A logo is a unique, distinctive, and recognizable representative of a brand in terms of its visual appearance. It often consists of pictures, symbols, typos, and color schemes based on the brand's style guide. 

A brand’s logo can be redesigned several times throughout the brand’s lifetime to match with people’s tastes and shopping tendencies in the current era. That said, all distinctive features that remind people of the brand itself such as symbols, colors, or lines, will remain unchanged.

Though there is no standard on what a logo should look like, most of the good logo designs in the world satisfy the same three factors as mentioned below:

1. Unique & Distinctive : The logo should be a product of the creative process that is new, modern, appealing, and unique enough to stand out among other competitors.
2. Memorable & Recognizable: The logo should be easy to recognize and remind people of the brand on all platforms/channels it is displayed on. Putting your brand guideline elements into that one icon to make people think of your brand as soon as they see the logo.
3. Simple: The logo should be scalable and aesthetics in every pixel size. Think of the business cards, and the company's other digital or physical merchandise, the logo must be aesthetically pleasing in those places as well.

Although these three rules may sound simple, applying them in actual logo design is not easy at all. That’s the reason why many businesses decided on hiring professional freelance logo design services rather than creating it by themselves. Besides, today’s digital era has enabled us to approach any kind of freelance service in no time all over the world via international e-commerce platforms on the internet. So next time you want to have a logo with the best quality at the most affordable price, you know where to get it from.
