This tutorial assumes you have a working version of wordpress either on your own domain or a subdomain of siterubix.

This step by step guide will take you through verifying your WordPress website (including siterubix subdomain sites) when you don't have ftp access.

This guide starts with setting up Google Analytics on your WordPress site without using plugins.

Some of the other tutorials here on WA may show how to do this with plugins.

My preference is to add the scripts and codes to the header file.
(Note - If you upgrade your theme files, you may have to add the code back to the header.php after upgrade )
