A creative exercise for you...
Most of these logos are logotypes, that is, where the the design is based on the typography.
If you like, you can make your viewing a creative exercise by considering the business or brand name listed, and before checking to see my design solution, ponder some possible directions that you might have taken in fashioning an appropriate logo.
Most of the designs are for print purposes rather than website logos. Once a vector-based logo is created - that is, one that is scalable to any print size, whether business card, letterhead, road or vehicle signage etc. - it can then be bitmapped (with all sorts of textural, lighting, and image effects) for use on a website. However, special finishing touches will never make up for poor conceptual design.
