Website maps

Quote from Wikipedia on sitemaps: http://en.wikipedia.org/wiki/Sitemaps
The Sitemaps protocol allows a webmaster to inform search engines about URLs on a website that are available for crawling. A Sitemap is an XML file that lists the URLs for a site. It allows webmasters to include additional information about each URL: when it was last updated, how often it changes, and how important it is in relation to other URLs in the site. This allows search engines to crawl the site more intelligently. Sitemaps are a URL inclusion protocol and complement robots.txt, a URL exclusion protocol.
Sitemaps are particularly beneficial on websites
where some areas of the website are not available through the browsable interface, or
where webmasters use rich Ajax or Flash content that is not normally processed by search engines.
The webmaster can generate a Sitemap containing all accessible URLs on the site and submit it to search engines. Since Google, MSN, Yahoo, and Ask use the same protocol now, having a Sitemap would let the biggest search engines have the updated pages information.
Sitemaps supplement and do not replace the existing crawl-based mechanisms that search engines already use to discover URLs. By submitting Sitemaps to a search engine, a webmaster is only helping that engine's crawlers to do a better job of crawling their site(s). Using this protocol does not guarantee that web pages will be included in search indexes, nor does it influence the way that pages are ranked in search results.

Now, Website maps are Info graphics because they provide a visual to help us navigate around a website. You can do some interesting things with sitemaps. I designed a portfolio website for myself for my final project at college, and to present the artwork i decided to lay it out like a sitemap. I am trying to find a picture of this, BUT I CANT BECAUSE MY HARD DRIVE BROKE with all my work on. so i have lost EVERYTHING >_<
