Lead Gen Form (LGF)
Lead Gen Form (LGF) explained — in-platform forms with pre-filled data. ~6.1% CVR on LinkedIn in 2026, ~5x landing pages.

Updated July 2026.
A native ad format (LinkedIn, Meta) that opens a pre-filled form inside the platform when a user clicks, capturing leads without sending them to an external landing page.
Benchmark range
LinkedIn’s own (older) internal figure puts Lead Gen Form conversion around ~13% — roughly 5x off-platform landing pages (LinkedIn internal, treat as directional) — and practitioners consistently report meaningful CPL reductions. Meta Instant Forms perform similarly.
Why it matters
Removing the friction of typing details on a landing page dramatically lifts conversion. The trade-off is lower intent, so qualify and follow up fast.
2026 update
In 2026 in-platform forms gained extra value because they keep users on-platform and feed cleaner first-party signal to the Conversions API — useful as cookies fade. Connect forms directly to your CRM for instant follow-up, since speed-to-lead drives close rates.
