Im in the process of creating a new, fairly large site which is layed out as follows; at the root I have my main site, which is HTML in a subfolder called BLOG I have a wordpress Blog in a subfolder called SALES I have a Magento setup. Can anyone advise how I should be setting up my sitemap.xml? should I have 3 sitemaps, or just one at the root. What tool(s) should I use to create the sitemap, is there anything which can do it automatically as a cron job? Many thanks guys.
