1) Avoid using cursor in Triggers.

2) Avoid executing many sql statements on other tables also.

3) Avoid returning multi-row-resultset or resultset.

4) SET NOCOUNT ON to avoid return of resultset.

And not to forget -
5 )  Specify the order of execution of Triggers (After) in case many triggers present on single table/query action.

6) Triggers runs faster like stored procedures becuase it is compiled into execution plan and keep into memory.
