The FIFA Rankings are a system used to rank national football teams based on their performance in international matches. These rankings are updated regularly, typically every month, and take into account the results of matches, the importance of those matches, and the strength of the opponents. The rankings help determine seedings for tournaments and provide a snapshot of a team's standing in the world of football. Higher-ranked teams are often seen as stronger competitors, while lower-ranked teams may face challenges in qualifying for major events like the FIFA World Cup.
