The Lead Gen Form ad set shows a much higher conversion rate than the website ad set. The usual conclusion is that the landing page is broken.
Those percentages are not the same event. One counts an in-app prefilled submit. The other counts a click off LinkedIn, a page load, a site form, and an Insight Tag that has to fire.
Use Lead Gen Forms for a short capture. Use a landing page when the site must qualify, deliver a file, or collect fields the native form cannot. Compare pipeline, not the two Campaign Manager rates.
The two rates are not the same conversion
The lead generation objective shows a native form after the click. LinkedIn's lead generation objective help says that form is pre-filled with profile data. The conversion is the form submit inside LinkedIn.
The website conversions objective is a different funnel. LinkedIn's website conversions help is for actions you define on your site.
Conversion tracking has to be on. The Insight Tag, or a weaker image pixel, has to see the thank-you page or the event.
A native form rate sitting far above a website rate does not prove the page is several times worse. It often proves the site lost people in the hop, or the tag never fired. Do not treat those two columns as a creative test until both events mean the same CRM lead.
Lead Gen Forms have no extra fee beyond the ad set. They also have no cost-per-lead bid.
Purchase is still click or impression. A cheaper CPL in the export is math after the fact, not a bid type LinkedIn sells for this format.
Why the native form usually looks higher
Friction is the honest reason the rate jumps. The member stays on LinkedIn. Fields fill from the profile.
There is no new domain, no cookie prompt, and no mobile in-app browser fighting the tag.
Prefill and a short form
LinkedIn's Lead Gen Forms help calls this dynamic prefill. Contact and profile fields populate when the member hits the call to action.
Gender is not prefilled. Work email, work phone, personal email, personal phone, and empty profile fields can still be edited.
You can pick up to 12 fields, plus up to three custom questions that count toward that 12. Custom questions are required.
LinkedIn's own best practice is three to four fields. Fewer than the maximum will likely improve conversion rates. High form opens with few submits is a signal to cut fields, not to rebuild the site yet.
Validate work email if quality matters more than volume. That setting blocks common free domains on the work email field.
It does not catch every personal domain. Submission rates can fall when the member will not give a work address.
Multiple-choice custom questions pre-select the first answer. That can pad submits with a choice nobody picked. Treat those answers as weaker than a site form where nothing is ticked by default.
Desktop clicks that never open the form
On a single image ad, intro text does not always open the form. LinkedIn says mobile taps on the intro text open the Lead Gen Form, while desktop clicks on that intro text go to the landing page URL in the copy.
A mixed device report can hide that split. Desktop "conversion rate" for a Lead Gen Form ad set can be pulled down by people who never saw the form. Put the destination URL in the copy only when that desktop hop is intended.
When a landing page is still the better capture
A higher native submit rate is not a better lead. Profile email can be personal. Prefill can be stale.
Sales still has to call. Use the website when the capture needs work the form cannot do.
- The offer is a file or login that LinkedIn will not email for you after submit.
- The site must qualify with a calculator, pricing, or more than 12 fields.
- Legal needs consent the privacy policy URL and optional checkboxes cannot cover.
- The sale happens on your domain, and the Insight Tag is already measuring that event.
LinkedIn will not send the white paper for you. If the goal is to deliver content, put an ungated link in the thank-you message, or email the file after you download the leads.
A confirmation landing page after submit is allowed. That is a follow-up, not a replacement for the native form.
Website conversion rate also lies when the tag is late, blocked, or only on desktop. Image pixels are less accurate than the Insight Tag. Fix measurement before you kill a page that is actually converting in the CRM.
Choosing native capture versus a site form without mixing the two rates is part of performance marketing work. For a look at whether the current Lead Gen Form or website campaign is the one worth scaling, start with Get Free Assessment.
If this post is wrong, outdated, or you would take a different path
I write from work I have done on real sites. Search products change, and a step that was right when I published can go stale. I can also be wrong about the method.
If you disagree with the approach, the facts, or the outcome, I want the detail. Tell me what is off, what you would do instead, and where you saw it. I use that to correct the post so the next reader is not stuck.
