On the web, every direct marketer wants to be found. A site map makes it easier for search engines to find all the pages on your site.
Search engines use programs to look at and index all the pages on your web site. The programs are “bots” (short for “robot program”) that usually run late in the evening when there is less web traffic. A bot program will start at your home page and “read” and index all the content (words and images). Then the bot will follow every link and index each of those pages. For dynamic sites with tens of thousands of items this can take some time.
A site map is a directory of all the pages on your web site. The major search engines look for a site map before they start indexing a web site. A site map makes it easier for the bot to find all the pages on your web site.
Directions automatically builds a site map for all the pages on your site.
