revisit

MetaExtension revisit

Is used to tell crawler-robots of search engines when to revisit the page. Should be set if the page content changes regularly.
As crawler-bots crawl regularly nowadays, this tag is marked as Deprecated.

We recommend using a robots.txt-file insteads of this meta-extension or a combination of both.

Usage

<meta name="revisit" content="5 days">

Also see revisit-after and robots.
