On website there are pages of 2 conceptual types:
- pages that makes sense for robots (e.g. Google) to index (show in search results)
- pages, that doesn't make to index (e.g. "No Permissions", "Form Submitted Template")
For later page category it makes sense to add following into <head>:
<meta name="robots" content="nofollow, noindex, noarchive"/>
Solution

<inp2:m_if check="c.current_Field" name="MetaKeywords"><meta name="Keywords" content="<inp2:c.current_PageInfo name='MetaKeywords'/>"/></inp2:m_if>
