well, for faq and contact pages, you can just edit their templates from vb admin cp.
Then you need to look into your <head></head> area, you will see something like this:
PHP Code:
<head>
{vb:raw headinclude}
<title></title>
{vb:cssfile faq.css}
{vb:raw headinclude_bottom}
</head>
All you need is to edit what you want and make everything new if you like. find out where meta tag reside and then modify what necessary.
most of the times, meta tags are placed in
headinclude template. Therefore you need to add your manual code in your faq, contact and other pages you like and remove
headinclude i.e. {vb:raw headinclude} from faq, contact and other pages you want to customize meta tags...
