This line might go on for quite a ways because the NOBR tag was used which disables automatic line breaks. As you can probably tell, NOBR stands for NO BREAKS. So, this entire paragraph will be presented as a single line. It's not likely you'll want to use NOBR very often, but it's there if you want to use it!

Inspect the source for this page. Notice that within the HEAD section of this page there is a TITLE tag. Your web browser probably displays this title at the top of its window. Incorporation of this tag is simple and easy.

The META tag presents information which is not seen by the user, but which is important to the user's computer and to search engines such as Google or Yahoo! The META tags on this page present information about the keywords found on the page, a description of the page, an expiration date, and a revisit-after time. Search engines use the keywords and description, in addition to page content and other factors, to help them to help their users to find information on the web.

By setting the expiration date to a date which has already passed, the user's computer is encouraged not to cache the page. This date can also be set to a future date to inform the user's computer to store the page until the specified date, but to reload it after that.

Google, Yahoo!, MSN, Ask.com, and other search engines and web indexes are also scanning the web for new pages and changes in the content of pages. The revisit-after value for the name attribute of the META tag provides a clue to the search robots used by these companies as to how often to revisit a page. If you frequently update a page a short time may be specified here. If updates are rare, a longer time should be specified.

Create a simple page on which you present information about the META tag. You should do some web research about the META tag and present at least five values which can be used with the name attribute which are not presented in this lesson. Explain the purpose of each of these values.
