版上有熟悉数据库+SEM+统计知识的进来看看这几道面试题吧？

有两个问题请教：
1.
How to design a SEO schema for analyzing how the search engines contribute
to user acquisition and engagement on social media website, like Facebook.

2.可以access internal database,但怎样可以预测我网站下12个月的advertising
product? 假设历史数据包括non-uniform top-line user and revenue growth.
