Matching refer respectively to term and keyword correlation values reach 80% and 50% after can trigger showing advertisement；Accordingly
, if current matching range is the wide in range matching in the second level, after needing to reduce matching range, then matching range can be repaiied
It is changed to the matching of the first level width.
Further, it when reducing matching range, can reduce step by step, for example wide in range matching is revised as first from the second level
The wide in range matching of grade, alternatively, multiple ranks can also be reduced, for example wide in range matching is revised as accurate general matching from the second level, specifically
It can be set according to application demand.
In the present embodiment, by determining user to be controlled according to budget depletion rate, it can find to need what is controlled in time
User avoids the budget of user from comparatively fast ruing out of, and then extends the online hours of the promotion message of user；By according to triggering matter
Numerical quantity determines keyword to be controlled and reduces the matching range of keyword to be controlled, since the smaller cost of usual matching range is got over
Low, so as to reduce the cost needed for keyword to be controlled, and then it is higher the cost under saving can be triggered quality
Keyword, and higher flow is brought by the higher keyword of triggering quality, so as to ensure user under certain budget
Obtain more flows.The present embodiment is by determining user to be controlled and keyword to be controlled and reducing keyword to be controlled
