Learning Objective
By the end of this guide, you'll know how to install the lemlist Website Visitors tracking script on your website (any platform) to identify companies visiting your website.
Why This Matters
The Website Visitors feature reveals which companies are visiting your website—even if they don't fill out a form. This lets you proactively reach out to interested prospects showing high-intent signals.
Prerequisites
Before you start:
Active lemlist account
Admin/editor access to your website (or to the tool managing your website header, such as your CMS, website builder, or tag manager)
Your website URL
How It Works
Once installed on your website, the tracking script helps identify companies visiting your pages. lemlist then displays these companies in Signals so you can filter them and add them to campaigns.
Note: It may take a few hours to identify the first visitors. You'll receive an in-app notification once visitors are detected.
Install Tracking Script
Step 1: Generate tracking script in lemlist
Go to Signals, open the Watchlists tab, then click New watchlist
In the New watchlist flow, select the Website visitors signal and, in Website visitor set up, enter your website URL, copy the JavaScript tracking code, confirm you’ve pasted it on your website, then click Next
Use format:
https://www.mywebsite.com
Step 2: Install the tracking script on your website
Add the copied JavaScript tracking code to your website so it loads on every page.
Open your website’s admin area (or your tag manager) and locate where you can add code site-wide (often called Header, Custom code, Head, or Tracking).
Paste the lemlist tracking code in the <head> section so it loads on every page.
Save/publish your changes.
Tip: If you use a tag manager, add the code as a Custom HTML tag and set it to fire on All pages.
View Website Visitors
Step 3: View tracked leads in lemlist
Go to Signals in lemlist.
Wait for tracked leads to be detected and displayed in the Signals list.
To focus on Website Visitors only, open the relevant Website visitors watchlist (or use the signal type filtering available in Signals).
✅ Result: Your tracked website visitors will appear in the Signals section, where you can review the visiting companies and associated lead information.
Best Practices
Target the right people - Focus on individuals within visiting companies who match your Ideal Customer Persona. Use high-intent signals to personalize your multichannel outreach.
Let tracking run - Give the system a few hours to identify first visitors before expecting results.
Combine with other data - Use website visitor data alongside other signals (LinkedIn activity, email engagement) for warmer outreach.
What Happens Next
Identification timing: First visitors may take a few hours to appear. You'll receive an in-app notification when visitors are identified.
How to use: Add website visitors to campaigns for targeted outreach based on their demonstrated interest.
Troubleshooting
No visitors appearing after 24 hours
Fix:
Confirm the tracking code is installed on your live website (not just in a draft/unpublished state) and is set to load on all pages.
Verify you pasted the full code exactly as provided by lemlist (no extra characters removed).
Check the website URL format in lemlist (must include
https://www.).Ensure the website receives traffic.
Changes not taking effect on the website
Fix: Clear any caching layers (CMS cache, CDN cache) and confirm you have the required permissions to edit your website header/custom code settings.
