A new website, PostShareSell.com, has taken a different approach to online classified advertising. Its integration with multiple social media sites is designed to make any ad posted on it go viral. If the online community was to embrace this site in the same way it has embraced sites like Facebook (News - Alert) and Twitter, online classified advertising would be changed forever.

PostShareSell.com is a DBA created by Tampa, Fla.-based B2B e Trader LLC. One of the people associated with the company is Jovan Haye, who played for the Carolina Panthers, Tennessee Titans and Tampa Bay Buccaneers of the National Football League. Past promotions offering free game tickets suggests that the company benefits from Haye’s relationships with his former teams. Another promotion includes a $100 weekly prize to the site user who creates the most viral listing.

The site could be described as a combination of Craigslist, Facebook and Hootsuite. Users can sign-up manually or through one of several social media accounts. Goods and services can be sold through the site and transactions can occur between business and non-business users. Listings appear on PostBuySell.com and the seller’s various social media account feeds. Social media features that let a seller’s friends give feedback are what make it possible for the listing to go viral.

If the ad listing, for example, appears on the seller’s Facebook news feed, that person’s friends have the option to ‘like’ the post. Once that happens, the seller’s friends and even friends of friends will see the listing on their news feeds.

As one testimonial on PostShareSell.com states, this has much more potential than Craigslist. Instead of having chronologically-ordered ads that get bumped into obscurity and have to be reposted frequently, an ad gets posted once on PostShareSell.com and has the ability to spread to a wider audience. It’s like the adage of you telling two friends and them telling two friends and so on.

One thing that’s not immediately clear is how PostShareSell.com makes its money. A look at the terms and conditions of the website suggests that promotions sent to the site’s registered users might be one way. There is a lot of wiggle room in these conditions that allows the company to change them at any time, much like Facebook does.

Assuming that the company has a profitable business model, if its approach catches on with users, the effects would be revolutionary. The ability to reach so many users that quickly could make this type of advertising reach as many users as broadcast ads do, but because of features that allow ‘liking’ an ad, the audience is likely to be a more targeted one.
