Keeping Pages From Being Archived

Some search engines save a copy of your Web page and offer it as an alternative if your site is down or otherwise inaccessible. However, there is no guarantee that this cached version is up to date. If you'd rather your page not be archived on a search engine's server, you can tell the robot not to archive it.

To keep search engines from archiving your pages:

In the head section of your page, type <meta name="robots" content="noarchive" />.

Tip

Presently, Google is the most important search engine that archives Web pages. If you'd like to keep only Google from archiving your pages, you can specify googlebot instead of robots as the value of the name attribute above.

Figure 24.9. Some search engines, like Google shown here, keep a copy of the pages that they index so that visitors can see what's on the page even if the page is not available.

Figure 24.10. When a search engine's robot encounters this page, it will continue to index the page, but it won't archive it (and thus won't be able to offer a cached version should your page (or server) be unavailable).
