It depends on the needs of the enterprise, the people targeted by different public opinion monitoring tools are different, I don't know what industry you are in? Now the public opinion technology is basically similar, mainly crawlers. However, the sustainability of hardware resources and team is very critical. Now many small companies have just one software, which can't be iterated and updated, and of course there won't be any accumulation, and everyone is fighting a price war. A company's system is good or bad, the key is in the hardware storage and professional team, technology and analysis team. For example, the cost of a company's public opinion costs only 20w a year, you think about a first-tier city of a labor cost is how much a year? So it's not reliable at all. All public opinion products must also have someone to do the auxiliary work. A one-time payment will inevitably lead to risk, I am using the Doritos Public Opinion Data Analysis Station system on a monthly basis
