Turtl Docs can be a powerful portal for lead capture. You can feature lead capture forms in your content, and tailor the way they appear based on your content and objectives.
You can set them as a hard-gate (mandatory form) or a soft-gate (optional form). Your choice will be impacted by how incentivised you anticipate your readers will be at that stage of the journey to swap their details for your content.
There is also flexibility around where you place the form. Do you want to allow your readers to digest some of the content first, before being presented the form? Or do you want to gate the entire Doc? Again, this will depend on the stage of the journey the reader is at, their motivations, and your content objectives.
