Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate.

用如下技术：
(1) 网页标题(title)的优化；
(2) 选取合适的关键词并对关键词进行优化；
(3) 元标签的优化；
(4) 网站结构和URL的优化；
(5) ，禁止蜘蛛抓取网站后台页面；
(6) 网页内部链接的优化；
(7) Heading标签的优化；
(8) 图片优化；
(9) 网页减肥技术。
7. 使用C++、C#和Java等任意一种编程语言，设计并实现一个简单的网络蜘蛛爬行程序，要求在输入关键词、设置爬行深度和初始网页URL之后能够实现网页搜索，输出包含关键词的网页的URL和网页标题。【注：实验7为补充实验，不要求每个同学都完成，感兴趣者可自行实现该程序，不计入实验报告评分。】
三、实验要求
1. 研究几种常用的网络蜘蛛爬行策略，填写相应的表格，表格必须填写完整；
