The best kind of content is information presented in a straightforward manner along with the all-important links to your website. Matt Van Atta suggests that, “it could be contained in a PDF that facilitates ease of downloading and assures the user that no virus or spyware is associated with downloading the content. Reports and online white papers are ideal; articles are good, too.
Sure, you could make your content more visually exciting through such formats as video clips and Flash animations. But you’re likely entering dangerous territory by taking this approach. These options result in larger file sizes that take longer to download (and the 56k modem hasn’t completely faded yet). They also give the impression that you’re providing a lot of sizzle to hide the fact that there is little or no steak.
Which leads to the most important point: Whether you are tapping into an existing niche market or creating your own, viral marketing content should show that you know your subject matter. Those who download the content should trust your site. Such trust can go a long way when it comes to promoting products or services on your site.”
