Providing a Description of Your Page
Search engines try to help visitors distinguish between results by adding information about the individual pages next to their URLs. Some search engines let you specify the description that should appear next to your page.
To control your page's summary:
Figure 24.4. You can offer search engines a concise description of your site.
Figure 24.5. Yahoo begins the listing description with what you've put in the description meta tag and then adds the initial content of the page itself.
