6 Lead Gen Enrichment Tools That Turn Anonymous Visitors Into Leads in 2026
98% of website visitors leave without filling out a form. These six enrichment tools identify who they are — turning anonymous traffic into actionable leads your sales team can contact.
In 2026, most B2B websites convert less than 2% of visitors into known leads. The other 98% leave anonymously — often after browsing your pricing page, case studies, or product documentation. Enrichment tools with visitor identification capabilities can reveal which companies are visiting your site and enrich those signals into actionable leads.
We tested six enrichment tools that support lead generation through visitor identification, form enrichment, and lead data enrichment. Here are the ones that actually turn anonymous website traffic into pipeline.
