[GTM glossary](/glossary.txt) Website visitor identification Signals & Intent # Website visitor identification In short Website visitor identification is the process of working out who is behind anonymous website traffic. Most often it resolves a visit to a company, using signals such as the network address. In some cases it resolves to a named person, usually when they have already identified themselves. It turns a website from a source of aggregate traffic numbers into a source of account-level leads. It is a first-party intent signal, because the behavior happens on your own properties. ## How identification works ### Company-level identification A visit is matched to a company, often by mapping the network address to an organization. It works best for office networks and is weaker for remote workers, mobile users, and VPNs. ### Person-level identification A visitor is matched to a named individual, usually after they fill a form, click a tracked email link, or sign in. Anything beyond that depends on the tool and on local privacy rules. --- ## What to do with identified visitors * **Filter by fit:** Compare identified companies with your ICP before anyone acts. * **Read the behavior:** A pricing or integration page visit says more than a blog view. * **Route fast:** Send hot accounts to the owning rep, or to an SDR if the account is unowned. * **Find the contact:** Look up relevant people at the account and reach out with a message that fits the page they viewed. --- ## Example Say a target account is identified visiting the security page and a case study in one day. An alert reaches the account owner, who writes to the head of IT with a note on security practices. This is more useful than a generic cold email because it follows real interest. --- ## Limits and privacy Identification is probabilistic, so expect gaps and some wrong matches. Treat it as a hint and verify before acting. Privacy laws such as GDPR and CCPA can affect how visitor data is collected and used, including consent and notices. This is general information, not legal advice, so involve legal counsel when setting it up. --- ## Identification vs. tracking Identification answers who visited. Website visitor tracking records what visitors do. Most teams need both to judge interest. --- ## Website visitor identification FAQs **What is website visitor identification?** Website visitor identification is the process of finding out which companies, and sometimes which individuals, are behind anonymous traffic on your website.
