I use WordPress Multisite as the CMS for a university website - each office has its own sub-site (using directories, not subdomains), but they are all part of the overall university site that I want google to map. There are generally only 10-30 pages per sub-site.
Can this tool--or any other--provide a single sitemap for a network of sites so that I can Google Search university-wide? Or is this not necessary, and something that could be handled with a tricked-out robots.txt?
Any help much appreciated.
