You could create a catalogue web site where you send your customers of your initial product. Instead of thinking of your $50 dog training manual as the purpose and end result of your lead building free giveaway campaign, what if you were to think of the sale of the $50 dog training manual as simply being a qualifying purchase so that you can see the person is serious about their dog and is worth promoting your other products and web sites to.

Think about veterinary services. What if you were to create a collection of veterinarians worldwide and refer your customers of your dog training manual to them? Perhaps you could even use google Adsense for that. Create a small script that asks the customer for their city and state, and have the script automatically run an Adsense search adding Â?veterinarianÂ? to the state and city term, and produces a list of local (for them) veterinarians. The customer need not know you are using google until their results come up Â? and then they are more than happy to click through to the veterinarian, thus creating an additional revenue stream for you.

Perhaps you could partner with companies that offer live dog obedience school or dog training classes. Arrange to make these available to your list for a commission.

Of course, this is not about dog training, this is about monetizing your list.

So what is your niche? How many additional products can be added to your offerings that will increase the percentage to which you can monetize your subscribers? How can you use a similar matching technique using google to effectively guarantee that searchers will click through the google results? What are some seminar-type products which you can team up with to earn additional revenue from your list?
