Long list with 15 (default number) YP results directly showing telephone number and free call button. Banner ads only on right side and bottom. Long URL with session ID, so result lists aren't used as SEM landing pages (Gelbe Seiten SEM Ads on Google for e.g. Munich and Restaurant are directed to the Gelbe Seiten homepage).
No other ads, not even banners. Usual elements: address, telephone number, free call button, email, www link, 5-10 keywords, logo and toolbox including: small map, routing, contact, download entry, send entry, integrate in address book, save on list.
