Thanks for the links
Yes, we do go way back...so let's go back to good old Don Alm and his putting info on floppy disks and giving them a teaser on it and then having to pay for the password to get the rest....
People today are lazy and/or just don't know how to do searches effectively. There is quite a market out there for CD/DVD's with simply links to search findings for a specific niche.
Email marketing to sell the product directly, or if one has resources to do similar to the floppy...rent list of niche market and send CD/DVD free in the mail with sampler on it and then online payment of $10 to get password to rest of the researched links.
If done properly it doesn't take much, or long, to generate a $10,000 payday.
