some times unfortunately it is easy for someone to copy content from a web page to their page it can be easily copied but How can I check if anyone is stealing my website content so that i can stop that.

I think http://www.copyscape.com/ will help you to get detect copy website content. I have used to my website. It is still protected.

You can check your stolen content in three ways:

• Copy your content and check it directly on web.
• Check it through copyscape.com
• Check content on plagiarisma.net

Plagiarisma and copyscape are most reliable and effective way to find copy content.

Copyscape.com is the best way to check duplicate content. If anyone has stolen your website content then you can find it from here. There are other website also for checking duplicate content but copyscape is the best to check copied content.
