Yes. Sometimes, some teams, services or products make use of the ability to do custom meta-tags on their HTML code.
For example, one could use one or any of the following:
<meta name="google-analytics" content="your_id"/>
<meta name="disqus" content="your_id"/>
<meta name="uservoice" content="your_id"/>
<meta name="mixpanel" content="your_id"/>
for the several services you might be using under your property. If there's no specific or predefined meta-tag, you can still automate content based on a custom tag.
Imagine that your run website XYZ and you've always used the tag "XYZ_author" to identify the author of an article.
You may create a rule to automatically post on your Facebook Page all the articles created by John Doe after they're published, by using the settings:
- Method: Include only if
- Meta-type: Name
- Meta-value: XYZ_author
- Condition: contains (or is equal to)
- Condition-value: John Doe
