Can you name a few of the best classified sites that helped you...besides the obvious?

ebay is an auction site, not a classified site. Adlandpro has the highest volume of traffic compared to all the other sites mentioned thus far - except craigslist of course which is scores above the rest. But as most know its not always about traffic volume - only conversion matters.

OLX, quicker, ebay are the most popular classified sites.

I use a list of them. In order to get results, you should allocate at least 15 minutes a day and make FREE Posting.
There are very known classifieds and very new!

webcosmo.com gave me the best results

I prefer olx is the best Indian classified website. Do Any one know any best networking site in classified.. ?

My best result i get from ablewise.com

Mike G i know one that is great but you will need a premium membership (10$ a month). All ads are renewed automatically. I have generated multiple sales over there. Consistence is the key, you should post at least 5 ads a day & do it for months i am very confident that it has the power to help people grow their business and make sales. Featured ad price are very low and very effective.

adlandpro is great if you know how to use it.

The only classified site I have had positive results with is Craigslist, but I guess that's one of the obvious ones.
