			<content:encoded><![CDATA[<p>不知是哪天，或许是7月月底，英国eBay发布了下次更新的框架。刚刚终于抽空看了一下，BM的一个改动勾起了我的邪念。。。</p>
<p> </p>
<blockquote><p><strong>Recent sales score for Fixed Price &#8211; including impressions count</strong><br />
We’re refining the way we measure recent sales. Fixed Price listings will have a performance score based on the listing’s recent sales in relation to the number of recent impressions it got. An “impression” is any time a buyer sees a search results page that includes the listing.</p>
<p>For example, in the new version of Best Match, a listing with 100 recent impressions and 10 recent sales will score higher than a similar listing with 1000 recent impressions and only 10 recent sales.</p></blockquote>
<p> </p>
<p>它就是这么说的。于是我恶毒的想，若是查询一些特定的关键词，让每次出现的搜索结果不包括自己的listing。这样一来，竞争对手销售与impression的比例肯定就会低。为了绕过eBay可能的扫描过滤系统，写个脚本，用上自动切换代理。每30秒发送一次搜索请求，一天24小时能请求2880(=24*3600/30)次。如果几台机子同时挂着刷，或者再把脚本升级到一个小程序，那针对某个特定关键词的影响还是可观的。。。</p>
<p> </p>
<p>假设eBay确实存在这个所谓的漏洞，对卖家而言，最好的就是大家统一标题。不过仍然可以通过设定价格区间来达到上述目的。。。对eBay而言，最简单的方法可能就是只计算登录（或者搜索过后登录，可以通过跟踪cookie实现）用户搜索产生的impression。</p>
<p> </p>
<p>当然，eBay的大神多了去了，这大概只是近日状态不佳和整日瞎忙共同作用下的睡前白日梦。</p>
<p> </p>
<p>PS：诚信乃立人立业之本，只不过以前学NS时找漏洞的毛病又犯了。。。</p>
