The meta tag REVISIT-AFTER defines how often a search engine or spider should come to your website for re-indexing. This tag is used for websites that change their content and on a regular basis. This tag can also be beneficial in boosting your rankings if search engines display results based on the most recent submissions.

The meta tag ROBOTS, supported by several major search engines, controls whether search engine spiders are allowed to index a page, or not, and whether they should follow links from a page, or not. The meta tag can contain one or more comma-separate values. The noindex value prevents a page from being indexed, and nofollow prevents links from being crawled. Other values recognized by one or more search engines can influence how the engine indexes pages, and how those pages appear on the search results. These include noarchive, which instructs a search engine not to store an archived copy of the page, and nosnippet, which asks that the search engine not include a snippet from the page along with the page's listing in search results.
