Website Identification FAQs
Does Happierleads have a Free trial?
What is Happierleads?
Happierleads is the only solution that enables you to identify, qualify, and engage with your anonymous B2B website visitors—all within a single tool. No additional licenses or integrations with other outreach automation tools are necessary.
Who typically uses Happierleads?
Happierleads is used by Sales, Growth, and Marketing teams across various industries. If you are a B2B company, we are the solution for you. Sales teams use the platform to turn anonymous traffic into opportunities and increase productivity. Marketers use the platform to automate lead generation and increase conversions.
How is this different from Clearbit, 6Sense, or DemandBase’s Website Identity Solutions?
Most companies rely on ‘Reverse IP Lookup’ technology to connect IP addresses with company names. At Happierleads, we use a completely different approach—our fully-permissioned, proprietary publisher network—allowing us to identify the exact individuals visiting your website. Discover more about how we identify your site visitors here.
Why is Happierleads ranked number #1 for data quality on G2 and Capterra?
Happierleads offers an advanced feature that automatically filters out bots, ISPs, and other non-qualifying traffic sources to ensure you receive only high-quality leads. Additionally, unlike other tools, Happierleads provides the flexibility for you to manually remove leads as needed.
What about U.S. state privacy laws, like the California CCPA and CPRA?
How accurate is the visitor identification?
Most reverse-IP tools only identify the company. We go further — using our permissioned publisher network we identify the exact person behind the visit and enrich them with verified work email and LinkedIn data. Match rates depend on traffic geography, but customers typically see person-level identification on 30–55% of B2B sessions and company-level on 80%+.
How long does setup take?
About 5 minutes. Sign up, paste a single tracking snippet into your site (or install our GTM template / WordPress plugin), and identified visitors start appearing in your dashboard within a few hours. No engineering project required.
What if my website doesn't get much traffic?
You don't need huge traffic to win — most of our customers have under 10,000 monthly visitors. Even on lower-traffic B2B sites a handful of identified buyers per week often pays for the tool many times over. You can also pair it with our 175M-contact database and outreach engine to build pipeline beyond just your site visitors.
Does it integrate with my CRM and outreach tools?
Yes. Push identified leads directly into HubSpot, Salesforce, Pipedrive, Zoho, GoHighLevel, Slack, or anything that supports Zapier and webhooks. CSV export is available on every plan, and our built-in email and LinkedIn outreach engine lets you act on identified visitors without leaving Happierleads.
