Yeah you are correct.
Heres what I'm doing now to
SEO WordPress
Code:
<?php if(is_single() || is_home()) { ?>
<meta name="googlebot" content="index,follow,noodp,noarchive" />
<meta name="robots" content="all,index,follow" />
<meta name="msnbot" content="all,index,follow" />
<?php } else { ?>
<meta name="googlebot" content="follow,noodp,noindex,noarchive" />
<meta name="robots" content="follow,noindex,noarchive,nocache" />
<meta name="msnbot" content="follow,noindex,noarchive,nocache" />
<?php }?>
And then my robots.txt is less restrictive than initially because we still want google to follow our pages, and they won't if its disallowed in robots.txt.
