Top 15 Tools for Checking Duplicate Content

If you have a website and you accept guest posts then some times it is possible that the guests who are contributing articles to your website may be copy pasting content. 
Any copy pasted content on your website will ruin and hamper the reputation of your website after all. The content would have been published on some other websites and when people come to your website and see the same content, then they get a wrong impression about your website. In order to prevent such mistakes, it is the duty of the editor of any website to use a good tool which helps find copied content. In this article, I have included the names of 15 such tools which help to detect duplicate content. Using these tools is very easy as you just need to paste the content you want to check for copy paste and then you have the results in front of you. Now, it is very necessary that you make efficient use of these tools to make sure that you don’t put duplicate content on your website.
1. Dupe Free Pro

The issue of “duplicate content” is not a new phenomena. The problem has existed online since the internet began. Of course, back when the web was in its infancy, duplicate content was only an issue for the author in terms of copyright infringement. The search engines (Google, Bing, Yahoo, etc.) just weren’t so concerned about it then. However, these days, with the internet so hugely competitive and so open to abuse, the search engines have had to get smarter and work much harder at filtering the content they deliver in their search results. After all, the most important asset they have is the quality of their search results. Without useful search results, they would lose trust with their visitors and searches would drop off, which would directly effect their ability to generate revenue.

The original DupeCop duplicate content checker – allows you to compare two pieces of text and find out how unique the second is in percentage terms.

4. Duplicate Content
The tool takes into account two parameters when compaing URLs: it considers the similarity degree for both textual content and HTML markup. This allows you to check whether two texts are substantially similar and the alikeness of the structure of the pages. That is why it is important to have content that is as unique and original as possible. The web sites that risk the most are those that provide third-party content, and the online shops that use the manufacter’s description for the products they sell: if you run such a web site, you should try to avoid using 100% copied-and-pasted content. If that is not possible, then it would be useful to at least add a few lines of original content to the pasted text, such as a commment or discussion.
Search Engines are known to act upon websites that contain Duplicate / Similar content. Your content could be similar to other websites on the Internet, or pages from within your own website could be similar to each other (usually the case with dynamic product catalog pages). This tool allows you to determine the percentage of similarity between two pages. The exact percentage of similarity after with a search engine may penalize you is not known, it varies from search engine to search engine, Your aim should be to keep your page similarity as LOW as possible.
