I am starting a financial company with a friend, does this kind of marketing work? http://www.500-stocks.com/ I've seen a few of these before, but don't know what you really get? It sells itself as a marketing type page, is it good marketing?
The www.linkexperiment.com has had some success, as did www.1000tags.com . If you promote it properly, you may get some sales. It is only worth people buying your links if you have tons of traffic - just the same with any site really. Your traffic must be targeted too. For example, coming from PPC searches with relevant keywords. You might want to remove the free words. They clutter the page and distract people from the links that have already been bought.
