| Yahoo Information When one web page
redirects to another web page, Yahoo! Web Search will sometimes index
the page content under the URL of the entry or "source" page, and
sometimes index it under the URL of the final, destination or "target"
page.
Yahoo!'s Web crawler recognizes standard HTTP result codes. The basic
types of redirect recognized are:
- 301 - Permanent Redirect
- 302 - Temporary Redirect
- META Refresh: <meta http-equiv="refresh" content=...>)
will be recognized as a 301 if it specifies little or no delay or as a
302 if it specifies noticeable delay.
Yahoo! Web Search General Guidelines for Indexing Redirects
The examples below illustrate when Yahoo! web search normally records
the "target" page URL or indexes the "source" page URL.
 |
 |
| When a page in one domain redirects to a page in another domain,
Yahoo! records the "target" URL. |
| |
 |
| When a top-level page in a domain presents a permanent redirect
to a page deep within the same domain, Yahoo! indexes the "source"
URL. |
 |
| When a page deep within a domain presents a permanent redirect
to a page deep within the same domain, Yahoo! indexes the "target"
URL. |
 |
| When a page in a domain presents a temporary redirect to another
page in the same domain, Yahoo! indexes the "source" URL. |
