For those who do not know, advertising on classified sites is a great way of promoting a company’s services and products. Not only can it increase website traffic, but usually, this method is also one of the cheapest yet the most effective ways of increasing local sales.  Additionally, many of classified sites are free to use, but you should never try to spam them, because most of those sites are being monitored very closely; spamming will get your account or IP suspended.
Now, when we talk about Classified websites, there are hundreds if not thousands of them out there. Normally, you should not bother of submitting promotional materials to not so popular or low PR websites, because most of them do not have quality traffic. Instead, you should always focus on classified websites that have high quality traffic.
Of course, each country has its own popular classified sites. However, in this article, I am going to mainly focus on Classified sites in the United States (but also includes few classified sites from other countries).

Like most websites, I can’t guarantee they will exist forever. Some of websites might be taken down by the time you are visiting this page. However, most popular sites, such as Craiglist, should be existing for a very long period of time. Like always, if you have any additionally Classified site that you want to add to the list, please feel free to let me know by leaving a comment below.
