I will do some testing on my local machine with the IIS SEO toolkit and try to resolve some of these for the next release of Event Calendar Pro.

Probably some of the solution is going to involve adding noindex/follow meta tags on some of the view pages like week view and day view  so that search engines won't try to index them.

The reason these things give violations is because they appear to have the same content on different urls anf this is what causes the canonical warnings. For example the content on day view and week view is identical for every empty day or empty week. Since these views really just provide links to the details they have no seo value for them to be indexed, really you only want the detail views indexed.

You definitely do not want multiple pages to have the same meta description (that would produce more warnings) and don't really need meta descriptions at all on the pages that don't need to be indexed such as week view and dayview and monthview. Only the detail pages need descriptions and the main page where ECP is loaded you can put meta description in page settings. On the event details you can already add meta descriptions but they should be unique for each event.

You could do that since the detail pages use friendly urls.

robots.txt will only be read from the root of the web site. If its multiple sites based on host name they will all work the same. If its folder based child sites you could update the robots.txt file in the root for each site like

Disallow: /foldername/Events/

Keep in mind that if you are customizing robots.txt you need to be careful during upgrades because we ship a robots.txt file that would overwrite your custom one. So you would want to remove ours from the package before upgrading.

Best,

Joe
