Short description of CoffeeCup Sitemapper 5.3: By placing a Sitemap-formatted file on your webserver, you enable the search engine crawlers to find out what pages are present and which have recently changed, and to crawl your site accordingly. Using Sitemaps to inform and direct crawlers, they hope to expand their coverage of the web and improve the time of inclusion in their index. Sitemaps are an easy way for you to help improve your coverage in search engine indexes.
