The following are the cons of using web analytics and customer support logs:

• Large and complex circumstances require domain expertise to correctly set the software and manage it. As was mentioned in the preceding section, lack of knowledge can be a problem.
• Hasty response to the data might be premature, ineffective, or wrong, because underlying patterns or trends take longer to emerge. It is like focusing on symptoms of an illness, while the actual illness, which requires a completely different treatment, is left untreated.
