### [Leadpipe](https://www.g2.com/products/leadpipe-com-leadpipe/reviews)

Buyers are deciding now. We tell you who. Only 2% of the people on your site ever fill out a form. The other 98% research, compare, and decide — in silence. Leadpipe breaks that silence. We identify the real people visiting your site. Not just the company — the person. Name, role, company, LinkedIn, phone, email, and the exact pages they viewed. Your team reaches the buyer while they're still in-market, not weeks after they've moved on. Person-level, not company-level. Most tools tell you "someone from Acme stopped by." Leadpipe tells you it was the VP of Marketing, what she read, and how to reach her. By the numbers: - 35–40%+ match rate - 90%+ accuracy - 53+ data points per identified visitor On every visitor we resolve: - Position & seniority — know you're talking to a decision-maker - Firmographics — industry, size, location, and more - LinkedIn profile — engage where they already are - Direct phone & email — reach them without the guesswork - Pages viewed — see exactly what they came for Go beyond analytics. Stop guessing who's interested. Start with a name.

Updated October 3, 2024

Visitor Identification software is used by companies to profile the people who visit their websites, with the final goal of converting them into customers. Most website design and management solutions only offer statistics like the number of visitors, and number of visits, but no detailed information on the profile of website visitors. Visitor Identification software provides salespeople with the missing information from website visitors necessary to convert them into a lead. Marketers can also use Visitor Identification software to better target visitors with content.

To effectively use this type of software, salespeople and marketers need to work with web development teams to integrate visitor identification solutions into the company website. The information gathered by Visitor Identification software is used by sales and marketing departments and therefore needs to be transferred to CRM solutions as well.

To qualify as a Visitor Identification software, a solution must:

- Collect visitor information, like company and contact information, which can be managed using lists
- Include metrics such as the frequency of the visits, time spent on the website, as well as specific pages that have been visited 
- Create customer profiles and criteria to filter visitors that are more likely to be interested in buying
- Alert and notify salespeople when new opportunities are available
- Integrate with sales and marketing solutions such as CRM, sales effectiveness, and lead generation software (lead capture, lead scoring, and lead intelligence)
