Three traps of website profit model design

Anyone who wants to make a gold rush on the internet knows how to design a profit model. Of course, the model designed by everyone varies with offline resources and ideas. A lot of people seem to be very nice, but it is difficult to achieve their ambitious goals. The reason is that people unconsciously fall into the trap when designing profit models:
I. Starting from improving the defects of traditional supply models, rather than creating "new demands.
I met two college student friends who made a campus service network. Their niche business was sold to their classmates on the network. As a result, the business started quickly, the balance of income and expenditure was achieved soon (of course, the income scale is not very large ). As a result, they began to expand their business scope and chose second-hand goods and goods transactions between their students. As a result, this service has never improved significantly. These two college students cannot understand why they encounter different businesses.
I explained to them that they always start from improving the defects of traditional supply models rather than creating "new demands" when designing their businesses.
Why? Before having no website, I wanted to buy many students who wanted to eat supper. Because it was inconvenient to go downstairs to the commissary to buy food at night, I gave up buying (if needed, but not realized ). Now, the websites of two college students provide the overnight service, which may not have been consumed. Now the demand has become a reality.
However, the transaction for second-hand goods is different. If you want to trade second-hand goods before you have a website, you need to appear in some places in the school before you can trade second-hand goods. Because the school circle is small, many people who have the idea to conduct second-hand goods transactions, many of whom have low expectations for the possibility of reaching a transaction, this led to the cancellation of second-hand goods transactions on offline campuses (weak demand ). Now, with the website, the information asymmetry between the two sides of the second-hand goods transaction is reduced. However, there are two restrictions on offline transactions (one is that the limited amount of information leads to a reduction in the possibility of transactions, and the other is that the possibility of direct transactions between the two parties is far weaker than that of indirect transactions between the three parties ), in the initial stage of online transactions (when the transaction information is not rich enough), the second restriction cannot be solved even if the information of second-hand goods on the Internet is sufficient. At this time, we can find that the demand for online second-hand goods transaction is still relatively weak (and we have not really created a "new demand"), but only improved the information asymmetry between buyers and sellers.
From the above case, it is easy for people to fall into the simple profit model design idea of "current supply mode defect + network advantage. This idea is not completely undesirable (the success of the overnight business is an example), because the current supply model defects can be completely compensated by the network advantages, therefore, the profit model design will be fine (such as the overnight business). However, if the network advantages cannot completely compensate for the supply model defects, then there will be major defects in the profit model design (such as the second-hand goods and goods trading business ).
Therefore, there will be problems simply starting from the "current supply model defect + network advantage" to design a profit model.
