When we discuss in the design whether a function or element should be added, adhering to the principle of "if there is no need, do not increase the entity", we usually give up functions that only a small/small group of people will use or element, the judgment of this whatsapp Database niche/small group of people will be borrowed from the classic "Mattley's Law", also known as the "28 Law". After the long tail theory was put forward in 2004, it began to be filled with the argument that "the long tail subverts the 28th law". In economics, it was proposed that "as long as the whatsapp Database channels are large enough, the sales of non-mainstream and small-demand commodities can also match the mainstream. to match the sales of goods that are in high demand.
Comparing the long tail theory and the 28 rule, what role can they play in our design guidelines? Let's first take a rough look at what underpins whatsapp Database them: "Long tail" is actually a colloquial expression for the characteristics of Power Laws and Pareto distributions in statistics. Due to cost and efficiency factors, in the past, people could only focus on important people or important things. If a normal distribution curve is used to describe these people whatsapp Database or things, as shown in the figure below, unlike the law of 28, the "tail" in the long-tail theory The role of ” cannot be ignored. The statistical graph of the law of 28 is like an English letter L, 20% is a vertical, narrow and high, 80% is a horizontal, wide and low.
The area of a horizontal is the same as a vertical. Some real data supports this theory, such as Walmart's inventory of low-selling records and whatsapp Database high-selling records are similar; Google currently has about half of its business from small sites; Amazon's total sales of a small number of bestsellers account for about half, and the vast majority of unpopular books the other half; and so on. But it would be a mistake to blindly assume that the unpopular ones are whatsapp Database bound to yield great value.
