Why most of your website visitors stay anonymous
Alex, founder of Knownly · · 5 min read
Install any visitor identification tool and you'll hit the same moment. Your analytics shows thousands of visitors this month, and the company list fits on one screen.
Nothing's broken. Most visitors can't be tied to a company from their IP address. Here's where they go.
Home and mobile internet
This is the big one. Someone reading your site from their kitchen is on Swisscom, Sunrise, Comcast or BT. Their IP belongs to the internet provider, and it gets shared with other households over time.
Mobile is the same, often worse. Carriers put lots of phones behind the same public IP (it's called carrier-grade NAT), so one address can be hundreds of people at once.
Hybrid work made this bigger. The person researching tools for their team might do it from home on Tuesday and from the office on Wednesday. Only Wednesday is visible.
Cloud security services
Plenty of companies route their staff's web traffic through a cloud security service like Zscaler or Cloudflare. Good for security. Bad for identification: the IP belongs to the security provider, so the visit looks like it came from a data centre.
VPNs, proxies and Tor
Consumer VPNs hide the real IP on purpose. A good tool drops these, because the "company" it would show you is the VPN provider.
Bots
A big chunk of traffic is automated: search crawlers, SEO tools, uptime monitors, AI crawlers, scrapers. Many run from cloud servers. Your analytics filters some of them. A visitor ID tool should filter more, because a script running on AWS will never buy anything.
What's left
The visitors you can identify are the ones on a company's own network: people in the office, or on a corporate VPN that exits through the company's own IPs.
That's a minority of your traffic. How big a minority depends on your audience. A site selling to enterprises with large offices will see more. A site that gets lots of mobile or social traffic will see less.
Reading match-rate claims
Some vendors advertise identifying up to 45% of the companies visiting your site. Before comparing numbers, ask what's being counted.
- Companies or visits? "45% of companies" and "45% of visitors" are very different numbers.
- Do internet providers count as matches? If they do, the rate goes up and the list gets worse.
- Where does the extra data come from? Some tools go beyond IP data, for example with cookies, data pooled across customers, or contact databases. That can raise the rate. It also changes the privacy picture.
The fair way to test a tool: install it for 2 weeks and read the list. Would you actually follow up with these companies?
How to use a partial list
You won't see everyone, and that's fine. Treat the list as a signal.
- A company that comes back 3 times in a week and reads your pricing page is worth a message.
- A spike in visits from one industry after a campaign tells you the campaign reached the right people.
- An existing customer reading your docs tells your account manager something too.
That's what Knownly is built for: a short list of companies that are actually on your site, with the pages they read and an intent score, so you know where to look first.
