Each member makes available slightly more ad space than they use themselves, with the exchange selling the excess inventory for a small fee to other advertisers. That's how the exchanges make enough money to cover their operating expenses. There's no minimum or maximum size for participating sites, so everybody from big corporate sites to personal home pages can get involved. Since so many sites belong to Link Exchange, it's a good bet that you'll find the ones you want to trade with through them. Exchanges are free to join and use, making them a risk-free and sensible way to go.
