Open the form you want the advertorial to feed and switch to the Advertorials tab.
Click Create Advertorial and give it a name.
Choose Template (pre-filled with sample content for every block type, selected by default) or Blank (start from scratch).
Click Create. You land in the advertorial builder.
The builder has three panels. The left panel has two tabs: Blocks (your list of content blocks with a count badge, drag handles to reorder, and a trash icon to delete each block, plus an Add Block button at the bottom) and Theme (colours and fonts for the whole advertorial). The center panel is a live preview of the advertorial exactly as visitors will see it. The right panel has three tabs: Content (edit the selected block's fields), Typography (heading and body font settings), and Settings.
The Settings tab on the right panel has two sections. Navbar Button lets you customise the sticky CTA button that appears in the advertorial's navbar: set the Button Text (default 'Free Check'), Button Color, Button Size (Extra Small, Small, Default, Large), and Font Weight. Redirect Parameters lets you add an optional query string (e.g. utm_source=facebook&utm_campaign=spring) that is appended to the form URL when the navbar button is clicked — useful for attributing advertorial traffic within the form's analytics.
Advertorials are built from blocks you add, reorder by dragging, and remove from the Blocks tab. Available block types: Headline, Subheadline, Body, Image, Highlight Box, Blockquote, CTA Button, Button Grid, Tile Grid, Chip Grid, Numbered List, Icon Grid, Video CTA, Divider, Spacer, Table, Accordion, Testimonial, Comparison Chart, Pricing Card, Countdown Timer, Social Proof, Stats Counter, Embed, and Gallery.
Once saved, the advertorial is reachable at /f/<form-slug>/advs/<advertorial-slug>. UTM parameters on that URL are captured and flow through to any submission that starts from the advertorial's CTA.
