David and Heidi have put together an incredible resource, in The Digital Market Launchpad. They have put together a huge resource that will enable you to find your way in the online marketing world and best of all, you can do it all for free. The Digital Marketing Launchpad has given me access to so many tools, that I wasn't aware of. This should be part of any new or experienced online marketers resource library.
