematical concept. Explain this word separately first. "Add" means "multiply". The popular understanding of "weight" is "coefficient", and this coefficient is called "weight". So "weighting" means "multiplying by weight", which means "multiplying by coefficient". In mathematics, there are two calculation methods, namely "weighted average" and "additive average". When the "weights" are the same, the calculated values of the added average and the weighted average are the same. Because the "weights" are different in some cases, the calculation of additive average can't reflect the true and reasonable average, so we generally use weighted average at this time. For example:
1. Calculation under the condition of known weights: Your test scores in one academic year are: 30% in the mid-term exam, 50% in the final exam, and 20% in the homework. (These percentages are known weights and proportions of each period) Find the average grade of three semesters.
If you get 84 points in the mid-term exam, 92 points in the final exam, and 9 1 point in the homework exam, it is (84+92+9 1)/3=89 points.
Then the weighted average method is: 84 * 30%+92 * 50%+91* 20% = 89.4, which means that the weights are 30%, 50% and 20% when the weights are known.
Second, in the case of unknown weight?
If you participate in the competition, calculate the average score: a group of 50 people will give you 80 points; There are 60 people in the second group, and you get 82 points. On average, your score is (80+82)/2=8 1 minute. The weighted average is (50 * 80+60 * 82)/(50+60) = 81.09, which is reasonable.
To understand the meaning of weighting, we need to understand the meaning of "weight" first. The ancient meaning of "weight" is weight, which is an iron knot that can slide on the scale to observe the quality. "Mencius Hui Liang Wang Shangshang" said: "Powerful people know the weight." That's what it means. For example, when the school calculates the final grade, the mid-term exam accounts for 30%, the final exam accounts for 50%, and the homework accounts for 20%. If someone takes a midterm exam of 84 and a final exam of 92, the homework score is 9 1, and if it is an arithmetic average, it is (84+92+91)/3 = 89; Then the weighted value is 84 * 30%+92 * 50%+91* 20% = 89.4, which is when the weight is known; According to statistics, when calculating the average and other indicators in statistics, the values that weigh the values of various variables are called weights. Let's take an example and find the average of the following series of numbers 3, 4, 3, 3, 2, 4, 4, 3, 3. The general solution is (3+4+3+3+2+4+4+3+3+3+). This method used to be called the weighting method.
What do you mean by weighting? According to statistics, when calculating the average value and other indicators in statistics, the value that weights the values of each variable is called weight.
For example.
Average the following series of numbers.
3、4、3、3、3、2、4、4、3、3、
The general solution is (3+4+3+3+2+4+4+3+3)/10 = 3.2.
The weighted solution is (6 * 3+3 * 4+2)/ 10 = 3.2.
Among them, 3 appears 6 times, 4 appears 2 times, and 2 appears 1 time. 6,2 and 1 are called weights. This method is called weighting method.
Generally speaking, the average is to add up all the numbers and divide them by the total. Expressed as:
(p 1+p2+p3+.....+pn)/n；
However, there are some identical data in some data records. When calculating, if there are several identical numbers in that number, multiply this number by several. This number is called weight and weighting, which is multiplied by several and then added. The average is still divided by the total.
Or take the above figures as an example:
Each of them has some same numbers, which are respectively expressed as: K 1, K2, K3...KN；;
The formula of weighted average is: (k1p1+K2P2+K3P3+... KNPN)/(k1+K2+K3+... KN).
What do you mean by weighting? When calculating the average, there is a difference between arithmetic average and weighted average. The former ratio is 1, while the latter ratio is different.

What is power? What do you mean by weighting? To understand the meaning of weighting, we need to understand the meaning of "weight" first. The ancient meaning of "weight" is weight, which is an iron knot that can slide on the scale to observe the quality. "Mencius Hui Liang Wang Shangshang" said: "Powerful people know the weight." That's what it means.
For example, when the school calculates the final grade, the mid-term exam accounts for 30%, the final exam accounts for 50%, and the homework accounts for 20%. If someone takes a midterm exam of 84 and a final exam of 92, the homework score is 9 1, and if it is an arithmetic average, it is (84+92+91)/3 = 89;
After weighting, it is 84 * 30%+92 * 50%+91* 20% = 89.4 when the weight is known;
What if the weight is unknown? I want to know the chemical weighted average of two classes. There are 50 students in class one, with an average of 80, and 60 students in class two, with an average of 82. The arithmetic average is (80+82)/2=8 1, and the weighted average is (50 * 80+60 * 82)/(50+60) = 865438+. Full score 10, 8 for experts, 6 for teachers and 7 for students, but you think the weight of experts and teachers and students should be 0.5:0.3:0.2, so the weighted value is 8*0.5+6*0.3+7*0.2=7.2, and the arithmetic average is (8+6+7.

Simply put, it is to calculate the average in proportion.
What does JD.COM mean by authorization? Authorization is the key to organizational operation. It takes people as the object and gives subordinates the necessary power to complete a certain job. That is to say, the supervisor will transfer the decision-making power to his subordinates to deal with employing people, spending money, doing things, negotiating and coordinating, and only grant power, but not entrust the necessary responsibility for completing the work. This is the last word of authorization. Different levels in the organization have different functions and powers, and permissions will flow between different levels, thus creating the problem of authorization. Authorization is one of the important tasks of managers. Effective authorization is an important management skill. If authorized properly, all participants can benefit.
What does lifelong weighting mean? That is to say, no matter where you enjoy the dividend of 1.5% for a long time, for example, if a product has an annualized income of 14%, you will get an annualized income of1.5%.
What does the stock weight mean? There are two places in the stock market where weighting is used.
1, the moving average, that is, several lines in the trend chart, is the average calculated according to historical values; This will not change your value;
2. Weights such as allotment, allotment and dividend, because the total stock plate has become bigger or smaller, in order to ensure your value, you need to weigh it. At this time, although the stock price has become 7.5, you will know that the stock has gone up. It used to be 100 shares, but now it is 106 shares. If you send 10 shares, don't worry about the loss.
The price shown after 3 o'clock in the chart is the closing price of the day, without weighting. But futures are different. The price shown in futures is the weighted price of the day.
