Avoiding duplicate
content filters is not
as hard as one would imagine; just a little bit
of creative thinking can go
a long way towards setting your content apart from the rest of the scrapers and those too lazy to create their own content.
There are things you can do even when using previously published content on your site or blog. Rather than just copying and pasting content and linking back to it as others already have, consider how the presentation of this content may work to your advantage.
