By: Robert Soares | You can track a lot of things. Open rates. Time on page. Scroll depth. Device type. Location. Return visits. Forwarded views.
But more data isn't always better data. Some metrics tell you exactly what you need to know. Others look impressive and mean nothing.
Here's what actually matters when measuring document engagement.
The Core Metrics That Drive Decisions
Let's start with the numbers that change how you work.
1. Opens (View Rate)
What it is: How many people opened your document divided by how many received it.
Why it matters: If nobody opens, nothing else matters. This is your baseline.
What it tells you:
- Is your subject line working?
- Is your delivery method effective?
- Is the recipient interested at all?
Benchmark: Aim for 60%+ open rates on direct sends. Mass distributions will be lower. For context, B2B email benchmarks from beehiiv show average open rates around 32%, so document open rates on targeted sends should significantly exceed that.
When it's misleading: Opens don't mean reads. Someone who opens for 2 seconds counts the same as someone who reads for 10 minutes. That's why you need the next metric.
2. Time Spent (Engagement Duration)
What it is: How long someone actually viewed your document.
Why it matters: This separates actual readers from quick glances.
What it tells you:
- Did they engage with the content?
- How carefully did they review it?
- Is your document the right length?
Benchmark: Time should roughly match what you'd expect for thorough reading. A 10-page document with images might need 5-7 minutes. If average time is 45 seconds, people aren't reading.
How to calculate: Total viewing time divided by total pages gives you average time per page. Under 30 seconds per page usually means skimming. Over 60 seconds per page means careful reading.
3. Completion Rate (Scroll Depth)
What it is: The percentage of viewers who reached the end of your document.
Why it matters: Starting is easy. Finishing means your content held attention.
What it tells you:
- Is your document too long?
- Is there a specific point where people bail?
- Does your content maintain interest?
Benchmark: 40-60% completion is solid for longer documents. 70%+ is excellent. Under 20% means something's wrong.
The insight: Completion rate often matters more than open rate. 50 people who read everything are worth more than 200 people who glanced at page one. Research from Content Marketing Institute and MarketingProfs shows that 73% of B2B marketers use conversions as their top content metric, but completion rate is the leading indicator that predicts those conversions.
4. Page-Level Engagement
What it is: Which specific pages got viewed and for how long.
Why it matters: This is where it gets interesting. You see exactly where attention lands.
What it tells you:
- Which sections resonate?
- Which sections get skipped?
- What's actually driving interest?
Example: Your proposal has 12 pages. Data shows:
- Pages 1-2: 90% viewed (intro, most people start here)
- Pages 3-5: 45% viewed (methodology, many skip)
- Pages 6-8: 75% viewed (case studies, good engagement)
- Pages 9-10: 85% viewed (pricing, high interest)
- Pages 11-12: 30% viewed (team bios, most skip)
Now you know: Pricing and case studies matter most. Methodology and bios could be shorter or moved.
5. Return Visits
What it is: How many times someone comes back to view the same document.
Why it matters: Return visits signal active consideration.
What it tells you:
- Are they comparing you to competitors?
- Are they showing it to colleagues?
- Is a decision being made?
Benchmark: 2+ visits often indicates serious interest. 5+ visits might mean they're in final consideration or sharing internally.
The insight: A prospect who opens your proposal three times over a week is more engaged than someone who opened once for the same total time. Gartner research on the B2B buying journey shows that typical buying groups include 6 to 10 decision makers. Multiple views may indicate your document is being shared with stakeholders.
Secondary Metrics Worth Watching
These matter, but they support the core metrics rather than drive decisions alone.
Device Type
What it is: Desktop vs. mobile vs. tablet.
Why it matters: Context affects engagement. Mobile readers might be distracted or time-pressed. Desktop readers might be working.
What to do with it: If 60%+ of your views are mobile, make sure your documents are mobile-friendly. Large tables and tiny text don't work on phones.
Location
What it is: Geographic location based on IP address.
Why it matters: Can reveal unexpected patterns.
Example use cases:
- Prospect in New York views from London. Maybe they forwarded it.
- Training document gets views from an office you didn't know existed.
- Proposal views cluster in a city where your competitor is headquartered. Could be competitive research.
Caveat: VPNs and remote workers make this less reliable than it used to be.
Time of Day
What it is: When people view your documents.
Why it matters: Viewing patterns tell you about context.
What it tells you:
- 9 AM Monday: They're working through priorities
- 10 PM Thursday: Personal research or overtime
- Weekend views: Either very interested or catching up on backlog
What to do with it: If most views happen in early mornings, schedule your follow-ups for that window.
Unique Viewers vs. Total Views
What it is: One person viewing three times = 1 unique viewer, 3 total views.
Why it matters: Helps you understand reach vs. depth.
Example:
- 100 total views from 20 unique viewers = high engagement, smaller reach
- 100 total views from 90 unique viewers = broad reach, low repeat engagement
Both can be good depending on your goal.
Metrics That Look Important But Usually Aren't
Not everything that can be measured should be measured.
Downloads
The trap: High downloads feel like success.
The reality: Downloads mean they saved a copy. That's it. They might never open it. They might be archiving it for later (and never getting to later).
When it matters: If you're gating content, download count tells you lead volume. But it says nothing about engagement.
Shares
The trap: Shares feel viral.
The reality: One share that leads to a purchase is worth more than 100 shares that go nowhere.
When it matters: If you can track what happens after the share, great. If not, it's vanity.
Bounce Rate
The trap: Borrowed from website metrics, sounds important.
The reality: For documents, it's unclear what "bounce" even means. Someone who reads page one and leaves might have gotten what they needed.
Better alternative: Time on first page. If they spend 10 seconds and leave, that's a bounce. If they spend 2 minutes on page one, they engaged, even if they didn't continue.
Building a Metrics Dashboard That Works
Don't track everything. Track what changes behavior.
For Sales Documents
Primary metrics:
- Open rate by prospect
- Time spent
- Page-level engagement (especially pricing)
- Return visits
What to do with it:
- Prioritize follow-ups by engagement level
- Tailor conversations to what they focused on
- Time outreach to fresh views
HubSpot research shows that 54% of salespeople say selling got harder in 2024, yet those who use data to focus on engaged prospects still exceed their targets at higher rates.
For Marketing Content
Primary metrics:
- View-to-completion ratio
- Drop-off points (which page loses people?)
- Time spent on key sections
What to do with it:
- Improve or cut sections with high drop-off
- Double down on topics with high engagement
- Shorten or restructure underperforming content
For Training Materials
Primary metrics:
- Completion rate by employee
- Time spent (minimum threshold for meaningful engagement)
- Who hasn't started yet
What to do with it:
- Send targeted reminders to non-completers
- Identify sections that need clarification
- Prove compliance with timestamps
Turning Metrics Into Action
Data is useless if you don't act on it. Here's a simple framework.
Weekly Review (15 minutes)
Look at:
- Which documents got the most engagement this week?
- Who are your hottest prospects based on viewing patterns?
- Any unexpected drop-off points in key content?
Act on:
- Schedule follow-ups with high-engagement viewers
- Note content that needs improvement
Monthly Analysis (30 minutes)
Look at:
- Trends in completion rates
- Average engagement times
- Best and worst performing documents
Act on:
- Update or retire underperforming content
- Replicate patterns from top performers
- Adjust document length or structure
Quarterly Strategy (1 hour)
Look at:
- Overall engagement trends
- Correlation between engagement and outcomes (closes, conversions, compliance)
- Gaps in what you're tracking
Act on:
- Set new benchmarks
- Experiment with formats
- Improve tracking setup
Getting Started With Measurement
You don't need sophisticated analytics from day one. Start simple.
Minimum viable tracking:
- Did they open it?
- How long did they spend?
- Did they reach the end?
These three numbers tell you more than most marketers know about their content.
Next level: 4. Which pages got attention? 5. Did they come back?
Advanced: 6. Who specifically viewed? 7. What device and location? 8. What happened after they viewed (conversion tracking)?
Start at minimum viable. Graduate up as you learn what questions you need answered.
The Metrics That Matter Most
If you remember nothing else:
- Opens tell you if your delivery works
- Time spent tells you if your content engages
- Completion rate tells you if you held attention
- Page-level data tells you what resonates
- Return visits tell you who's seriously considering
Everything else is supporting information.
Track these five things, and you'll know more about your document engagement than 90% of people who send PDFs.
