If you want to see who has visited a particular page, you'll need to do two things:
1) Add the tag to the page in the site dashboard
2) Make a stream to see the visitors with the tag
Add a tag to the particular page
Go to the "Site Tagging - Individual"
Paste in the URL you are wanting to tag, click Search.
CANDDi will bring that URL up on top of the list and to its right you will need to click edit page which brings up the following view.
Select the Tags tab and then add tag, type in what you want to tag visitors, click the green tick to add it
Then "Update Page".
Now your contacts who visit the page will be tagged. :)
Make a stream to show everyone with this tag.
Choose Contact, Tags, With the selected tag, *yourtag*
(If you don't see your tag in the dropdown, refresh the page and try again)
Then click "Add Rule Below" (you can then add other rules, e.g. if you want to only show the visitors who also have the tag "Identified"). Once you've added all the rules you want, click "Preview & Save"
Then choose the name of the stream, and create/add it to a Group (or 'dropdown') to organise your streams.
Now save it, and you're done - refresh to see the results :)
It will show everyone who has visited the page in the past, and continue to show people who visit in the future. Call if you need, on 0161 414 1080 or email firstname.lastname@example.org
