Sitemaps vs. sitemaps – Yes, Virginia…there is a difference
Before getting into the details and purpose of XML Sitemaps, it’s important to understand the difference between a sitemap (lowercase) and a Sitemap (uppercase). A sitemap is an HTML file, typically accessible to website visitors, which contains a link to each page of a site that visitors might find useful. It is generally a single page composed only of text-based hyperlinks that can be used to find a specific page more easily – such as a “Contact Us” or specific product page – without being distracted by website design elements or page layout. While search engines are likely to access an HTML sitemap during the course of crawling a site, this page is not constructed or intended for indexing purposes.
An XML Sitemap, on the other hand, is an XML file that is not intended for use by a website’s visitors, but by the search engines themselves. The Sitemap itself is a UTF-8 encoded file that is created specifically to help search engines more efficiently index all of a website’s pages – particularly those that may not be linked to by outside sources or through the site’s text navigation itself. Google follows the accepted Sitemap Protocol 0.9, as published by Sitemaps.org. It’s also important to note that what we are discussing here are standard Sitemaps. There are also Video, Mobile, News, Code Search and Geo Sitemaps that can be created for different types of content.
