If you are aware of rel=canonical suggested by Google, that acts as a strong informer for duplicate content, big G has now introduced 2 more rel attributes. You can now optimize your pagination with rel=“next” and rel=“prev” to define your pagination links and relationship between multiple URLs of your website.
A paginated series may take many shapes on the web like it can be multiple pages of an article, multiple pages on an e commerce or shopping site, or a forum thread divided in a sequence, a series of blog posts like tutorials or a list of items etc. Now you can easily let the search engines know the relationship between next page and previous page corresponding to the current page by using a simple markup.
If you choose to add rel=”next” and rel=”prev” markup inside your anchor link within a series, you’re giving Google a strong hint that you’d like the visitors to go the the most relevant pages to that article.
However there is a limitation with this markup if you offer a full page apart from paginated links to read the entire article without navigating through pages back and forth then consider reading on View-all in search results for more information. As quoted by Google
Because view-all pages are most commonly preferred by searchers, we do our best to surface this version when appropriate in results rather than a component page (component pages are more likely to surface with rel=”next” and rel=”prev”).
Optimize Pagination links on your Website
The article is self explanatory and you simple need to add rel=”next” for a link to the next page and rel=”prev” for a link to previous page. But if you would like to see a brief tutorial on implementing this new markup on your website then head over to Official Google Webmasters post on pagination links.
