Hi,
the manual for the old version can be downloaded here:

www.selfget.com/downloads/file/10-tagmeta-quickguide-j15.html

I am working on new online version for both ReDJ and Tag Meta. The Tag Meta version is available here:

www.selfget.com/documentation/tagmeta-joomla25.html

Unfortnately is not complete yet (I am still working on it and I hope to finish before the next week). Meanwhile, feel free to ask me anything about the features not documented yet.

But I don't understand the problem when you say:

Also when I insert a rule in the canonical link that creates him back without dominio.it/ but if I insert {siteurl}/paginacanonical considers that it should be wrong because it is considered subpage (/dominio.it/paginacanonical)

Can you post the rule?

Thanks,
Luigi

No, is clear.
The field "canonical" in the rule must be a full URL (with http) but can be built using macros too.

As example, suppose you have a lot of pages with ?view=skills and you want to define the canonical without this parameter for all of them. You don't need to create a rule for each URL, if you can match them all with a single regular expression (e.g. they all have a common pattern like /category/) you can build a single rule and use macros to build the canonical as follow:

In the last tab of rule edit screen you have a list of all available macros, take a look at it.

Kind regards,
Luigi

In this case it is not necessary, I just wanted to show you how to use another macro (this macro allows to drop variables from the origina URL, so in your case returns an empty string).

Kind regards,
Luigi
