Using Clearbit Data to Personalize Webflow Landing Pages

Turn anonymous traffic into customized, high-converting user experiences.

If you use Webflow to build high-performing landing pages, you’ve probably asked yourself:

“How can I personalize this page for every visitor  without asking them to fill out a long form?”

‍

The answer: Clearbit.

‍

Clearbit helps you identify anonymous visitors based on their IP address and enriches that data in real time, allowing you to dynamically customize your Webflow site based on company, industry, location, or even company size.

‍

In this post, we’ll explore how to use Clearbit with Webflow to increase engagement and conversions through smart, privacy-friendly personalization.

‍

Why personalization matters?

‍

Generic landing pages are fine. But personalized landing pages?

‍

They convert significantly better.80% of customers are more likely to buy from brands that offer personalized experiences

Personalized headlines and calls to action can increase conversions by 30–50%.You can show the right message to the right person at the right time automatically.With Clearbit, you can personalize based on company data, without requiring the visitor to sign up or fill out anything.

‍

How Clearbit Works?

‍

Clearbit Reveal uses reverse IP lookup to match visitors to their company (and related data), such as:

• Company name
• Industry
• Location
• Number of employees
• Technology stack
• Revenue size

This data can be downloaded in real time and injected into your Webflow page via JavaScript.

‍

Here are some ways you can personalize landing pages in Webflow using Clearbit:

1. Dynamic company name in headlines
Instead of:

“All-in-one platform for your team”

You can display:

“All-in-one platform for teams at Stripe”

‍

2. Custom calls to action based on industry

<script>

 async function getCompanyData() {

   const res = await fetch('https://reveal.clearbit.com/v1/companies/reveal', {

     headers: {

       'Authorization': 'Bearer YOUR_CLEARBIT_API_KEY'

     }

   });

   if (!res.ok) return;

   const data = await res.json();

   if (data && data.company && data.company.name) {

     document.querySelectorAll('.company-name').forEach(el => {

       el.textContent = data.company.name;

     });

   }

   // Example: show industry-specific block

   if (data.company.industry === 'Financial Services') {

     document.querySelector('.cta-finance')?.classList.remove('hidden');

   } else {

     document.querySelector('.cta-general')?.classList.remove('hidden');

   }

 }

 getCompanyData();

</script>

Fintech companies → “Download your compliance checklist”

SaaS companies → “Launch faster with scalable infrastructure”

Ecommerce brands → “Increase sales with smarter ad funnels”

‍

3. Geo-targeted content

Show different recommendations, visuals, or language variants based on the user’s region or country.

‍

How to implement it in Webflow?

‍

Step 1: Sign up for Clearbit Reveal

You will receive an API key and documentation on using their JavaScript snippet.

‍

Step 2: Add the Clearbit script to Webflow

Go to your Webflow project settings → Custom Code → Footer

‍

You have replaced "YOUR_CLEARBIT_API_KEY" with your actual key

You have added span or div elements with classes like .company-name, .cta-finance, etc.

‍

Step 3: Create conditional blocks in Webflow

In Webflow Designer:

• Use elements with class names that match your JavaScript targeting (e.g. .cta-finance, .cta-saas)
• Set them to hidden by default
• Let the script decide what to display based on Clearbit data

‍

Is this privacy-friendly?

‍

Yes. Clearbit Reveal uses company-level data, not individual personal data. It works best for B2B use cases and is GDPR-compliant when implemented correctly.

However, always display the privacy notice and review Clearbit’s compliance documentation for best practices.

‍

Webflow gives you the power to design beautiful landing pages. Clearbit gives you the data to make them smarter.

Together, they allow you to build experiences that speak directly to your audience - without overwhelming your development team or adding extra content to your stack.
