How to Set Up a LinkedIn Lead Gen Form: Step by Step

A LinkedIn Lead Gen Form is a sign-up form created in Campaign Manager with the "Lead generation" objective. It is automatically pre-filled with the user's LinkedIn profile information. Setup takes seven steps: choosing the campaign objective, defining the target audience, selecting the ad format, building the form, preparing the ad creative, setting the budget and bid, and sending incoming leads to your CRM. Users can submit their details in two clicks without leaving the ad, so the form creates far less friction than traditional flows that send people to a website form, especially on mobile.

For B2B companies, the real challenge isn't getting the form live. It's collecting the right information from the right people and getting it to the sales team quickly. In this article, we walk through Lead Gen Form setup step by step. Using concrete examples, we cover which fields to ask for, what to watch out for under KVKK (Turkey's Personal Data Protection Law), how to plan your budget, and what to do so leads don't fall through the cracks once they arrive.

What is a LinkedIn Lead Gen Form and why does it work in B2B?

In a traditional ad flow, the user clicks the ad, goes to your website, waits for the landing page to load, finds the form, and types in their name, email, company and job title one by one. You lose users at every one of these steps. The drop-off is even more pronounced on mobile, because nobody enjoys filling out forms on a small screen.

A Lead Gen Form shortens this flow. When the user clicks the call-to-action button in the ad (for example, "Download" or "Register"), a form opens inside LinkedIn. Fields such as first name, last name, email, company name and job title are pulled automatically from the user's profile. The user simply reviews the details and submits.

From a B2B perspective, there are three key advantages:

• Data quality: Because information such as job title, company and seniority comes from the user's profile, junk entries like "asdf" or fake names are reduced.
• Alignment between targeting and form data: If you showed the ad to an audience of "Procurement managers at manufacturing companies with 200+ employees," most of the people who fill out the form will genuinely match that profile.
• No dependence on your website: You can launch a campaign without building a landing page or waiting on your development team.

There is a downside too: because the form is so easy to fill out, you may also get low-intent leads. This needs to be balanced through form design and your follow-up process. We'll cover how to do that later in this article.

What do you need before you start?

Completing the checklist below before you begin setup will save you from dealing with half-finished campaigns in Campaign Manager.

1. A LinkedIn Company Page: Ads are published on behalf of a company page. Your page's logo, description and recent posts should be up to date. People who see your ad often take a look at your page as well.
2. A Campaign Manager account and payment method: You need to create an ad account and add a credit card. Billing details and currency should be set correctly from the start, because changing them later is a hassle.
3. Permissions: The person creating the form must have at least the "Campaign manager" role in the ad account. They also need the relevant permission on the company page.
4. A privacy policy URL: LinkedIn requires a privacy policy link for every Lead Gen Form. If you operate in Turkey, this page should also cover your KVKK privacy notice.
5. An offer: People don't fill out forms for nothing. You should have something concrete ready in return, such as a report, an industry checklist, a webinar registration, a free assessment or a demo.
6. Where leads will go: Will you set up a CRM integration, or will leads be downloaded manually? This decision should be made up front.

In corporate organizations, ad copy, form questions and privacy notices usually go through legal and marketing approval. If this process isn't well organized, campaigns can sit idle for weeks. You can apply the structure from our article on the B2B social media content approval process to your ad creatives as well.

Step 1: How should you choose the campaign group and objective?

In Campaign Manager, start by creating a campaign group. A campaign group is a folder that keeps related campaigns together. Give it a descriptive name, such as "2025 Q1 – Manufacturing Sector Report Download." You can also set a total budget and date range at the group level.

Next, create a new campaign within the group and select "Lead generation" as the objective. When you choose this objective, LinkedIn optimizes the campaign to show it to people who are most likely to fill out the form, and the Lead Gen Form option becomes available.

A common mistake here is creating a campaign with the "Website visits" objective and then trying to add a form. In that case, the form option won't appear. The objective determines the campaign's entire optimization logic, so it needs to be set correctly from the very beginning.

Naming tip: Include the objective, audience, format and offer in the campaign name. For example: `LG_Procurement_TR_SingleImage_ReportQ1`. A few months from now, when you're trying to figure out which of 15 campaigns is which, this discipline will save you time.

Step 2: How should you define your target audience?

The success of a Lead Gen Form depends largely on targeting. No matter how good the form itself is, an ad shown to the wrong people will bring in the wrong leads.

The core targeting layers for B2B are:

• Location: All of Turkey, or only Istanbul, Ankara and Izmir? Limit it to the regions you serve.
• Company attributes: Industry, company size (employee count range), specific company lists.
• Member attributes: Job title, job function, seniority, skills, groups.
• Matched audiences: You can upload your own customer or target account list to run account-based (ABM) targeting.

Let's look at a concrete example. Imagine a company that sells industrial automation solutions. Its audience definition might look like this:

• Location: Turkey
• Industry: Machinery manufacturing, automotive, food production
• Company size: 201–5,000 employees
• Job function: Operations, Engineering
• Seniority: Manager, Director, VP

This audience is narrow and focused enough. Still, make sure it doesn't fall below the minimum audience size LinkedIn recommends for the campaign to learn efficiently. If the audience is too small, you won't get impressions; if it's too large, your budget will be spent on irrelevant people.

We covered targeting options, how to combine layers and which combinations to avoid in detail in our article on B2B targeting in LinkedIn ads.

Tip: The "Audience Expansion" option may be turned on by default. If you're working with a narrow, well-defined B2B audience, we recommend turning it off. Otherwise, LinkedIn may also show your ad to people who are "similar" but not actually in your target audience.

Step 3: Which ad format should you choose?

Lead Gen Forms can be used with several formats. The most common options are:

• Single image ads: The quickest format to test. With a clear offer and a strong visual, it's a good starting point for most campaigns.
• Document ads: Extremely useful in B2B. Users can read the first few pages of a report in their feed and fill out the form to see the rest. This setup attracts people who "know what they're downloading," which results in higher-quality leads.
• Video ads: Useful when you need to tell a story, such as a product demo or customer story. The form is offered via the call-to-action button rather than at the end of the video.
• Carousel ads: Well suited to presenting multiple features or a step-by-step process.
• Conversation ads: Ads delivered to the inbox that progress through buttons with options. You can place the form within this flow.

To start, we recommend launching two formats with the same offer and the same form: for example, a single image ad and a document ad. After two to three weeks, you can compare which format delivers a lower cost per lead and higher-quality submissions.

Step 4: How do you create a Lead Gen Form?

You can create the form during campaign setup, or prepare it in advance under Account Assets > Lead gen forms. Preparing it in advance is more practical for companies with an approval process.

The form creation screen consists of several sections.

Form name and language

The form name is for you only; users won't see it. Give it a name consistent with your campaign naming, such as `Form_ReportQ1_Short`. Choose your target audience's language. In a Turkish-language campaign, the form should also be in Turkish.

Offer headline and details

The headline shown at the top of the form tells users why they should leave their details. LinkedIn applies character limits to these fields, so keep it short and clear.

Weak example: "Get in touch with us" Strong example: "7 Ways to Reduce Unplanned Downtime in Manufacturing – Free Report"

In the details field, describe what the offer contains in one or two sentences: "In this 24-page report, you'll find maintenance planning, sensor data usage and example scenarios."

What information should you ask for?

Here, LinkedIn offers fields auto-filled from profile data: first name, last name, email, phone, company name, job title, seniority, industry, company size, city, country and so on. You can also add your own custom questions.

The rule is simple: Every additional field lowers the form completion rate, but it may improve lead quality. Strike this balance based on the value of your offer:

• Top-of-funnel offers (report, checklist): 3–4 fields are enough. First name, last name, email, company name.
• Mid-funnel offers (webinar, case study): Add job title and company size.
• Bottom-of-funnel offers (demo, free assessment, quote request): Add phone and one or two qualifying questions.

One note: the email LinkedIn auto-fills is the email registered to the user's LinkedIn account, which is usually a personal address. If you want a work email, select the "Work email" field or add it as a separate question.

How should you structure custom questions?

Custom questions are the most effective way to qualify a lead before it reaches the sales team. Wherever possible, use multiple-choice rather than open-ended questions, because typing on mobile lowers completion rates and open answers are also harder to analyze.

Sample qualifying questions:

• "Are you looking for a solution in this area?" → Yes, within the next 3 months / Yes, within 6–12 months / I'm just researching for now
• "What method are you currently using?" → Manual tracking / Excel / An existing software tool / None
• "What is your role in the purchasing decision?" → Decision-maker / Influencer / User / Researcher

With these answers, the sales team can prioritize "decision-makers looking within 3 months" and move the others into an email nurturing flow.

Privacy policy and KVKK consent

LinkedIn requires a privacy policy URL. In addition, you can add optional custom consent checkboxes. If you're collecting data from people in Turkey, keep the following in mind:

• The privacy policy link should provide access to your privacy notice under KVKK.
• If you plan to send commercial electronic messages (marketing emails, SMS), add a separate consent checkbox for this. The checkbox must not be pre-ticked.
• The consent text should be plain: "I agree to receive emails about products and events."

For a definitive framework, we recommend working with your company's legal counsel. Having the text approved before the form goes live prevents the data you collect from becoming unusable later on.

Hidden fields

Hidden fields aren't visible to users but are added to every lead record. By entering information such as campaign name, source and offer type here, you can clearly see in your CRM where each lead came from. For example: `source=linkedin`, `campaign=report_q1`, `format=document`. This is one of the most overlooked yet most valuable settings for measurement.

Thank-you screen

After submitting the form, the user sees a thank-you message. You can add both a message and a link here. Two important points:

• Deliver the offer immediately. If you promised a report, the link should go straight to the report. Saying "We'll send it to your email" and making people wait a day cools their interest.
• Suggest a next step. For example: "Your report is ready. Would you like a free 20-minute assessment for your own facility?" along with a calendar link.

Step 5: How should you prepare the ad copy and visual?

However well your form is designed, it will never be opened if users don't stop when they see the ad. Key points for your ad creative:

• Intro text: The first 150 characters are critical, because the rest of the text is cut off with "…see more." State the problem and the offer in the first sentence. Example: "Unplanned downtime is quietly driving up your production costs. We've compiled 7 ways to manage maintenance planning with data in our free report."
• Visual: A mockup of the report cover, a clear headline and your brand colors are enough. Showing the offer itself works better than a stock photo.
• Headline: Repeat the offer in the headline below the visual.
• Call-to-action button (CTA): It should match the offer. "Download" for a report, "Register" for a webinar, "Request demo" for a demo.

Run at least 2–3 different creative variations in every campaign. You can highlight the problem in one, the outcome in another, and social proof (in general terms, for example "built for production managers in the industry") in the third.

Step 6: How do you set your budget and bidding strategy?

LinkedIn has higher click and lead costs than other platforms. In return, you reach a more clearly defined B2B audience. We recommend the following approach when planning your budget:

1. Work backward from your target number of leads. For example, if you're aiming for 40 leads a month and assume the cost per lead in your industry will be roughly $50–100, your monthly budget should be in the range of $2,000–4,000. These figures are only a sample calculation. Actual costs vary considerably by industry, audience and offer.
2. Leave room for the learning phase. Costs may be high in the first 1–2 weeks. Making frequent changes to the campaign during this period resets the learning.
3. Bidding strategy: Starting with "Maximum delivery" (automated bidding) and switching to a "Cost cap" strategy as data accumulates is a common and safe approach.
4. Daily or lifetime budget? For campaigns ending on a specific date (such as webinar registration), a lifetime budget is easier to control; for campaigns that collect leads continuously, a daily budget is.

We covered the factors that affect costs, budget planning and bid types in detail in our guide to LinkedIn advertising costs.

Step 7: How should you send leads to your CRM?

Submissions from Lead Gen Forms accumulate in Campaign Manager and can be downloaded as a CSV from there. However, leads remain downloadable on the platform only for a limited time (usually 90 days). More importantly, manual downloads cause delays of several days.

The recommended flow is:

• Native integration: Widely used CRM and marketing automation tools such as HubSpot and Salesforce have direct integrations with LinkedIn. Setup usually takes just a few minutes.
• Connector tools: If your CRM doesn't have a direct integration, you can use Zapier or similar automation tools to send leads to your CRM, a spreadsheet or a Slack channel.
• Field mapping: Test that every field in the form maps to the correct field in your CRM. Your hidden fields should be included in this mapping too.
• Test lead: Before launching the campaign, fill out the form in preview mode and confirm that the record lands in your CRM.

How many fields should a form have?

This is one of the most frequently asked questions, and there's no single right answer. Here's a practical framework:

| Offer type | Recommended number of fields | Example fields | |---|---|---| | Report / e-book | 3–4 | First name, last name, work email, company | | Webinar | 4–5 | + job title, company size | | Demo / assessment | 5–7 | + phone, 1–2 qualifying questions |

Monitor the form completion rate while the campaign is live. If a high share of people open the form but don't submit it, consider reducing the number of fields. If lead volume is high but the sales team says "none of them are a fit," add a qualifying question.

What should you do after a lead comes in?

The weakest link in Lead Gen Form campaigns is often not the form but what happens afterward. Many companies collect leads, but those leads sit in a spreadsheet, get called a week later, and the person doesn't even remember filling out the form.

A healthy follow-up process can be set up like this:

1. Instant automated email: As soon as the form is submitted, send an email containing the link to the offer and a brief introduction.
2. Qualification and routing: Split leads into "hot" and "nurture" groups based on their answers to the qualifying questions.
3. Fast contact: Ideally, reach out to hot leads within the same business day. A short, personal connection request from the sales rep on LinkedIn also works well alongside email.
4. Data enrichment: You can shorten the sales team's prep time by filling in missing details from the form submission, such as phone number, company website or company size, using B2B data tools like Apollo.io.
5. Nurturing flow: Add leads who aren't ready yet to a 4–6 week email series: a relevant case study, industry content, a webinar invitation.

Which metrics should you track?

Campaign Manager shows you a large number of metrics. For Lead Gen Form campaigns, these are the ones to focus on:

• Lead form open rate: The share of people who click the ad and open the form. If it's low, your ad creative or offer isn't capturing interest.
• Form completion rate: The share of people who open the form and submit it. If it's low, the form is too long or the questions are off-putting.
• Cost per lead (CPL): Total spend divided by the number of leads.
• Qualified lead rate: The share of leads the sales team marks as a "fit." This metric is measured in your CRM, not in Campaign Manager, and it's the most important one.
• Opportunities and closed-won deals: How many leads turned into sales opportunities, and how many became customers?

A campaign with a $40 cost per lead that never converts into sales is more expensive than one with a $120 cost per lead that consistently generates opportunities. When evaluating campaigns, you need to look all the way to the bottom of the funnel. You can learn how to make this connection in our article on how to measure B2B social media ROI.

What are the most common mistakes?

• A low-value offer: "Subscribe to our newsletter" or "Get in touch with us" is usually not a good enough reason to fill out a form.
• Settling for personal email: Because you didn't ask for a work email, the sales team ends up emailing personal Gmail addresses.
• Unnecessary fields: Don't ask for information you won't use. Every field cuts into your completion rate.
• Skipping hidden fields: A few months later, you won't know which lead came from which campaign.
• Slow follow-up: Leads sit in a spreadsheet for weeks.
• Premature optimization: Shutting down a campaign or overhauling the audience based on two days of data.
• Creative fatigue: Showing the same visual to the same narrow audience for months. Performance drops as frequency rises. Refresh your creatives at regular intervals.

Frequently asked questions

Is the LinkedIn Lead Gen Form paid?

Creating the form itself is free, but you need to run an ad campaign to get it in front of users. In other words, the cost comes from your ad budget, not the form. You pay based on impressions, clicks or an optimization goal, depending on the bid type you choose.

Is data collected with Lead Gen Forms KVKK-compliant?

LinkedIn's form infrastructure requires a privacy policy link, but KVKK compliance is the responsibility of the company collecting the data. It's recommended that your privacy notice be accessible from the privacy policy link and that you add a separate, unticked consent checkbox for marketing communications. For a definitive framework, you should work with your legal counsel.

How long can I download leads from Campaign Manager?

Leads remain downloadable in Campaign Manager for a limited time, usually 90 days. That's why you should download leads regularly or, better yet, transfer them automatically through a CRM integration. An integration both prevents data loss and enables the sales team to respond quickly.

Which is better: a Lead Gen Form or a landing page on your website?

Lead Gen Forms generally deliver higher completion rates and less friction, especially among mobile users. Landing pages, on the other hand, offer more room to tell your story and bring visitors to your website for retargeting. Many B2B companies test both with the same offer and decide based on lead quality.

Conclusion

The technical side of setting up a LinkedIn Lead Gen Form can be completed in a few hours. What really makes the difference is presenting a valuable offer to the right audience, designing the form to ask only for the information you truly need, and putting incoming leads in front of the sales team the same day. When you treat objective selection, targeting, format, form design, creative, budget and CRM integration as one interconnected system, Lead Gen Form campaigns become a steady, measurable source of sales opportunities.
