Copyscape is finding duplicates - possible to avoid?

Hello,

With the particular keywords I'm using for the project I'm working on (long tail keyword) copyscape is finding one site that uses the same keywords and noting it as duplicate content. There is no way I can change my keywords because the campaign is based on them. Is this fairly standard for more common keywords, and are there any penalties for it?

Thanks,
Ducky

If copyscape finds a duplicate its because there is a body text which is very similar to the text your using. You should rewrite your text until copyscape approve's it, or in some other way make sure that your text is unique.

Using same/similar text as another existing website, will make it real hard and possibly impossible for you to rank on your keyword of choice.

I agree, it doest just look at the keyword its looking at semantics and sentence structure as well as certain word densities, it wont throw a copy response just because your using the same keywords, rewrite your content.

Meh - apparently that isn't true. I've written my own article and now I've spun it and the long tail keywords are still flagging. Unfortunate I guess. The keyword (phrase) is 6 words long.
