1- Do not use more index on your table.
2- Drop unused Index .
3- Drop Duplicated index .
4- Create Clustered indexes when necessary .
5- Don’t index every column in a table .
6- primary key constrain is the best than for clustered index in more cases .
7- Order of included column does not matter .
8- use filtered index when well defined subset of results are part of select statement .
