在网上搜集总结了以下几个方面，提供文本连接到站点上主要的页面，根据网站大小，网页数目的多少甚至可以连接到所有的页面；为每个连接提供一个简短的介绍，用以提示访问者这部分内容是关于哪一方面的；在网站地图和文本超连接里面提及最主要的要害词语，帮助搜索引擎识别所连接页面主题是关于哪一方面的；帮助引擎索引一些动态页面，由于一些页面将是动态产生的，假如不是用户行为调用将不会显示出来，可以将此连接放在网站地图上，以帮助引擎索引重要的动态页面；为了使网站地图吸引网络蜘蛛的访问，一定要在连接后面写上一定的描述性语句并使用此连接的要害词进行简单描述，但不能过渡的使用要害词，否则会适得其反；因为一般蜘蛛只抓前三级页面，所以网站地图越平越好，这里指的是逻辑路径，而不是物理路径。
