UTM (PRO)

Show a different block depending on where the visitor came from. A UTM tag is a named set of query parameters; a block tied to one appears only when the address matches.

PageBlocks → Constructor → UTM.

A tag

Setting	What it does
Name	What you pick from the list when attaching a block
Parameters	The query parameters that must match
Order	Position in the list
Published	An unpublished tag matches nothing

A tag is only a name for a condition. Which visitor sees which block is decided where the block is attached to the page.

A block with no tag is always shown

Tagging is opt-in — an empty field is the normal case, not a missing setting. Reach for UTM only when a block genuinely differs by campaign: a headline for one ad group, a promo for one channel.

Create UTM tags and attach the necessary parameters to them.

Now, depending on the GET parameters, you will see the corresponding block.
