When displaying a single post, you might want to show links to the previous and next posts in the same category.
That’s fine; WordPress let’s you do this with <code>previous_post_link()</code> and <code>next_post_link()</code>.
But what if that post is in multiple categories?
What if the user came to that post from a tag page or from an author page? Wouldn’t it make more sense to display previous / next posts from that particular set?
Well, you can do this with a similar pair of functions, provided by this plugin: <code>previous_post_smart()</code> and <code>next_post_smart()</code>.
Here’s how it works:
Whenever a visitor goes to an archive page (category, tag, date, author, search etc.), the plugin notes which archive it is in a browser cookie.
Then, if the visitor goes to a single post from that archive page, the plugin generates the prev / next links based on the information in the cookie.

Cresta Posts Box

In free version, you have to chose to show only previous or next post. Too limited to be really useful.

Too poor in free version

Show the next or previous post in a box that appears when the user scrolls to the bottom of a current post.
