Implementing Google Analytics is usually fairly simple and requires that code be placed in the head or body tags of a web page or pages. Maian Cart has a single header / footer file, which means code added to these main files will automatically appear on all pages. Depending on where you need to place code, edit the following files: content/*theme*/header.tpl.php (Header Code)
content/*theme*/html/footer-google-analytics.htm (Footer Code)

Any additional footer code should be placed in the following file: content/*theme*/html/footer-google-analytics.htm (Footer Code)

Some people may prefer a self hosted solution, so Google doesn`t have access to data. A recommended feature packed open source solution is Piwik. It even has an iPhone app for anyone who`s interested.

After installation, add the necessary code to either the header or footer template files as detailed above.
