The expression "week by week" refers to something happening or changing gradually over a period of weeks. For example, if someone says "I'm improving my English skills week by week," it means they are getting better at English slowly but steadily as time goes on. This expression can also be used to talk about something that happens or is planned on a weekly basis. For example, "The company's sales are tracked week by week" means that the sales are monitored and recorded every week.
