Logos come in all kinds of shapes and sizes however they typically are one of 5 different classifications. Designing a logo is about much more than an exercise in aesthetic. A logo must be a positive depiction of the product or service it represents. When designing a logo, knowing which type of mark would be the most appropriate for the application will help you achieve a stronger solution.
Wordmarks
A wordmark is a logo comprised of text only featuring a unique typographical treatment used to convey the brand’s message or positioning.

Letterform Marks
Letterform marks use one or more letterforms as a symbol to convey the brand message.

Marks
A mark is a literal and often pictorial representation of a company or product. The image is usually a reference to the company or a brand attribute.

Abstract Marks / Symbols
Abstract marks and symbols use visual form to convey a concept that is relevant to the brand message.

Emblems
Emblems are a complex mixture of pictorial elements and type that are linked to the organization and its positioning.

Each of these different classifications of marks has its own design challenges and clichés. Using these marks effectively is a combination of experience and research. For more great examples of logo design be sure to check out faveup.com (where I collected these examples).

Logo work is not at all my strong suit. I can manage but I’m not to good at it.

David,
I have not been doing any identity work for a while, however it is my favorite type of design. Nothing else you can design has as much impact on a business or product than it’s identity.
This post was part of me making sure that I do not loose touch with the practice. Once again, thanks for the comment!

Nice post, and thank you for using my logo as an example as well

Sure thing Joram, it is a solid concept

Nice post!
I’ve never heard logos discussed in this way before.
I’ve been trying to come up with a logo for myself, my blog and photoblog. Without much success so far, my sketches haven’t grabbed me… but I’ll keep at it.

Great post! You have classified logo in a very interesting way. I like that. Good job

Zinni, thanks for this. If it interests you, I think it would be helpful for others to hear what the strengths are of these different types of marks. When watching companies develop an identity, I’ve found the process is often to follow the direction most apparent to the mind of the designer — but that may not be the best direction. I bet these have different strengths that could be better exploited consciously. What is your experience on this?

Ben I believe you are correct. There are certain types of marks that have typically met the needs of certain types of industries. For example it is very common to see restaurants effectively use an emblem. This was my original idea, however it was too long for one post. Hint: I may be breaking these up into a series of articles

I love your helpful breakdown of logos. One minor question. Could you include more recognizable and international logos in your future discussions? i.e. IBM, Google, Starbucks, Nike, VW, et al.

So a logotype is now called a wordmark and an icon is now called a mark?

Very good article. Thanks a lot.

The Fondant logo suggest that there’s probably a sixth category: coffee stains … Lucent … Morning Joe on MSNBC …

Well done! Keep up the good work.
BTW, if you have a moment, I’d like your opinion on my blog listed above?

I’m 100% agree with your blog idea. But main thing is what ever you design should be creative to handle the company brand.
Even its made of Simple lines but should be creatively aligned
