Is it possible to add SEO tags such as 'noodp' to a robots.txt file instead of using `<meta>` tags? I am trying to avoid messing with our CMS template, although I suspect that I may have to...

Could I try something similar to this...

`User-Agent: *
Disallow: /hidden
Sitemap: www.example.com
noodp:`

I think robots.txt takes precedence over meta tags? For noindex for instance, the crawler will not even see the page in question. For something like noodp however, is this still the case?
