I found my problem.

My redirect to my 'home.php' when entering a test url into the google structured data test tool, was coming from a line at the bottom of the reCaptcha_js.tpl.

{* {if $main eq "catalog" && $cat eq "0"}{else}<noscript><meta http-equiv="refresh" content="0.0;url=home.php"></noscript>{/if} *}

Thanks to Paul, Phil and Steve for helping my muddle through this.

Hopefully this is helpful to others that may run into this problem.
