网络营销-文摘

不久前，公司有个产品的网站启用了一个新的domain, 从二级域名过渡到顶级域名。发现google spider在新域名上抓取的网页来来回回就那几万页， 原先google的收录页数可是百万数量级的。这对追求PV的网站来说，绝对是致命的打击。 幸运的是得到google的答复说这个新domain原来是个bad domain(受过google惩罚的)， 可以reinclusion。 具体的操作方法现在可以用 google sitemap里的Request reinclusion。

Click-through Rate (CTR): CTR is the metric used to determine what percentage of users click on a given listing. CTR is calculated as: clicks/impresions
A number of factors influence CTR in addition to rank. These include title, description, ad relevance, and industry. While all of these variables should be considered when you work to improve your CTR, the drop in CTR by rank was observed consistently in the data for this research, independent of these factors.

In summary: To get a click, your ad first needs to get an impression, then someone needs to click onyour ad. To determine what impact rank has on impressions and CTR, we analyzed hundreds of millions of impressions and clicks for tens of thousands of keywords across a diverse set of industries and categories as they moved up and down in rank.

• Provide unique perspectives and content on topics
• Think about their visitors, making sure the sites meet their visitors’ needs
• Give visitors reasons to come back, and other sites reasons to link to them (they update content regularly, and most offer in-depth information, such as tutorials, reviews, or in-depth explanations).

无非是提供独有的、高质量的，频繁的内容更新，且辅之以具有相关性的反相链接。
