Installing Visual Visitor in WordPress is a fairly straightforward process.  Please follow the steps listed below - 

1. Login into your WordPress site in your Dashboard go to Appearance
2. Then click Theme File Editor
3. There you will find the file named Theme Footer or footer.php  (before editing the file copy the content to a notepad file so that if something gets wrong you can paste original code back in to start again)
4. There you will find a code for original theme which will look like this:
   <?php (‘name’); ?> is proudly powered by<a href=”http://wordpress.org/”>WordPress</a>
5. Place mouse right before the original code </footer> tag and press space bar and add your script.
   
6. Click update and the footer will be changed

* Visual Visitor strongly recommends making a backup copy of any files that you plan to change within WordPress during this procedure.

** Visual Visitor is not responsible for any issues that might arise due to changes made in WordPress.
