Just like soccer team logos, football logos are focused upon identifying one sports team and setting it apart from the rest. This identity is essential in order to differentiate a team and evoke feelings of loyalty from its fans. The target audience here are the people who follow and support the football team. These are the people who would not just root for a team but also buy merchandise that's emblazoned with its logo.
Since a football logo could be printed on jerseys, banners, and several other items, it needs to be as straightforward as possible. This is also essential in order to convey a serious message of strength, power, and victory to the audience.
The font here should also be versatile and bold enough to be easily read on all merchandise as well as on web pages.
Football logos have to send across the brand message of team spirit and loyalty. To this end, you may want to use a symbol of your football team mascot or something that represents your hometown.
The colors should also be strong, bold ones like red, purple, gold, etc. They colors may also be according to the symbols that you feel would represent your team spirit the most. The tagline could be the team's motto or something related to it, like a motivating quote. A font like Bremen BD BT might be a good fit here.
If you're going for a more generic logo, such as one for a football club or training institute, the main symbol should be something to do with the game itself. This could be a football, a helmet, or a net. No matter what you choose, the design style should remind one of the game so that you don't lose potentials customers or members.
If you want to have the most effective football logo, consulting a professional logo designerwould be a sound investment. You'll have the benefit of their experience and expertise in this field and be able to enhance your sales with the perfect logo.
