Has anyone boosted signups by making their landing page longer instead of short and punchy?

Every CRO guide told us to keep our hero section clean, concise, and minimal. We had a super short landing page with just a bold headline and a CTA button, but conversion stayed stuck at 2%.

We decided to do the exact opposite: we rebuilt the page into a 3,000-word long-form teardown showing the exact step by step workflow real screenshots and edge case limitations. Conversions jumped to 5.4%.

It turns out high-intent buyers wanted deep clarity, not slick marketing buzzwords.
