kStats Reloaded began as a project to redesign StatPress Reloaded into a much faster and more up to date statistics plugin 
for WordPress. The original StatPress Reloaded is an amazing plugin, and can be found 
<a href="https://wordpress.org/extend/plugins/statpress-reloaded/" rel="ugc">here</a>.
Using kStats you can instantly see who’s coming to your site, where they are coming from, be it another web site or one 
of the many popular search engines, and much more. See up to the minute information on how many unique visitors you’ve 
gotten, how many pageviews they’ve resulted in, including information on which crawlers are visiting and indexing your 
Wordpress site.
kStats is much faster than many of its predecessors due to the fact that it takes a completely new approach to how 
it stores and maintains information. Using a slightly more complex database schema and running a daily aggregate of 
information allows it to reduce its SQL interaction by literally hundreds of queries.
This plugin is currently in its initial beta release — it is meant for beta testing only, and not intended for use 
on a live web site.
<h3>kStats Widget</h3>
Since version 0.5.0, kStats includes the option to display a portion of your statistics publicly on your blog via a sidebar widget.
The widget operates just like a regular text widget; you can place as many on your blog as you want, in any sidebar you have activated on your theme. The formatting is 
completely under your control, so feel free to make it look however you want to suit your blog. kStats will simply interpret any of the inserted macro codes that you choose 
to use and replace them with the appropriate information.
You can display your all-time totals, this months, todays, or yesterdays for any of the fields currently displayed on your statistics page (visitors, pageviews, spiders and 
feeds). In addition you are also able to include information such as visitors currently online, or data about the visitor currently viewing your page, including their IP, 
OS, or Browser.
<h3>Converting From StatPress Reloaded</h3>
Included in the archive is a conversion utility for StatPress Reloaded so that you don’t have to lose all the stats 
you’ve already recorded. This has been tested on StatPress v1.5.21, and is available from your plugins Options page.
Don’t worry about losing any of your data either if you choose not to use kStats. The conversion utility works from 
a temporary table, and does not affect your original StatPress data in any way.

WP Power Stats

I like this plugin very much. Plugin is Simple and easy to understand. Most things that I use are "Visitors & Page Views" graph and "Traffic Source".

Useful stuff!

What a pitty: search engine keywords stay empty.
And I know that there must be a lot of them because I crosscheck it with Google Webmaster Tools.

No search engine keywords

Discover your visitors in real-time, intuitively and with style.
