It's very easy to use, even for non-coders like me! I have used this tool in several projects without any issues so far.
The only thing that could be improved is how detailed the map can get at times - but it does help out with SEO as well if you need more than just basic keywords mapping. If your looking into optimizing websites using Google Webmaster Tools/Sitemaps then definitely give this software some time (and money). We were able to create an XML Sitemap from our website which we sent off to various search engines such as Bing web master tools etc., This was greatly helped by having all of these pages mapped correctly within dynomapping.
