nosnippet From Google help: "A snippet is a text excerpt from the returned result page that has all query terms bolded. The excerpt allows users to see the context in which search terms appear on a web page, before clicking on the result. Users are more likely to click on a search result if it has a corresponding snippet." This value of NOSNIPPET removes the text snippet.
noarchive From Google help: "Google keeps the text of the many documents it crawls available in a cache. This allows an archived, or "cached", version of a web page to be retrieved for your end users if the original page is ever unavailable (due to temporary failure of the page's web server). The cached page appears to users exactly as it looked when Google last crawled it. The cached page also includes a message (at the top of the page) to indicate that it's a cached version of the page."
"If you want to prevent all robots from archiving content on your site, use the NOARCHIVE meta tag."
