It appears that you have redirects setup or WordPress is redirecting for you through a process known as canonical redirect.
Performing this Search to get results from your site:
site:www.morgan-equester.com “Classic Showjumps”
Clicking either of the top two results returns “Status Code:301 Moved Permanently” and then is redirected to your home page.
This isn’t Google or Connections doing this. I hope that helps.
