I have taken a text from a website and re-written the text. Now i´m going to publish this text on my website. Do you know some software i can use to check similarities i 2 texts? I don't want duplicate content.
Can you define what duplicate content is? Is it 100% different text, 10% different text, different adverbs, 5% different subject/verb agreements, what? I ask, because a lot of people use the hot phrase "duplicate content," but never define what it actually is. From Google's perspective, it *could* be an article that's just 30% different. If so, your two eyes and your one brain are the best piece software. BTW, please tell me that this other Web site was yours.
Most of us know about copyscape.com and articlechecker.com . But the best software is your own brains. I mean,manual checker is the best checker.
 Just run your rewritten article through ArticleChecker.Com. After making the necessary modifications on unintentionally copied three-word phrases and above, run it through Copyscape.Com using a Premium account since Copyscape captures rewritten phrases with the exact concepts as those phrases found on your sources, especially if the overall chronological order of concepts are copied. Finally, make the necessary modifications on your rewritten article, and you have a completely original write-up - with original in the sense defined by search engines.
For similarities between two articles, try dupecop or download wcopyfind and run both articles thru them.
I agree with market, please define what sort of duplicate content you mean....obviously not 100% different, but enough to be picked up?
I have checked out dupecop and wcopyfind. Running an article through wcopyfind right now. When i ran dupecop i saw that my articles where 30-51% uniqe. Is this "good"? Do you think i can publish these text's on my website without being punished by Google or some other search engine?
If you want to know what's "good" enough, all you need to do is test. Take an article and get it into Google (or try) using various step-downs from the original and then see what makes it, how they make it and what doesn't.
Hi John, The best thing that you can do is to re-write the article in your own words. Even if your article would sound like the original, it would pass as an original article since the words, phrases, sentences and paragraphing are totally different from the source. This way, there's no need for you to check your content for uniqueness or originality. However, if your intention is to merely pad up your site with contents in a snap, try Content Composer. It's an article spinning software that allows you to create a hundred versions of a single article (best for submission to directories) and can detect the percentages of similarities and difference of two or more articles (even a hundred articles, I think) in a single click.
I use Dupe Free Pro. Google it as I can't include urls in my post yet. It's free and has the benefit of taking a random sentence from your text and doing a search for it in Google to determine if there are duplicates online.
I have a tool that checks 10 pages on different sites or the same site at the same time [this can be increase to more pages]. It then shows you a report and highlight areas on the pages that are duplicate or similar. PM me if you want the link.
I've used copyscape for the last 12 months and it does work. Basically, I can check for dupllicate content from my sites, within the sites and also check for others stealing my work. I've even found a competitor who stole my layout, images and wording with little re-work (a few words here and there). The webmaster even copied the alt tags and had the same filenames for the images. Had a great time ringing up the Owner of the Company and threatening them with legal action (as if), but it resulted in the site changing quickly and the cache updated in a couple of months. Thing is duplicate content is a bugger and can really confuse the issue when trying to maintain decent rankings.
I have had instances where copyscape doesn't catch everything there is to catch. I'd be careful using it as the end-all, be-all if I were you.
