Multiple rules can be applied together, so if more than a single rule matches with the current URL, these are applied in cascade using the ordering set, except if a rule is declared as ‘last one’ (in this case the process stop).

And that’s not all. Tag Meta comes with support for macros. This means that meta information can be generated dynamically for each page.

To allow complex transformations for data to use as meta info there are the placeholders. Placeholders allow you to define a set of values where each value is associated and identified by a name and is used in the definition of other placeholders or in the definition of meta info (practically they are based on the same principle of the variables in programming languages).

With support for link 'canonical' it is possible to specify the preferred version of a set of pages with highly similar content. But there is still other, Tag Meta comes with support for an ontology database of synonyms, that allows to automatically generate and add new synonyms of existing keywords in any page.

The plugin, finally, has some useful options to set custom global information like Generator, Author, Copyright, or to set and align the tag ‘title’ and the meta tag ‘title’ in many ways.
