Reading the Buyer Research Your Analytics Can't See
Your website analytics show you the buyers who filled out a form. They don't show you the ones who read three of your blog posts, asked about you in a private Slack community, and compared you to a competitor on a review site, all without ever leaving a trace you can attribute.
That invisible research is often called the dark funnel, and the honest answer to "how do we track it" is that you mostly can't, directly. What you can do is build a process that assumes it's happening and adjusts for it.

Why This Research Is Invisible by Design
A lot of pre-outreach research happens in places that don't report back to you at all: private communities, peer Slack groups, incognito browsing, word of mouth in a founder group chat. None of that shows up in a UTM parameter or a marketing attribution report, no matter how good your tracking setup is.
This isn't a tooling gap you can close with a better analytics platform. It's a structural feature of how people actually research vendors now, often deliberately avoiding a form fill for as long as possible to stay out of a sales pipeline before they're ready.
Indirect Signals Worth Watching Instead
- A spike in direct traffic to your site with no matching campaign, which often means word of mouth or a private share
- Search demand for your brand name or category terms rising in a way your own campaigns don't explain
- An inbound lead who already knows specific details about your product before the first call, a sign they've done real research somewhere you can't see
- A sudden inbound request from a company where nobody on your team has any recorded prior touch
None of these prove exactly what happened before the lead reached you, but taken together they're a reasonable substitute for the attribution data you're never going to get directly.
Treating the Sales Conversation as a Research Tool
Since you can't track the research directly, ask about it. A simple, direct question early in a first call, "what made you reach out now, and what have you already looked at," often surfaces more about the dark funnel than any tool could.
Log those answers somewhere your team can actually see patterns over time, not just in a rep's private notes. If several buyers mention the same review site or community independently, that's worth knowing about even without a dashboard proving it.
For example, a team reviews its last fifteen inbound demo requests and adds one field to the CRM: the first place the buyer says they heard about the company. After a month, several answers point to the same private community and one review site, neither of which appeared in web analytics. The team can then act on that pattern by showing up in that community, updating its profile on the review site, and adding a line about both to the first-call script. The mistake to avoid is asking the question once and never tallying the answers. A free-text field nobody reads is no better than having no data, so assign someone to review the answers monthly.
Where Semrush Fits Into This Picture
Semrush can't see private research, but it can show you search demand and content gaps around your category, which is a reasonable proxy for how much unattributed research interest exists even when you can't trace individual buyers.
If category search volume is rising and your form-fill volume isn't keeping pace, that gap is a rough estimate of how much research is happening without ever reaching your analytics, which is a more honest way to think about the dark funnel than assuming it doesn't exist just because you can't measure it directly.
Building for the Buyer You Can't See Yet
If a meaningful share of your buyers arrive already informed, your website and content need to hold up to someone who's already compared you to competitors, not just someone hearing about you for the first time. That's a content and positioning decision, not a tracking one.
MeetMyCRO's AI CRO, Roger, can help you think through what an already-informed buyer expects to see on a first call, if you want a second opinion on whether your current process assumes too little research has happened before that call.
A short, honest audit is a reasonable place to start: pull your last ten closed-won deals and ask each rep how much the buyer already seemed to know at the first meeting. A pattern of well-informed buyers is a strong hint that your visible funnel is only showing part of the real story.
What Good Looks Like
A sound approach to dark funnel research tracks indirect signals like search demand and unattributed direct traffic, asks buyers directly about their research process, and treats content as needing to satisfy an already-informed reader, not just a first-time visitor.

Frequently Asked Questions
Can we actually measure dark funnel activity directly?
Not with any real precision. The research happens in places, private communities, incognito browsing, word of mouth, that don't report back to standard analytics. The honest approach is to look for indirect signals rather than expecting a tool to solve the visibility problem entirely.
Is asking buyers directly about their research process actually useful?
Yes, more than most teams realize. A direct question on a first call about what they've already looked at often surfaces more real information than any indirect signal, and it costs nothing beyond remembering to ask and log the answer.
Should we build content assuming buyers already know a lot about us?
It's a reasonable assumption for at least some share of your inbound. If your content and site only address someone hearing about you for the first time, you may be underserving the buyers who've already done real research and are further along than a typical funnel stage would suggest.
