Is your content gated or not? This is a new term for me, but it captures this marketing tactic:
When you offer an ebook, audio file, white paper or special report off your site, it's "gated" if you require a reader's email address. It's not gated if you allow digital downloads freely without any exchange of information.
This is stirring up a big discussion on blogs such as David Meerman Scott's Web Ink Now, Joe Pulizzi's Junta 42, and Newt Barret's Content Marketing Today.
Here's an example of gated: The Blog Squad's free ebook Better Business Blogging. It's an free give-away with plenty of information on how to use a blog for business results. We've used it for a while now as a lead-generator.
