我们曾连续报道了ClickForensics公司发布的全球CPC点击欺诈报告，继07年第三季度和第四季度的报告之后，08年第一季度报告也出炉了。可喜的是，无论是全行业还是google/yahoo的广告联盟，点击欺诈比07年第4季度都下降了一点点。请看下图。

全行业点击欺诈从上一季度的16.6%下降到了16.3%，两大广告联盟的点击欺诈从上一季度的28.3%下降到了27.8%。就全世界范围来看，原来的点击欺诈“强国”德国、法国、印度等等都出现了回落的情况，排在前三位的国家是摩洛哥（3.1%.），加纳（3.1%）和新加勒多尼亚（2.4%，在哪儿？）。

雅虎今天公布了第一季度财务报告，虽然与google的收入、利润的大规模增长无法相比，但是还好：今年第一季度，雅虎收入为18.18亿美元，比去年同期的16.72亿美元增长了9%；雅虎净利润为5.42亿美元，比去年同期的1.42亿美元有了较大增长，包括阿里巴巴首次公开募股相关的4.01亿美元的非现金所得收益在内。更详细的各项数字请看这里。

但是与google第一季度财报公布后股票大涨的情形相比，股市对雅虎的财报并不兴奋，上午还上涨了一些，但是下午一直回落到了昨天的水平。来具体看看财报当天两家公司的股价走势图。

凭着这种股价表现，雅虎不足以拒绝微软的收购大单。也许微软考虑到双方这么长时间的拉锯和雅虎毕竟上涨的财务状况，会增加几美元的单只股票的收购价格。

Compared to Google’s earnings homerun, Yahoo gets a single — but a hit is a hit 

(via venturebeat) Company earnings reports involve a lot of numbers. Unless you’re a student of Wall Street, or are following a company closely, it can be hard to decipher exactly what these numbers mean. Usually a good way to know how well a company did is to look at a stock price once the numbers are out. Last week we saw Google soar through the roof, going up over 20 percent upon beating estimates. Today, Yahoo’s stock is going up and down in after-hours trading — these swings are canceling each other out. This reflects Yahoo’s financial performance: decent, but nothing special. Read more.
