Why You Need to Measure Your Knowledge Base’s Effectiveness

Launching a knowledge base (KB) is just the start. You might be tracking views, search terms, and user ratings, but is your knowledge base really solving users’ problems?

Many companies collect data but don’t act on it. High page views look good on dashboards, but if users keep searching for answers without success, your KB isn’t doing its job.

From my experience as a Knowledge Manager, I’ve seen teams fall into the trap of tracking metrics without using the insights. Tracking is just step one. The real value is in understanding the data and using it to improve your content and support experience.

In this article, I’ll guide you through the most important knowledge base metrics and, more importantly, how to turn them into actions that make your KB work better for your users, your support team, and your business.

The Metrics That Matter for Your Knowledge Base

Not all metrics tell the full story. Some look impressive on dashboards but say little about whether your knowledge base is actually solving user problems. To truly assess performance and identify opportunities for improvement, you need to focus on metrics that reflect engagement, effectiveness, and content health.

Here are the key categories to pay attention to, and why they matter:

5 Categories of Knowledge Base Metrics

1. Usage & Engagement Metrics

These tell you how users interact with your content.

  • Top Viewed Articles
    Identify what your users are reading most. High views may indicate relevance or a problem area that users frequently face. 
  • Average Time on Page
    Time spent reading helps assess if users are actually engaging with content. Too little time may suggest they didn’t find it useful; too much time could mean the article is confusing or too long.
  • Bounce Rate
    A high bounce rate on an article might mean users aren’t finding what they need and are giving up or escalating to support.

Why it matters: High engagement can be good, but only if it leads to problem resolution. Combine these metrics with search and feedback data for context.

2. Search Analytics

Your search data is a goldmine for identifying gaps and improving findability.

  • Zero-Result Searches
    These are gold. They show you exactly where your content is missing. Analyze these regularly to identify new content opportunities or missed synonyms.
  • Search Success Rate
    This tells you how often users successfully find relevant content after performing a search. A low rate suggests either poor search configuration or mismatched terminology.
  • Exit searches
    Happen when users search and leave without clicking anything. This points to irrelevant or unhelpful results.
  • Top Search Queries
    Track what users are searching for most often. These terms should directly inform your article titles, headings, and metadata.

Why it matters: If users can’t find what they need, even the best-written content won’t help. Search analytics should directly inform your content roadmap.

3. Feedback & Quality Metrics

Direct user input adds valuable insight:

  • Article Ratings (thumbs up/down, stars, etc.)
    Simple but powerful. Track trends, not just individual ratings.When paired with views or search terms, these ratings help you prioritize updates.
  • User Comments on Articles
    Comments can offer context on what’s missing, confusing, or particularly helpful. Pay attention to patterns over time.

Why it matters: Feedback shows what users think, not just what they do.

4. Support Deflection & Ticket Metrics

These indicate if your knowledge base is reducing support workload:

  • Self-Service Score (or known as deflection rate)
    Measures the percentage of users who found answers without opening a ticket. This is a key KPI for most knowledge bases.
  • Contact Rate After Viewing an Article (CRAVA)
    Shows how often users still reach out to support after reading content. High CRAVA on certain articles suggests they aren’t delivering what users need.
  • Articles Linked in Tickets
    If support agents are frequently linking certain articles in tickets, it signals those pieces are valuable and could be promoted or improved for better self-service.

Why it matters: A well-performing knowledge base reduces repetitive tickets and empowers users. If your deflection rate is low, it’s time to reevaluate content quality or discoverability.

5. Content Maintenance & Improvement Metrics

A healthy knowledge base requires regular upkeep.

  • Outdated Articles / Articles Needing Review
    Track how many articles are flagged as outdated. A high number signals poor content hygiene, which can hurt user trust.
  • Orphaned Articles (No Links or Views)
    Articles that no one visits and no other content links to are often dead weight. These harm credibility and usability. Decide whether to update, merge, or retire them.
  • Article Age / Last Updated
    Articles that haven’t been updated in 6–12 months may be outdated. Stale content is a silent killer. A regular audit of old articles ensures accuracy and builds trust.

Why it matters: Even accurate content can lose trust if it looks neglected. Maintenance metrics help prioritize updates and audits.

6. Overall Knowledge Base Health Indicators

Knowledge Base Coverage
How well does your KB cover the top contact drivers or common customer issues? A simple mapping exercise between support tickets and article topics can expose gaps.

Content Gap Analysis Results
Use content gap analysis to pinpoint what’s missing. This should be done periodically, using search gaps and ticket trends to guide your roadmap.

Digging Deeper: What the Data Really Tells You

Metrics can give you a snapshot, but without context, they can also be misleading. It’s easy to assume that high numbers equal success, but sometimes, the story behind the data tells a different tale.

Let’s break down some common scenarios where numbers look good on the surface but hide opportunities (or problems) underneath.

1. High Views ≠ High Value

An article with thousands of views might seem like a win. But ask yourself:

  • Are users returning multiple times because the article is confusing or incomplete?
  • Is the title attracting clicks, but the content failing to deliver?
  • Are users submitting tickets right after viewing it?

Actionable Insight: Pair high view counts with time on page, exit rate, and support ticket tags. If users keep coming back, or escalate to support, that article needs a rewrite, not a celebration.

2. Zero-Result Searches Are Missed Opportunities

An increase in zero-result searches often indicates:

  • Users are using terms your content doesn’t include.
  • Important topics are not covered at all.
  • Search is too narrow or sensitive to phrasing.

Actionable Insight: Regularly review zero-result reports and align article keywords with how users naturally phrase their questions. Even a small update in terminology can make a big difference.

3. Positive Feedback? Double-Check It

Article ratings and thumbs-up feedback are helpful, but they’re not always reliable:

  • Low response rates can skew data.
  • Some users may click “Yes, this helped” just to move on.
  • Negative feedback is often more informative than positive.

Actionable Insight: Use comments and follow-up surveys (when possible) to gather more detailed input. Don’t over-rely on positive feedback as a quality stamp.

4. Outdated Articles That Still Perform

You may find old articles consistently getting traffic, but are they still accurate?

  • Legacy content can be based on outdated processes or tools.
  • Even minor changes (UI updates, policy changes) can cause confusion.
  • Support agents might still be linking to them out of habit.

Actionable Insight: Flag articles over 6–12 months old for review, especially those with high traffic or deflection value. Consider creating dashboards to track content age and prioritize audits.

The takeaway? Don’t stop at the dashboard. Ask why. Every data point is a conversation starter, an opportunity to get closer to what your users really need.

Turning Insights into Action

So you’ve gathered the right metrics and uncovered patterns in the data. Now what? Metrics only create value when they lead to strategic, informed improvements. This section shows how to take those insights and turn them into changes that actually improve the user experience, and reduce ticket volume.

Make Your Metrics Count

1. Optimize Content Based on Search Behavior

Your search analytics should directly influence your editorial calendar.

  • Add missing content for common search terms with zero results.
  • Update existing articles to include phrasing users actually use, not just internal terminology.
  • Restructure confusing articles that have high search-exit rates.

Example: If users consistently search for “reset login” and leave quickly, it may mean your “Password Reset” article isn’t showing up, or the title isn’t intuitive.

2. Improve Resolution Rates with Article Design

Even strong content can fail if it’s poorly presented.

  • Use clear headings and step-by-step formatting.
  • Add screenshots or GIFs to guide users visually.
  • Include confirmation language, like “You should now see…”

Pro tip: Articles that begin with context-setting (e.g., “Use this if you forgot your password, but can still access your email”) tend to reduce misdirected searches.

3. Fix or Retire Low-Performing Content

Some articles drag down your KB, cluttering search and confusing users.

  • Archive or merge stale, low-traffic articles.
  • Rewrite those with poor feedback or short time on page.
  • Reevaluate articles that consistently trigger follow-up tickets.

Tip: Create a recurring “content cleanup” process using metrics like age, views, deflection rate, and last update date.

4. Connect the KB with Real Support Cases

Your ticket system is a rich source of knowledge gaps.

  • Tag tickets with related article names (or lack thereof).
  • Identify topics where support teams are writing the same answers over and over.
  • Use saved replies and macros as inspiration for new or improved KB articles.

Collaboration idea: Run regular syncs with support agents to collect their “top 5 missing or outdated articles.”

5. Make Small Changes Often, Not Big Changes Rarely

You don’t need a massive overhaul to improve your knowledge base. In fact, small, frequent updates usually lead to better long-term results.

  • Set a monthly review of key metrics (top searches, zero-result queries, worst-rated content).
  • Build lightweight processes for submitting feedback and flagging issues.
  • Document your changes and track how they affect performance over time.

Mindset shift: Treat your KB like a product, always in iteration mode.

Tools and Dashboards That Help You Stay on Track

You don’t need to be a data analyst to make sense of your knowledge base metrics, but you do need the right tools and visibility. Whether you’re working in Zendesk, Freshdesk, Intercom, or another platform, setting up effective dashboards and workflows makes all the difference between scattered insights and a strategic content operation.

Here’s how to get started:

1. Use Your Help Center’s Built-In Analytics

Start with the basics. Most platforms provide default reports such as:

  • Top-viewed and most-rated articles
  • Common search terms and zero-result queries
  • Self-service score or deflection rate
  • Article feedback (thumbs up/down, comments)

Quick win: Automate weekly or monthly digests to keep track of top/bottom content without manually pulling data.

2. Bring in Google Analytics for Behavior Insights

Your help center is still a website, so why not treat it like one?

Google Analytics (GA4) helps you understand:

  • How users navigate through articles
  • Bounce rates and exit pages
  • Time spent on specific content
  • Click-throughs from the home page or search

Bonus: Set up custom events in GA to track interactions like “Was this helpful?” clicks or internal search usage.

3. Make Search Work Harder with Algolia or Elasticsearch

If your help center uses Algolia or Elasticsearch, you have powerful search logs at your fingertips:

  • Analyze top queries, filters, and click-through rates
  • Surface zero-result searches and reformulations
  • Improve ranking by tuning relevance rules or synonyms

Actionable tip: Use zero-result data from Algolia or Elasticsearch to inform new article creation or add missing keywords to existing content.

4. Build or Customize Dashboards in BI Tools

For cross-platform visibility or deeper analysis, consider tools like:

Example: Create a dashboard that flags articles with high views but poor feedback, or content older than 6 months with high search volume.

5. Track Content Health Internally

Not all important metrics come from user activity. Use a content audit spreadsheet or internal dashboard to track:

  • Last updated date
  • Responsible SME or owner
  • Ticket deflection rate (if available)
  • Planned reviews or rewrite status

Pro tip: Color-code articles based on urgency: green (fresh), yellow (due for review), red (needs attention ASAP).

6. Integrate with Support Workflows

Data isn’t just numbers, it’s what your support team hears every day.

  • Tag tickets with article IDs or topics
  • Collect article feedback directly from agents (via Slack, forms, or macros)
  • Track macro-to-article success rates using linked analytics

Real-world win: Create a “feedback loop” dashboard showing articles most often linked from tickets, and how often those tickets are reopened.

7. Make Metrics Visible Across Teams

Transparency builds momentum.

  • Share monthly insights with support, product, and customer success
  • Include visual highlights: top 5 improved articles, search term trends, or ticket deflection gains
  • Use insights to align with product updates, seasonal issues, or onboarding flows

Culture tip: When other teams see the impact of a well-maintained KB, they’re more likely to contribute and collaborate.

Bottom line: metrics matter, but only if they’re easy to access and tied to decisions. Whether you’re running basic reports or digging deep into search behavior with Elasticsearch or GA4, choose tools that work for your stage, and grow with you over time. 

Maintaining a Feedback Loop

Creating a useful knowledge base isn’t a one-and-done project, it’s a continuous cycle of listening, analyzing, updating, and improving. To keep your content relevant and helpful, you need more than metrics: you need a systematic feedback loop.

Here’s how to build one that actually works:

Scheduling Regular KB Audits

Even the best articles go stale. Products change. Policies evolve. User behavior shifts. That’s why recurring audits are non-negotiable.

  • Quarterly or biannual reviews are a good starting point.
  • Focus on high-impact articles (most viewed, most linked in tickets, or critical workflows).
  • Use audit spreadsheets or dashboards to track review status, last update, and assigned owners.

Pro tip: Don’t wait for someone to complain. Schedule audits like you would maintenance on critical systems, because that’s what they are.

Setting Goals and Benchmarks

You can’t improve what you don’t measure. Set clear, realistic benchmarks for your content performance:

  • Thumbs-up rate above 75%
  • Zero-result searches reduced by 30% in 6 months
  • Support deflection rate improved by X% over a quarter
  • 90% of content reviewed at least once every 6 months

These goals will help you track progress and rally support from stakeholders who care about ROI.

Quick win: Share these goals with leadership to show that the knowledge base isn’t just a content repository, it’s a strategic tool.

Making Iteration a Habit, Not a Project

One-off overhauls can burn out your team and create long stretches of neglect. Instead, build ongoing improvement into daily workflows.

  • Review feedback and zero-result data weekly.
  • Host a monthly KB check-in with support reps to surface real issues.
  • Assign “content champions” across departments to own key areas.
  • Add small improvements to your backlog or sprint planning, just like you would for product features.

Sustainable strategy: Think of your KB as a living product. Continuous iteration keeps it alive and aligned with your users’ real needs.

By embedding these practices into your routines, you ensure your knowledge base grows with your business, and always reflects what your users actually need.

Final Thoughts: A Great KB is Never Finished

A knowledge base isn’t just a library, it’s a living, breathing extension of your support strategy. And like any living system, it needs regular care, informed decisions, and a steady feedback loop to thrive.

From Passive Tracking to Proactive Management

It’s easy to fall into the trap of just reporting. You track views, thumbs up, and search terms, but what happens next?

Real impact happens when you shift from tracking to managing:

  • Use search analytics to spot content gaps.
  • Treat article feedback as a roadmap, not a scoreboard.
  • Turn zero-result queries into your next content sprint.
  • Align KB updates with product changes, support trends, and customer behavior.

The goal isn’t just “more content.” It’s better content, used more often, that solves real problems.

Final Tips for a Smarter, Data-Driven Knowledge Base

Here’s a quick checklist to guide your next steps:

Audit regularly — schedule reviews, not reactions
Build dashboards — make insights visible and actionable
Listen to search — zero-result queries are gold mines
Close the loop — involve support in flagging and fixing content gaps
Set goals — and share progress with your team
Start small, iterate often — improvement is a habit, not a one-time project

A successful knowledge base isn’t about perfection, it’s about responsiveness. If your KB is evolving alongside your customers’ needs, you’re doing it right.

And if you’re using data to guide that evolution?

Then you’re not just maintaining a knowledge base, you’re managing a knowledge asset.
