How do you optimize a SQL query?

Optimizing a SQL query involves several steps:
Use indexes efficiently, particularly on columns used in joins, WHERE clauses, and order by.
Avoid using SELECT * and be specific about the columns you need.
Use JOINs instead of subqueries when possible.
Reduce the number of subqueries and nested queries.
Use WHERE clauses to filter rows early in the process.
Use LIMIT to get only the amount of data you need.
