How to identify anonymous website visitors using Leadforensics features

If you work in B2B sales, marketing, or just want to know who’s poking around your website, you’ve probably run into a big frustration: most visitors don’t fill out forms or leave their info. They're ghosts. But what if you could figure out who they are—or at least which companies are interested—without relying on guesswork? That's where tools like Leadforensics come in.

This guide walks you through exactly how to use Leadforensics to identify those anonymous visitors, separate the signal from the noise, and actually do something useful with what you find. I’ll call out what works, what’s hype, and what you can safely ignore.


Who This Guide Is For

  • B2B marketers who need better lead sources
  • Sales teams sick of cold-calling with no context
  • Website owners curious if expensive traffic is actually worth it
  • Anyone who wants to stop flying blind and start seeing who’s behind the clicks

Step 1: Understand What Leadforensics Really Does (and Doesn’t)

Before you get excited, let’s be clear: Leadforensics does not tell you, “Bob Smith from Acme Inc. visited your pricing page at 2:17pm.” That sort of tracking is fantasy unless Bob is logged in or fills out a form.

What Leadforensics actually does: - It matches website visitor IP addresses to business-owned IP ranges. - It tells you which company or organization (sometimes just the ISP) visited, when, and what they looked at. - Sometimes, it suggests contact info for people at that company (pulled from public databases or LinkedIn).

It does not: - Identify individuals (unless they fill out a form). - Track home or mobile users accurately (most use dynamic IPs or VPNs). - Replace the need for good content and real lead nurturing.

Bottom line: If you want to know which companies are interested in your site, this is useful. If you want names, emails, and promises of intent, you’ll be disappointed.


Step 2: Set Up Leadforensics Tracking

You can’t identify anything if the tool isn’t set up right. Here’s how to get Leadforensics running:

  1. Sign up and log in. (Obvious, but worth saying.)
  2. Add your website. Leadforensics gives you a unique tracking script (like Google Analytics).
  3. Install the script.
  4. Paste it into the <head> section of your website, or use your CMS’s custom code option.
  5. If you use tag managers like Google Tag Manager, you can add it there.
  6. Check it’s working.
  7. Visit your site from a business network. You should see your visit show up in Leadforensics after a few minutes.
  8. Don’t panic if you see lots of “unknown” or “ISP” listings—more on that in a second.

Pro tip: The tool only works if the visitor is coming from a business IP. So if you’re testing from home or mobile, results may look underwhelming.


Step 3: Review the Data—What’s Actually Useful?

Leadforensics gives you a firehose of data: company names, pages viewed, time on site, repeat visits, even suggested contacts. Here’s how to separate what matters from the fluff:

Key Data Points Worth Your Time

  • Company Name: This is the big one. If you see “Acme Corp” or “BigBank PLC,” you know someone from there was interested.
  • Visit Details: Which pages did they look at? Did they spend five seconds or five minutes?
  • Repeat Visits: If the same company keeps coming back, that’s a genuine signal.
  • Suggested Contacts: Sometimes these are gold, sometimes just a random list of employees.

Data to Ignore (Mostly)

  • Generic ISPs: If it says "Comcast Business" or "BT," you’re out of luck. Could be anyone.
  • Contact Guesswork: Leadforensics tries to match company visitors to their employee directory. Don’t assume those people actually visited your site.
  • Intent Scores: These are often just pageview counts dressed up with fancy math. Use common sense.

Step 4: Filter and Qualify Your Visitors

Most of your “leads” will be junk. Here’s how to sort through them:

  1. Set up filters.
  2. Exclude ISPs, universities, and other non-targets.
  3. Focus on companies that fit your ideal customer profile (industry, size, region, etc.).
  4. Prioritize by behavior.
  5. Did they visit high-value pages (pricing, demo, contact)?
  6. Was it a quick bounce or did they dig in?
  7. Tag and score.
  8. Use Leadforensics’ tagging features to mark hot prospects, competitors, or partners.
  9. Don’t obsess over the software’s own scores—build your own simple criteria.

Pro tip: Don’t waste time chasing every single “lead.” 90% will go nowhere. Invest effort where the data actually lines up with your sales goals.


Step 5: Take Action—But Don’t Be Creepy

Now you’ve got a shortlist of companies showing real interest. Here’s what to do next:

Research

  • Look up the company on LinkedIn. Who’s in the right department? Who’s likely to care about your solution?
  • Check recent news or funding rounds—context is gold.

Outreach

  • Use a warm outreach approach. “I noticed your company has been exploring solutions like ours” is usually better than “I saw you on our website.”
  • If you use the suggested contacts, remember: they may not be the actual visitor. Treat them as starting points, not gospel.

Sync with Sales & Marketing

  • Feed good leads into your CRM.
  • Let your sales team know why you think the company is a fit (what pages they visited, repeat visits, etc.).
  • Don’t flood your team with junk—curate and quality-check.

What NOT to do: - Don’t email people saying, “I saw you were on our website.” It’s off-putting, and in some regions, it could raise privacy concerns. - Don’t buy into the fantasy that these are guaranteed sales opportunities. They’re clues, not contracts.


Step 6: Automate and Integrate (If It Saves You Time)

Leadforensics has integrations with CRMs like Salesforce, HubSpot, and others. These can save you time—if set up right.

  • Set up workflows to push only qualified leads into your CRM.
  • Don’t flood your sales reps with every company that visits. That’s a fast track to “lead fatigue.”
  • Regularly review what makes it from Leadforensics into your pipeline. Tweak filters as you go.

If you’re a small team: Don’t overcomplicate this. Manual review and Excel sheets work just fine until you’re drowning in data.


Step 7: Watch Out for Pitfalls and Hype

A few things marketers and sales teams often get wrong with Leadforensics:

  • Overestimating accuracy: Not every “identified company” is a perfect match. Sometimes it’s a shared office building, VPN, or third-party IT provider.
  • Thinking you’ve got intent: Just because someone visits your site doesn’t mean they’re ready to buy. They might be a competitor, a job seeker, or bored.
  • Privacy and compliance: Be careful with how you use and share this data, especially in Europe or regions with strict privacy laws.

Pro tip: Use Leadforensics as a clue generator, not a crystal ball. It’s one piece of the puzzle, not the answer to all your lead gen prayers.


What Actually Works (and What Doesn’t)

Works Well:

  • Spotting which companies are showing interest, especially big accounts.
  • Prioritizing outreach, so you’re not totally cold-calling.
  • Giving marketing and sales teams better context for follow-up.

Doesn’t Work (or Isn’t Worth Your Time):

  • Expecting personal info on individual visitors (unless they fill out a form).
  • Relying on the tool for consumer/B2C traffic—it’s a waste.
  • Blindly trusting the suggested contacts or intent scores.

Keep It Simple and Iterate

There’s a lot of noise in the world of “lead intelligence.” Tools like Leadforensics can pull back the curtain a bit, but they’re not magic. Start simple: set up tracking, look at the companies that matter, and act on real signals. Tweak your filters, ignore the hype, and focus on what’s actually helping you connect with real prospects.

The best results come from using this data as a nudge—not a shortcut. Keep things grounded, and you’ll avoid the classic lead gen headaches.
