Free Duplicate Content Checker Tool

What is an acceptable percentage?

No exact answer really. There are so many factors...there isn't just a hit yes or no exact # answer.

Depending how a site is configured, what external links a site has, the size of the site, etc etc etc a bad number might range anywhere from 70 to 85% on up or so.

Aaron, thanks for letting us know about this tool. Gives a whole different perspective on how my site might appear to the search engines in regards to duplicate content issues.

Don't know why I got a runtime error - but maybe I need to download it and do a reinstall.

It is extremely helpful.

Brian - the lower the percentage of duplication/similiarity, the better.

Cool. Thanks Aaron for this usefull information. Frankly I still bother thinking about duplication/similiarity content.
Now it is time to proove it. I will try this. And see the traffic result. Also Thanks to Sufyan the creator

Hey Aaron,

This tool isn't working... do you know of any others?

Is there anything in the marketplace (whether free or paid) that will look at my site, and comb the internet to determine pages with my articles/content on them? This would be most valuable than comparing one site to another... I'd have to know the site before for most of these to work!

Attributor is good stuff. And there is also Copyscape.

Hello
I first have to tell you that I love this site, Ok on to business, I wanted to check my site for duplicate content and found your link is not working. Just a little heads up!!

Thanks,

Thanks for the info about Attributor. I see that there is an enterprise solution available. Is this something that you've tried? I'm after something to use commercially but not sure which product to go for?

Regards,

Jon

I got a trial use of it Jon. It looked interesting...but I did not give it as much attention as I could have/should have because I am always doing way too much work and have my attention pulled in 10 different directions at any point in time.
