A site map is a comprehensive list of pages within a website's domain. It can serve three primary purposes: offering structured listings specifically designed for web crawlers such as search engines, aiding designers during the website planning phase, and providing human-visible, typically hierarchical listings of site pages.

Site maps can be displayed in a number of different map styles. Some styles display thumbnails for each page, others use text-only presentation.

Map styles include:

• Electrum – a simple thumbnail map style
• Electrum 2.0 – a variation of the Electrum style that works better on larger sites
• Isometric – a thumbnail map style using a pseudo-3D isometric projection
• Page Cloud – a thumbnail map style with pages clustered into 3D clouds
• Skyscrapers – an abstract representation of pages that looks like city blocks
• Thumb Tree – a hierarchical thumbnail map style
• Table Map – a plain text list of pages in a table
• Table of Contents – a plain text list of pages
• Tree View – an expanding table of contents

Site maps can also be exported in XML site maps format for use by the Google, Yahoo and MSN search engines.
