The lesson
Gate a real internal document, and make the page sell it by listing three specific things inside the download.
The headline is "Get Rippling's $225M board deck". Beside a preview of a bar chart slide, a card titled "In this download, you'll get:" lists Rippling's board meeting KPIs, custom-built sales metrics and an "hourglass of cash" runway diagram, above a work email field and an orange "Download now" button.
Don't promise a document you can't back with a real figure or real internal material. Keep the title that states the outcome and the short itemized list of what's inside.
