A copyright disclaimer asserts your legal right to Topperaddaindia.com, and it can help deter people from stealing content from that website. It makes it clear who owns this website and that they're willing to protect their right to its contents.
The copyright disclaimer typically has four parts: the copyright symbol, the year of the page's publication, the name of the website's owner, and a statement reserving the rights of the site's owners to the site's content. The last part is optional, although it's encouraged for clarity and completeness.
