Frequently Asked Questions

How Does Your Site Work?

DuplicateCheck.net uses search engines to determine if a given article has been duplicated on the internet.

How much does your site cost?

After using the 5 free searches that every unique new account is given, each additional search costs $0.035 or $3.50 per 100 searches.

How can I pay you for more searches?

We accept payment through Paypal. Paypal is safe and secure online payment source.

An article that I know is duplicate is showing as not being plagiarized, why is that?

Because DuplicateCheck.net relies on search engines to determine if an article uses duplicate content, there will be times where we will give false positives because of bad reports from the search engines. In order for the system to work, the content must be indexed by the search engines so that it can be properly compared.

How accurate is your site compared to other online duplicate content checks?

We have had reports from users that our service is more accurate than most of our competitors. Our system is completely unique and uses sophisticated technology to give you more accurate results and show less false positives.

We also are looking for ways to make our system better so if you find that we miss something that the competition finds, we'd love if you messaged us with the results and article text so that we make our system more accurate.
