An effective marketing page is composed of several factors that all work together to create social proof and trust in the product - especially if you're looking to sell a paid Guide.

Let's break down a few of the most successful marketing pages, starting with Nick Eubank's "How To Do Keyword Research For SEO".

Nick's Guide was free for 5 days and he offered it as a reward to his mailing list and blog audience, getting about 100 people into it commenting right away. He then sent and email and made a comment within the guide specifically asking for a rating and review (currently he has 26 reviews and 4.5 star rating - most of them came from those first 100 people).

The main description outlines his personal experience with Keyword research and touches on the main items the guide covers, with a guide explanation of what it is and why it's important to the process.

Finally Nick included a "bonus" section with some of the templates and added-value tools he included in the Guide.

The reviews at the bottom also help to lend credibility to the value of the content.
