Data collection is difficult (too much and a lot of useless)
The data processing is chaotic (I don't know who should use a lot of data)
The biggest difficulty is the small customer demand. Many companies (with high profits) are looking for professional consulting companies, because they are doctors, and they can provide almost all the analysis results from the overall strategy to the detailed operation, and they know the actual situation of the client company's industry (this is their daily work). The website relies on copying, modifying, editing and pasting (this is a fact) and has no core competitiveness. What they can do is to increase the click-through rate and earn advertising fees.
For example, information websites are like medical books, and patients have to study by themselves. Professional consulting companies are like doctors, specializing in diagnosing diseases and prescribing drugs.
Please ask Baidu to consult a professional consulting company, and the click-through rate of the portal website will not be mentioned.
