It doesn't mean anything. It may put you in their talent pool, but it doesn't mean that you are suitable for this company at present. They are building a talent pool, and if there is a vacancy, they will consider informing you to go for an interview. Personnel recruitment may look at the situation of reserve talents from time to time, so the number of visits is also counted. If they haven't informed you, keep looking for other opportunities. Browsing doesn't mean anything. Informing you is what really needs you.
