IMPORTANT: 3.0 supports cahing plugins!
When someone visits a post or page (not a search engine bot crawler), it adds 1 count views to its counter.
But this is not all, the counters are split in days, weeks, months, years, so you can see stats and display any stat day.
Then you can display this views with the provided shortcode [post_view] or use the widget to display a top (or less) posts list.
You can also use [most_view] in a post/page to get a top (or less) post most viewed.
If you were using another kind of plugin before and don’t want to lose your counters, this plugin can keep them!

Post Views Count (Support caching plugins!)

This plugin counts views for post and pages, shortcodes [post_view] & [most_view] are available, also a widget "Most Viewed Posts" is.

This is a helper plugin to allow you to build WordPress queries using WordPress.com stats.
This plugin uses the WordPress.com stats (packaged in Jetpack) to find out your most popular posts. You must be running Jetpack for this plugin to work. I recommend running Jetpack for at least 30 days to get useful data.
It asks for the 100 most popular posts over the past 30 days. This includes both posts and pages, since their stats don’t let you filter based on post type. I filter this list down to just posts and then store its ranking as post meta (‘be_stats’).
You can <a href="https://gist.github.com/billerickson/4997202" rel="nofollow ugc">write custom queries</a> to list popular posts, or use the <a href="https://wordpress.org/extend/plugins/display-posts-shortcode/" rel="ugc">Display Posts Shortcode plugin</a> to do it for you. Examples using the shortcode plugin:
[display-posts orderby=”popular”] – Lists the 10 most popular posts 
[display-posts orderby=”popular” posts_per_page=”4″] – Lists the 4 most popular posts 
[display-posts orderby=”popular” posts_per_page=”4″ tag=”basic”] – Lists the 4 most popular posts tagged “basic”
<h3>For Developers</h3>
There are a few filters available to you for customization. Refer to the plugin’s code for more information.
be_stats_args – arguments passed to WordPress.com Stats API. 
Default: array( ‘days’ => 30, ‘limit’ => 100 ) 
Example: http://www.billerickson.net/code/customize-be-stats-arguments/
be_stats_update – Conditional for determining if stats data should be saved 
Default: ‘post’ == get_post_type()
