1. The fastest earner does not mean it's the fastest paying. I've never been paid by a program with a minimum link above 3-cents. Generally, it's best to stick to sites with minimum links up to 1-cent. 2. Study the advertising prices. If you can't understand how the site is making a profit, it's a site best to avoid. 3. Beware of NPA (New Program Announcement), search for the site with a track record for paying. 4. Study the black lists. Visit forums such as www.getpaidforum.com. 5. Avoid sites that force searches. 6. Be careful of WMs that own several sites. The losses can be high if the WM decides to close. 7. Diversify. Invest your time in several programs from different owners. That way no one program can make or break your business.
