Analytics for WP

This plugin is a perfect replacement for all of the cluttered plugins that dominate this market. If you only need a simple options page and a single field to drop in the tracking code then this plugin is for you.

I suggest the author change his options page menu item placement. It feels better to live under the Settings menu item instead of being a top level item.

Simple and effective

Analytics for WP plugin allows you to track your website by entering your google analytics tracking code.
