????數字營銷咨詢公司eMarketer最近的報告顯示，Facebook和谷歌今年的展示廣告收入都將有所增長。谷歌增長速度稍快，展示廣告的市場占有率從去年的13.5%增加到了今年的15.4%，Facebook則從去年的14.1%提高到今年的14.4%。eMarkerer預計，到2014年，谷歌將會占有21.2%的市場，而Facebook則是15.5%。

????通過推出廣告競價系統和上周開始測試的移動廣告網絡等一系列舉措，Facebook可以在市場上分到更大的蛋糕。如今Facebook也開始認真對待搜索廣告市場。這些舉措有助于Facebook股票的上漲，使得它的股票估值合理而有吸引力。不過要想讓股價持續好轉，就意味著Facebook要繼續深入谷歌的核心業務。

????因此，谷歌和Facebook的斗爭并未結束。Facebook已經把這差強人意的一年和失敗的首次公開募股拋到腦后。接來下，硅谷最有趣的一件事，想必就是Facebook和谷歌新一輪的競爭了。

????According to a recent report from eMarketer, both Facebook and Google will see display-ad revenue grow this year, although Google will grow faster to 15.4% of the display-ad market from 13.5% last year. Facebook will grow to 14.4% of the market from 14.1% last year. By 2014, eMarketer estimates, Google will control 21.2% of the market and Facebook 15.5%.

????But efforts like Facebook Exchange and the mobile ad network the company began testing last week could give Facebook a bigger piece of the pie. And now it's getting serious about search ads as well. Taken together, these initiatives help support the Facebook bulls who say the stock is attractively priced right now. But turning its stock price around will mean moving deeper into Google's home turf.

????So the Google-Facebook rivalry isn't going away. As Facebook puts its not-so-stellar year behind it -- its bruising IPO with it -- the most interesting story in the Valley may be this renewed rivalry.
