Jetpack is a plugin that includes a number of useful features including spelling and grammar proofreading, email notifications for subscribers, support for LaTeX markup and site statistics. See: Jetpack.
To install Jetpack, do the following:
- Go to your blog Dashboard
- Click on Plugins > Installed
- Activate the “WordPress.com Stats” plugin
Once this plugin is activated, you’ll see a “Sites Stats” page in your blog’s dashboard. Initially this panel will contain instructions for linking the site to a wordpress.com account.
While Jetpack is designed to replace the WordPress.com Stats plugin, blogs that have been using the WordPress.com Stats should not update to Jetpack yet. We have had reports that Jetpack does not provide access to stats generated by the WordPress.com Stats plugin, so if retaining this historical data is important to you, please wait until this issue is resolved.
