A listing only costs $5. As you can imagine, this has led many to suggest that they are trying to target the Fiverr crowd. Fiverr undoubtedly has a better set up, though Flippa has the potential to be better due to its targeted user base of website owners. Links have nofollow tags attached to them too, which should hopefully avoid the classifieds becoming nothing more than a link farm.
I like the fact that your existing Flippa profile is used in the classifieds section. This gives a bit of legitimacy to listings and those who have a good rating on Flippa could capitalise on this. What is unclear is how much traffic the classifieds section is generating. I would love to know how much traffic the average listing gets.
There are not too many listings just now, though the classifieds are linked in the main menu so I believe we will see more listings over time. i recommend checking it out.
