Enter a domain name into the text field and click on submit. This tool will will return whether Yahoo!'s Domain Match feed is showing a lander page (2-click) or listings (1-click) page. For lander, a list of categories (keywords) is shown. For listings, a list of categories and the current sponsored advertisers are shown. You can click on the sponsored advertisers on this page since it will not count as a paid click.
