Can anyone help me. This is crippling my seo. Every product and 90 percent of my urls have the random word "BOAT" at the start or end of the url.
I am using seo urls and im not adding this word to the urls. Doing a google search to bring up all my urls shows this ie site:https://boatlicenceplates.co.uk
I really would like some feedback on this as I know my rankings were a lot better before I moved over to 3.0.2.0.
Any help would really be appreciated.

Are you using a custom SEO module/extension or made changes to your .htaccess file?

Hi, no seo extension has been used at all. The only thing that has been amended in htaccess file is 301 redirect that i added when I switched over to ssl.
I can copy and paste if you would like to see it ?
