How it works
How VisitLead recognizes a company, and never a person.
It all comes down to 4 parts: a tag, a collector that forgets the IP address, a resolver that reads public registries, and signals to your team.
01 · The tag
One line, under 6 KB.
The tag loads asynchronously, with no dependencies. If it does not respond, your site works as usual. It also follows single-page apps (URL changes without a reload).
<script async
src="https://visitlead.io/t.js"
data-site="K7Q2M9XW4RPA8DLE"></script>What it sends
- The page URL, without its parameters (except utm_*)
- The page title and the referring domain
- Screen size, language and consent status
What it never sends
- Form fields other than email and name
- A password, page content or keystrokes
- Anything at all if the visitor has opted out (#visitlead-optout)
02 · The network
The IP is used for a split second, then it is gone.
On every page view, the collector (hosted in Frankfurt) looks up who owns the network in the public internet registries (RIPE NCC, ARIN, APNIC, LACNIC, AFRINIC), then forgets the address. It is never written to a database or a log.
Kept
- Companies, schools and public bodies, with their domain and city
- For Switzerland, the commercial register entry (UID, legal form, municipality)
Left out
- Internet providers and mobile carriers: the visit stays anonymous
- Hosting providers and bots: counted separately, never shown as companies
To group the pages of a visit without a cookie, VisitLead computes a daily fingerprint with a secret that changes every day and is deleted after 48 hours. Two days can never be linked.
03 · Known contacts
Only people you already know.
VisitLead never guesses who a person is. A contact is recognized only if they have already given you their address, and only where the law allows it.
Newsletter link
Your Brevo or Mailchimp links carry a ?vl= token unique to each subscriber. The tag reads it, then removes it from the URL.
Website form
When a contact form is submitted, the tag keeps the email and name. Never the other fields.
Import and ScanLead
A CSV file of your clients, or business cards scanned with ScanLead.
04 · Signals
Where your team already works.
Monday digest
The week's 10 most interested companies and returning contacts, at 8 am in your time zone.
Instant alert
A known contact on an important page (pricing, quote request): an email right away.
Slack and webhooks
Every signal to Slack, Zapier, Make or your CRM, signed (X-VisitLead-Signature header) with 3 retries.
05 · Setup
4 steps, 2 minutes.
