seo - Using noodp meta tag in a robots.txt file -

-

is possible add seo tags such 'noodp' robots.txt file instead of using <meta> tags? trying avoid messing our cms template, although suspect may have to...

could try similar this...

user-agent: * disallow: /hidden sitemap: www.example.com noodp:

i think robots.txt takes precedence on meta tags? noindex instance, crawler not see page in question. noodp however, still case?

you can't robots.txt, can same effect using the x-robots-tag response header.

add appropriate part of .htaccess file:

header set x-robots-tag "noodp"

this tells server include following line in response headers:

x-robots-tag: noodp

search engines (that support x-robots-tag) interpret header line same way interpret 'noodp' in robots meta tag. in general, can put in x-robots-tag header can put in robots meta tag. note page must not blocked robots.txt, otherwise crawler never request page, , therefore never see header.
