How to set search engine to revisit for indexing in the script?
By using this so called REVISIT-AFTER meta tag you can tell the spider to come back to your website and index it again. This meta tag is used by several North American search engines.
<meta name="revisit-after" content="period">
Example how to use the meta tag revisit-after:
Add the following meta tag in the file "index.php" source:
<meta name="revisit-after" content="7 days"> <meta name="revisit-after" content="1 month">
Where do you add this revisit-after tag?
Once the "index.php" file is opened in a text editor then you should fine some lines which starts with tags "< meta" within the "< head >" section. Just place the code in a new line as like the example above.
In the example it clarifies to the bot (search engines crawler) to re-visit your site for crawling every 7 days for updating and the other one specifies 1 month.
