关于Google Sitemap的几点认识

　　很多朋友刚步入SEO行业，可能是带着很多疑问的，比如:我的站排名为什么不太好?我的站的收录为什么这么少等。

　　当你咨询一些SEOER时，他们也会教你一些措施，其中关于Google的收录就有一条Google Sitemap中文名为google网站地图。

　　Google Sitemaps是google在2005年6 月份推出的一项服务，关于Google Sitemap(s)，google是这样描述的:

　　The Sitemap Protocol allows you to inform search engine crawlers about URLs on your Web sites that are available for crawling. A Sitemap consists of a list of URLs and may also contain additional information about those URLs, such as when they were last modified, how frequently they change, etc.

　　Does Google misjudge the importance of pages on your website?

　　Perhaps you have a product page in your catalogue that is linked to from lots of sites on the web and has a high pagerank - this page may often appear above your home page in the search engine results page even for searches that are for your company generally, not that specific page. The sitemap protocol enables you to indicate the relative importance of the pages on your site.

　　Do you have dynamic content that is not indexed by search engines?

　　There are many ways of tackling this problem, the sitemap protocol is a new tool to help ensure that your site is indexed in depth. As the sitemap protocol is new (and still in beta) it should not be relied upon to ensure deep indexing.

　　Do search engines crawl your site too much?

　　The sitemap protocol enables webmasters to suggest to search engine robots how often particular pages should be indexed. This could potentially reduce the bandwidth used by search engine robots on dynamic sites.

　　对于Google Sitemap，枫林是这样熟悉的，现在有很多的在线生成网址，当然还有一些Google sitemap在线生成软件之类的东西，但是这类工具都有个特点，都是完全的机器或者智能化操作，这样虽然方便也很节约时间，但是带来更多的不良因素。

　　在线生成工具往往过于笼统的加入某些网址，甚至有些加入的网址是该站早一不存在的，这样导致的后果是什么呢?Robot无法抓取，这也就是很多朋友查看Google Sitemap帐户中
