Nofollow links opencart

Hello,

I have a few opencart affiliate shops and i thinks it's better to add nofollow to all my external affiliate links.
Can someone help me out with this, is there a easy way in opencart to set all the external links to nofollow.

I think google doesnt like it when it sees so many outgoing links and that's why i would like to change it.

Hope someone can help me with this.

Can someone help me out?

I'm also looking for some guidance on this, any takers?

You should add meta tag on your site <meta name="robots" content="nofollow" />
