为什么同样类型或相近的网站，有的可以被收录，有的则不被收录？

有以下几个可能的原因： 1. 网站的内容不够优质：搜索引擎会倾向于收录有高质量、原创性、有价值的内容的网站。 2. 网站SEO优化不到位：搜索引擎算法有很多标准和规则，如果你的网站没有按照这些规则去操作，就会导致页面被搜索引擎忽略。 3. 网站没有足够的外部链接：如果其他网站没有链接到你的网站，搜索引擎可能会认为该网站不重要，从而不会收录。 4. 网站技术问题：如网站速度过慢、无法正确解析等，都可能导致搜索引擎无法访问你的网站。 5. 某些网站不允许搜素引擎访问：如robots协议的设置错误，可能会阻止搜索引擎收录该网站。

什么样的网页会被百度认为是没有价值而不被百度收录？

以下是一些可能会被百度认为是没有价值的网页： 1. 原创度低：内容复制粘贴自其他网站，没有独特性和原创性。 2. 内容质量低：网页内容质量差、无意义、过时或不准确。 3. 广告密度高：网页广告密度过高，影响用户体验，让用户难以找到有价值的内容。 4. 页面速度慢：网页打开速度慢，需要很长时间加载，用户体验差。 5. 多次违反百度规则：在过去多次违反百度规则，被百度扣除权重或直接罚站。

搜索某关键词，我的网页在搜狗的排序位置，和在其他搜索引擎的差异非常大，这正常吗？

这是正常的，各搜索引擎的搜索结果排序方式都是不一样的，有自己独特的计算方式，因此搜索某个关键词，每个搜索引擎出来的排序结果可能会有一定的差异。这就是造成排序差异的原因。

为什么我的网站收录数量越来越少？

您的网站所在的服务器不稳定，sogou spider在检查更新时抓取不到网页而被暂时去除。您的网站不符合用户的搜索体验。
