How To Identify B2B Website Visitors for Sales Follow Up

98%+ of visitors to B2B websites don’t convert - they don’t fill out a form or identify themselves in any way. They land on your site, read some content, and leave anonymously.

That’s a massive amount of purchase intent you’re not capturing.

This post covers how to identify those anonymous visitors at both the account level and the person level, and how to incorporate that data into a sales follow-up workflow.

Two Trends Shaping Visitor ID Strategy

1. B2B buyers research online before ever talking to sales.

The percentage of the B2B research process that happens online before a buyer contacts a vendor is approaching 100%. Buyers read your blog, your case studies, your pricing page - and never raise their hand. If you’re not capturing signals from that research phase, you’re missing the window.

2. Visitor ID tools are evolving as privacy laws and cookie changes shift the landscape.

Third-party cookie deprecation and GDPR enforcement have changed what’s possible. The tools that work today look different than they did a few years ago. Staying current on what’s actually effective matters.

The Allbound Sales and Marketing Approach

The most effective framework for acting on visitor data is what’s sometimes called “allbound” - a blend of inbound marketing and outbound sales that respects the buyer’s research process while providing consultative guidance.

Also called “inbound-led outbound,” this positions sales reps as content concierges who proactively reach out to decision-makers who have already shown interest. Rather than cold outreach to strangers, you’re following up with companies or people who already know who you are.

Why Google Analytics Isn’t Enough

Standard analytics tells you how many people visited your site and what pages they viewed. It doesn’t tell you which companies those visitors are from, let alone which individuals.

Specialized “Visitor ID” or “IP to Company Resolution” tools fill that gap. These tools match IP addresses to company records, giving you a feed of companies that visited your site even if no one filled out a form.

A realistic expectation on match rates: most tools top out around 30%. ISP traffic and VPN usage mean a significant chunk of visits can’t be resolved to a company. But 30% of your website visitors is still a meaningful signal to work with.

Account-Level Visitor ID Tools

These tools identify which companies visited your site. They don’t tell you which specific person - just the organization.

Evaluation criteria to prioritize:

Lightweight implementation (a JavaScript tag or native integration - no heavy setup)
Freemium pricing or clear upfront costs
Built-in outreach automation or strong integrations with your CRM and sales tools

Tools worth evaluating:

Apollo.io - Recommended as the primary choice for early-stage startups. If you’re already using Apollo.io for outbound, the website visitor ID feature integrates directly into your existing workflow.
Dealfront (formerly Leadfeeder) - Well-established account-level identification tool with strong integrations
Leadlander - Around $89/month for up to 100 leads, straightforward pricing
Clearbit - Now owned by HubSpot; API access has become more restricted
Factors.ai - Includes custom account scoring features for prioritizing which visitors to act on

Person-Level Visitor ID Tools

Person-level tools go further - they attempt to identify the specific individual who visited your site, not just the company.

Important legal considerations:

This category of tools works in the United States but raises significant legal questions under GDPR for EU visitors. Before implementing, update your privacy policy and terms of service to reflect the data you’re collecting and how you’re using it.

On cookies: First-party cookies from direct website visits continue to function even as third-party tracking restrictions tighten. Tools that rely on first-party data are more durable as the landscape evolves.

Recommended outreach approach: When you do identify an individual visitor, LinkedIn connection requests are the most professional and respectful way to initiate contact. A cold follow-up that references exactly what someone read on your site can feel invasive - lean toward relationship-building rather than surveillance-style outreach.

Tools in this category:

RB2B - Freemium model that sends Slack notifications when individuals visit your site, including LinkedIn profile URLs, names, titles, and companies. Low barrier to get started.
Pearldiver.io - Around $387/month for 2,000 web visits, includes contact and account data with Zapier integrations for workflow automation

Putting It Together

The practical workflow:

Install an account-level visitor ID tool (Apollo.io if you’re already in that ecosystem, or Dealfront as a standalone)
Set up alerts or a daily review of which companies visited
Cross-reference against your existing CRM to see if these are known accounts or net new
For net new accounts with meaningful page views (pricing, case studies, solutions pages), add them to a targeted outreach sequence
If using person-level ID tools, route identified individuals to LinkedIn connection requests first before any email outreach

Visitor ID isn’t a silver bullet - match rates are imperfect and not every visitor is a buyer. But capturing the signal from even a fraction of your traffic gives your sales team a warm list to work with every week, built from people who already know your product exists.
