I'm considering using the canonical tag for the first time in a site, but can't find any information on what this does to your Analytics reports.
The likely setup is this:
There will be gallery pages for widgets. These will be filterable on the fly by users, and there will also be about 20 set filters as clickable links.
One way of avoiding dupes that I'm considering is the canonical tag, but what does this do to the data in Analytics? Can you see data for each individual filter, or is it all lumped together under the canonical url?
