Using rel=”next” and rel=”prev” to hint Pagination to Search Engines

Since link tag specifies the relationship between current document and the linked document the attributes rel=”next” and rel=”prev” gives a strong hint to Google to treat the specified pages as a logical sequence. For example, you have created an article with three pages, page1.html, page2.html, page3.html.
In the first page you can add the following to indicate the next page.

1 <link rel="next" href="http://www.mysite.com/page2.html">

On the second page you can add links to the first and third page.

1 2 <link rel="prev" href="http://www.mysite.com/page1.html"> <link rel="next" href="http://www.mysite.com/page3.html">

And finally in the third page the link should be

1 <link rel="prev" href="http://www.mysite.com/page2.html">

This will help the search engines to treat your pages as sequence and index them accordingly.
Apart from the above attribute values “rel” attribute of link tag can have many other values. All these values indicate the relationship between the current document and the linked document.
