LinkedIn Lead Gen Forms: Setup, Fields and What Works
. By Ads Daddy.
LinkedIn Lead Gen Forms let people raise their hand without leaving LinkedIn. They tap your ad, the form opens with their profile details already filled in, and they hit submit. No landing page. No typing on a tiny phone keyboard. That is why they convert. And it is also why a lazy form fills your CRM with people who barely remember clicking.
Getting the form built is the easy bit. Getting leads you can actually sell to is the game. If you would rather hand the whole thing to a team that runs LinkedIn ads every day, that is what we do. Otherwise, here is the full playbook.
TL;DR
- Lead Gen Forms are native forms attached to LinkedIn ads. Fields are pre-filled from the member's profile, which cuts effort and lifts conversion.
- You build them in Campaign Manager, then attach them to an ad in a campaign that uses the Lead generation objective.
- LinkedIn recommends five fields or fewer, even though up to 12 are allowed. Add up to three custom questions, ideally multiple choice.
- The form is only half the job. Speed of follow-up and a clean hand-off to your CRM decide whether leads turn into revenue.
- Match the offer in the ad to the form, and spell out the next step on the thank-you screen.

What LinkedIn Lead Gen Forms actually are
Think of a normal landing page as asking someone to fill in a visa application. A Lead Gen Form is a name badge: they already have one, they just hand it over.
LinkedIn describes them as forms pre-populated with members' profile data, which reduces the effort of filling them out and raises conversion rates. The form opens inside LinkedIn, so there is no page load and no drop-off between click and form.
They work with several ad formats. According to LinkedIn's own playbook, a form can be added to one or more ads and paired with Single Image, Carousel, Video and Message ads.
The reason B2B marketers love them: the profile data is the data you want. Job title, seniority, company, company size and industry arrive without the prospect typing a thing. If you are new to the platform itself, our guide to what LinkedIn advertising is covers the basics.
Lead Gen Form or landing page?
Both have a job. Pick by the offer.
| Situation | Lead Gen Form | Landing page |
|---|---|---|
| Low-friction offer (guide, webinar, demo request) | Strong fit | Fine, but more drop-off |
| Mobile-heavy audience | Strong fit | Slower, more typing |
| Offer needs a long sales pitch | Weak fit | Strong fit |
| You want full on-page tracking | Limited | Full control |
Rule of thumb: if the ask is small, keep it inside LinkedIn. If the offer needs persuading, send people to a page that does the persuading, then retarget the visitors.
How to set up a LinkedIn Lead Gen Form, step by step
Here is the process in Campaign Manager. Follow it in order and you avoid the usual stumbles.
1. Open the form library
In Campaign Manager, select your ad account and open Lead generation forms in the account assets area. Create a new form or pick an existing one, as outlined in this setup guide.
Where it goes wrong: building a fresh form for every ad. Keep a few templates (download, event, enquiry) and duplicate them.
2. Write the offer
You need an offer headline and details. Say what they get, in plain words. "Get the 2026 Aussie SaaS pricing report" beats "Download our resource".
3. Choose your fields
LinkedIn's playbook lists profile fields such as name, email, phone, location, job title, function, seniority, company, company size, industry, education and profile URL, plus up to three custom questions. It recommends five or fewer fields, though up to 12 are allowed.
More on this in the next section, because it is where most money is wasted.
4. Add your privacy policy and thank-you message
A privacy-policy URL is required. The thank-you message is not a throwaway. Use it to tell people exactly what happens next: a call within one business day, a download link, a calendar invite.
5. Build the campaign
Create a campaign with the Lead generation objective, attach the form to your chosen ad and activate the form before launch. A form left inactive is a classic way to burn budget on clicks that go nowhere.
6. Decide where leads land
You can export responses from Campaign Manager or connect a CRM or marketing-automation workflow. Set this up before launch, not after the first 40 leads are sitting in a CSV going cold.
Which fields to use (and which to cut)
Every extra field is a small tax on completion. Pay only for what you will use.
A solid B2B starter form:
- First name, last name
- Work email
- Company name
- Job title
- One multiple-choice custom question (for example, monthly ad spend range)
That is six items, but the profile fields are pre-filled, so the member only reviews them. LinkedIn also suggests that when you need custom questions to qualify, keep them to a minimum and consider multiple choice, as people are more likely to pick an answer than write one.
Cut:
- Phone number, unless your team really calls within the hour
- Anything you cannot name a use for
- Open text questions that nobody reads
A good test: for each field, finish the sentence "We use this to...". If you cannot, delete it.
Match the ad to the form
The ad makes a promise. The form must keep it. LinkedIn recommends matching ad and form content, clearly communicating the value and using the confirmation message to give next steps.
It is like a dating profile. If the photo says one thing and the first date says another, there is no second date.
Three offer types that tend to suit B2B:
- Content download. Promote a report or checklist. LinkedIn's playbook warns that the asset is not delivered automatically, so link it directly from the confirmation page.
- Event registration. Use the form to register people for a webinar or event.
- Service enquiry. Offer a demo, quote or interest form, and use the thank-you step to point to the next action, such as booking a time.
Targeting: who sees the form matters more than the form
A brilliant form shown to the wrong crowd is still a bad result. LinkedIn lets you target by factors such as job title, function, seniority, company size, industry and more, and each can be used to include or exclude, as GetResponse's guide notes.
Two habits pay off:
- Start narrow. Pick the job titles who sign off on your service, not everyone with "manager" in the title.
- Retarget warm people. Matched Audiences let you re-reach website visitors or contact lists. Our guide to LinkedIn Matched Audiences walks through setup and the mistakes to dodge.
One advertiser example reported by Zapier saw a 40% lift in completion and a 25% drop in cost per lead after retargeting site visitors with a short form. It is one example, not a promise, but it shows why warm audiences deserve their own campaign.
What happens after the click
This is where most campaigns quietly die. The lead arrives. Nobody calls. Three days later, it is a stranger.
There are three ways to get leads out of LinkedIn, as PPC Land describes:
- Download a CSV from Campaign Manager.
- Use a native CRM or marketing-automation integration (Salesforce, HubSpot, Marketo, Eloqua, Dynamics 365).
- Use LinkedIn's Lead Sync API or a connector for custom set-ups.
CSV is fine for a pilot. Past that, connect a CRM so leads arrive in seconds, not on Monday.
Then decide, before you launch:
- Who owns the follow-up?
- How fast do they respond? LinkedIn's playbook itself says to follow up promptly.
- What does a hot lead trigger, and what does a lukewarm one get?
Lead nurturing is its own discipline, and this explainer on nurturing strategies is a good primer on sequencing follow-up. For the wider system around it, see our lead generation workflow.
On the experience side, native forms keep friction low in the same way messaging-based flows do. If you are curious how that plays out on another channel, Messenger lead automation shows the same idea of removing steps between interest and enquiry.
Five mistakes that cost you leads
- Too many fields. Past five, completion tends to fall. Trim.
- Vague offer. "Contact us" is not an offer.
- No follow-up owner. Leads without a name next to them go cold.
- Mismatch between ad and form. Promise a guide, then ask for a sales call. Bounce.
- Judging by cost per lead alone. A cheap lead that never answers is expensive. Track cost per qualified lead and cost per customer. Always loop back to ROI.
Why hand this to a team
LinkedIn is not the cheapest channel, and mistakes show up fast on the invoice. A form, an audience, an offer, a CRM connection and a follow-up routine all have to line up. Miss one and the others cannot save it.
AdsDaddy creates, manages and optimises campaigns across LinkedIn, Meta, Google, YouTube and Microsoft, with integrated tracking and lead delivery, so you never need to learn the ad platform yourself. Our LinkedIn advertising workflow for Aussie businesses shows how we structure it.

Our take
Most businesses treat the form as the strategy. It is not. It is the doorway.
What decides results is everything around it: a tight audience, an offer people actually want, a short form and a team that answers quickly. We build campaigns as one system, from ad to tracking to lead delivery, because a great ad feeding a broken hand-off is just an expensive way to feel busy.
Our aim is simple. You run the business. We run the ads, and you get leads your sales team is glad to receive.
