As a part of Search Engine Optimization or SEO Services, it is very important to create a site map. Besides making it easier for your visitors to get around your web site, you make it easier for robots to crawl your page so you can be listed in search engines.
My experience has shown that when a site map is not used, it is very likely your entire web site won’t be crawled. In the past, I have had navigation on all my pages on my web site, but when I checked Google or yahoo, not all my pages have shown up. Using a site map seems to solve this problem. Your site map does not need to be fancy. All you have to do is to create a simple page and list every link in your web site. Also, make sure that the site map is made by text links. Don’t make links with images.
Google now has a program called “Google Sitemaps” that helps your web site with Google search engine indexing. In brief, this system can let you to keep Google informed of when you make changes to your web pages.Google suggest that it i better for you to have updated search results when it crawls your site, it is better if you can offer some information about your pages such as how often a page changes and when a page was last modified. It is very easy to setup. The simple way is to create an XML document and then upload it to your server.It is easy for Google to know the document’s location in your Google sitemap account. As it is easy to understand the process of Google’s sitemap feature and create the XML document, webmaster and web developer should easily be able to implement it.
