PowerMapper is a web crawler that automatically creates a site map of a website using thumbnails of each web page. A number of map styles are available, although the cheaper Standard edition has fewer styles than the Professional edition.


Map styles

Site maps can be displayed in a number of different map styles which arrange sites into a tree structure. 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
  • Thumbtree - a heirarchical 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 sitemaps format for use by the Google, Yahoo and MSN search engines.


The product received positive reviews in InfoWorld [1] for the 1.0 release in 1997, and subsequent reviews for the 4.0 release in Microsoft Technet Magazine [2] and WebsiteTips.com [3] were also favorable.

A list of problems commonly encountered by users is provided by the vendor in the PowerMapper FAQ.
