How to Avoid Search Engine indexing of a particular page?

Best way is to use write following Meta Tag below <head> tag

<meta name=”robots” content=”noindex,nofollow” />

Google recently covered this more as an option. But as Google also explained, links from a page with this tag might still get crawled. That’s because if anyone else links to a particular page WITHOUT a nofollow value, then the search engine will follow that link.

    NOINDEX – prevents the page from being included in the index.

    NOFOLLOW – prevents Googlebot from following any links on the page. (Note that this is different from the link-level NOFOLLOW attribute, which prevents Googlebot from following an individual link.)

    NOARCHIVE – prevents a cached copy of this page from being available in the search results.

    NOSNIPPET – prevents a description from appearing below the page in the search results, as well as prevents caching of the page.

    NOODP – blocks the Open Directory Project description of the page from being used in the description that appears below the page in the search results.
