Remove Cached Pages
By default, Google caches pages and displays them, along
of each search result. The benefit is that if that web page
or site is down, it can still be seen by the cached page.
But some business may not want to do this for security reasons,
time sensitive information, etc.
To prevent Google and other like-minded search engines from
caching your page, put the following code in the header <HEAD></HEAD> of
each HTML page your want to block:
To prevent only Google, use this line instead:
Remove
Snippets
When results for your pages are displayed in Google, a few
sentence description accompanies the link, to help the user
determine the relevance of your web page or site. These brief
descriptions are called "snippets" in Google.
To have Google not display snippets, and only display a link
for a particular page, put the following code in the header <HEAD></HEAD> of
each HTML page you want to remove snippets for:
One caveat is that removing snippets also removes the cached
page for that particular HTML document.
Remove Individual Pages
An alternative to using a robots.txt file for Google and select
other engines, is to use META tags to block certain pages from
Google and other search engines.
To block a page from all obeying search engines, put the following
code in the header <HEAD></HEAD> of each HTML page
you want to remove:
To only remove the page from Google, enter the following instead:
This tells the search engine robot(s) to not include that
page in their index, but to also ignore any of the links
included within the page. |
