When a page of your free GeoCities site loads, a frame containing targeted advertising will appear on the right side of the page. Visitors can click the arrows that appear on the left side of the frame to minimize it anytime.
If your site cannot display the ad frame for any reason, the GeoCities Ad Square will appear in the top-right corner of the page instead. This temporary window appears in an expanded view and then collapses to display only the Yahoo! GeoCities logo. Visitors to your site can minimize or close the Ad Square anytime.
Please note that GeoCities Plus and Pro member sites do not include any ads.
