Covert Product Selling Principles

Here are few paragraphs from the book,

Principle 11 – Free E-Zine Subscription
Give people a free subscription to your e-zine. Almost everyone is publishing an e-zine nowadays so it's important to give something extra with the free subscription. You could offer a weekly contest for new subscribers. For example, you could say, "Subscribe And Have A Chance To Win Our Latest Home Study Course!"

Principle 12 – Free Content
Provide your visitors with free content. Your content will be more attractive to your visitors if it's up-to-date or original. You could also offer people the option to reprint the content in their e-zine or web site. If your content is super original, you could use something like "Never Seen Before" in your titles.

Principle 13 – Free Online Directory
Offer a free online directory. The directory could be full of interesting e-books, e-zines, web sites, etc. If people find your directory to be a valuable resource, they will visit it over and over again. You could also put your whole directory into e-book format and allow people to give it away.

Principle 14 – Free E-Book
Give your visitors a free e-book. You could also include your own ad in the e-book and allow other people to give it away. If you don't want to take the time to write one, you could ask other writers’ permission to use their articles. They will just want you to publish their resource box too.
