After publish several websites, I need something that can automate the creation of sitemap.
phpSitemapNG let you create sitemap files in different formats as e.g. the xml-based Google Sitemaps format, RSS, txt or html-based. It will spider your website and also your filesystem (of course, as you prefer). You can download and use it for free, the licence is GPL.
This tool will crawl the specified directory and later will tell google to read the sitemap to genarate sitelink on google search result
