作为饮料市场的挑战者,百事可乐几乎在所有涉及到的领域与可口可乐要一分高低。对网络营销工具的运用也不例外。首先,可口可乐公司在网上设立了虚拟互动工厂(www.vpt.coca.com),即通过游戏、故事及提供各个生产阶段的情况介绍,向网民解释可口可乐的生产过程,以吸引网友参观和了解。2000年8月,可口可乐公司又在中国建设以年轻人为诉求对象的集音乐、电影、聊天、游戏等频道为一体的中文网站,突出强调了互动与娱乐的特点,浓重的红底白色的波浪形“Coca-Cola”字母,古朴典雅而不失活力,是可口可乐永恒的背景。百事可乐也建立了与其公司形象和定位完全统一的中英文网站,以游戏、音乐、活动为主题,其背景则依然是标志创新和年轻的蓝色。百事可乐的网络营销策略,具体体现在以下三个方面:(一)媒介策略:与Yahoo携手2000年4月,百事可乐公司首先宣布与Yahoo进行全面网络推广合作;在音乐站点,如MTV.com的投放力度加大;同时还涉足于体育类网站,例如NBA.com和美国棒球联盟。网络广告投放活动是长期行为,从2000年1月至今从未间断。每年3月、4月,随着气温的升高,伴随饮料消费高峰期的来临,网络广告投放高峰期便告开始,通常会延续至11月。(二)创意策略:推崇激情针对可口可乐的传统广告及生活化的“可口”,百事可乐的网络广告较为活泼,无论是画面构图,还是动画运用都传达着一种“酷”的感觉。百事可乐善于使用“名人效应”为自己占领市场,请出青少年的偶像,往往是流行乐坛当红的歌手,作为自己的代言人。拉丁王子RichiMartain、“小甜甜”布莱妮和乐队Weezer先后出现在百事可乐广告中。从NBA到棒球,从奥斯卡到古墓丽影游戏和电影,百事可乐的网络广告总能捕捉到青少年的兴趣点和关注点。这也是为什么百事可乐会在MTV.com、NBA.com、美国棒球联盟网站上大投广告的原因。2001年中国申奥成功,百事可乐的网络广告独具匠心,将品牌的激情无限与气势非凡的内涵画面采用有动感的水珠传达出了百事可乐品牌充沛的活力。醒目的文字传达出百事可乐对北京申奥的支持。广告方案利用“渴望无限”和“终于解渴了”的双关语,将中国人对奥运的企盼巧妙地与百事可乐产品联系在一起。(三)竞争策略:针锋相对首先,体育角逐:可口可乐成为冬奥会的指定饮料,可以拿冬奥会大做文章。可百事可乐则利用NBA和美国棒球联盟寻找平衡点。在中文网站设有“百事足球世界”、“精彩足球”等栏目。其次,音乐角逐:这是百事可乐最精彩的策略之一。有百事音乐的主题活动,巨星、新星、音乐卡片、音乐流行榜、竞投场等等。最后,活动角逐:这是为自己创造品牌注意力的最好机会之一。例如,百事在网上发动网民投票评选“百事可乐最佳电视广告片”等等。

与传统广告相比,网络广告具有什么特点?
