Craigslist is obviously one of the most popular websites in the world, and each month it serves millions of users who post and view classified ads on the website. At the time this article was written, Craigslist was ranked as the 28th most-visited English-language website in the world by Alexa. Despite the fact that Craigslist receives such a huge amount of traffic each month, it is also criticized for its design, which seems to be at least 10 years out-of-date.
This very basic design has also become a huge part of Craigslist's branding, and it helps make the website memorable and instantly recognizable. As a result, the company has benefited in some ways from a design that many people consider to be very subpar. Over the years, as various design trends have come and gone, Craigslist has bucked the trends and stubbornly maintained it's bare-boned approach.
However, despite the fact that Craigslist has been able to benefit in some ways from its ultra-basic design, there are plenty of reasons to consider making some changes. A simple approach to design and layout that cuts excess and eliminates anything that is less than critical is typically assumed to improve usability.
