Reading Data: From Numbers to Insights
Article Three of Three in the Workshop: Economics of Content Creation
By now, we’ve built a solid subscription system. We’ve added a second income layer through affiliate marketing. But without data, all of this remains a shot in the dark.
Imagine running a physical store but not knowing which products sell most. You don’t know when customers come. You don’t know where they stand in the store. You’re operating blind. This is the reality of bloggers who don’t monitor their site data.
Data isn’t dry numbers. Data is facts about your reader. Where do they come from? What do they read? Where do they stop? Will they buy? Data answers all these questions.
Let’s learn how to become a data analyst for your site.
Google Analytics 4: The Foundation
If you haven’t heard of Google Analytics, it’s Google’s free tool for tracking visitors. And if you’re using it, you’re likely on the old version (Universal Analytics).
In 2024, Google migrated to Google Analytics 4 (GA4). It’s more powerful and intelligent than the previous version.

The Basic Difference:
Universal Analytics (Old): Based on “sessions.” It tells you: “100 people visited your site, and 50 of them read two pages.” But it doesn’t tell you what comes next.
GA4 (New): Tracks “events.” It tells you: “Person A entered from Google, read an article about Stripe, then clicked an affiliate link for Stripe, then went to Stripe’s site.” It tracks the complete journey.
How to Set Up:
- Go to analytics.google.com with your Google account
- Click “Create Account”
- Enter your site name and target countries
- GA4 gives you a tracking code. Copy it.
- In WordPress, install “MonsterInsights” or “Google Site Kit” plugin and paste the code
- Wait 24 hours, and data will start appearing
For the first two days of GA4, don’t worry if numbers look odd. Data needs time to stabilize. After a week, it becomes clear.
The User Journey: From Entry to Purchase
Now we have data. But which data do we focus on?
GA4 gives you hundreds of numbers. What matters is understanding the user journey (User Journey).
Think of it like this:
Stage One: Discovery
A reader searches for something on Google. Sees your article in results. Clicks it. This is the beginning. GA4 tracks:
- Where did they come from? (Google, Facebook, directly?)
- What search term did they use?
- What device are they on? (Phone, laptop?)
- Which country?
Stage Two: Exploration
The reader is now on your article. Now:
- How long did they stay?
- How much of the article did they read? (100% or stopped halfway?)
- Did they click any links?
- Did they read another article afterward?
Stage Three: Action
This is the most important part:
- Did they sign up for your newsletter?
- Did they subscribe to your paid service?
- Did they click an affiliate link?
- Did they leave a comment?
- Did they share the article?
Each of these actions needs to be an “event” in GA4.
Setting Up Events: Track What Matters
GA4 tracks visitors automatically. But to track things important to your business, you need to set up custom “events.”
Examples of Important Events:
- When someone starts a paid subscription: Event “subscription_started”
- When someone clicks an affiliate link: Event “affiliate_link_clicked”
- When someone downloads a PDF: Event “pdf_downloaded”
- When someone subscribes to your newsletter: Event “email_signup”
- When someone leaves a comment: Event “comment_posted”
How to Set Up an Event:
The easiest way is using a plugin like MonsterInsights. No coding needed.
- In MonsterInsights, go to “Events”
- Click “Add Event”
- Choose the event type (e.g., “Button Click”)
- Select the button you want to track (e.g., your “Subscribe Now” button)
- Name the event (e.g., “subscription_button_click”)
- Save. From now on, every click on that button is logged in GA4
After setting up events, GA4 transforms from a visitor counter into a tool that understands your reader’s behavior.
Heatmaps: Where Do Readers Stop?
GA4 tells you what a reader did. But it doesn’t tell you where they stopped reading.
For this, we need another tool: Hotjar.
Hotjar gives you a heatmap. It’s a screenshot of your page with colors:
- Red: Many visitors clicked there
- Yellow: Average clicks
- Blue: Few clicks
- Gray: Nobody clicked there
For example, you might discover:
- Your “Subscribe Now” button at the top gets almost no clicks (blue)
- But people scroll past it without reading (they’re moving down)
- The button at the bottom gets more clicks (red)
This means the button position is wrong. Moving it down might increase signups.
Scroll Heatmap:
Hotjar has another type: the Scroll heatmap. It shows you how many visitors reached the end of your article.
For example:
- 100% of visitors entered the page
- 80% read to 25% of the article
- 40% read to 50%
- 10% read to the end
If only 10% reach the end, there’s a problem. Is the article too long? Boring? Hard to read?
If most readers stop halfway, think: Is there a long, frustrating sentence? Is the language complicated? Focus on your first 50%—if it’s boring, nobody reads the rest.
Cost:
Hotjar is free for 35 sessions per month. If you’re starting out, that’s enough. Paid plans start at $39/month.

A/B Testing: Is This Better Than That?
Now we reach the smartest use of data: A/B testing.
The idea is simple: instead of guessing “which headline is better?” or “which image attracts more?”, you test both simultaneously and see which wins.
Example: You have an article about “best writing tools.” You want to improve clicks on your “Subscribe Now” button.
You choose two options:
- Version A (Original): Button with text “Subscribe Now” and red background
- Version B: Button with text “Try Free” and green background
You split visitors: 50% see Version A, 50% see Version B. After a week, you compare:
- Version A: 5% of visitors clicked the button
- Version B: 8% of visitors clicked the button
Version B wins! Now use it everywhere.
What Can You Test?
- Headlines: “Top 10 Tools” vs. “The Secret Tool That Changed My Life”
- Images: Personal photo vs. product image
- Button Position: Button at top vs. button at bottom
- Button Text: “Subscribe Now” vs. “Join Members”
- Colors: Red vs. blue vs. green
- Article Length: 2,000 words vs. 4,000 words
Tools:
Optimizely and Unbounce specialize in A/B testing. But they’re expensive.
Free alternative: use a WordPress plugin like WordPress AB Split Test.
One correct test can boost your earnings by 20-30%. Repeated tests, cumulatively, can double your income.
Building a Conversion Funnel
Every visitor travels a path. Some reach the end (purchase), others stop along the way.
A simple model:
- Visits: 10,000 visitors/month enter your site
- Reading: 5,000 of them read a complete article (50%)
- Interest: 1,000 click an affiliate link or subscribe button (20% of readers)
- Purchase: 100 actually buy (10% of interested)
This is the funnel. Each stage loses some people.
The question: where can we improve?
- If only 50% read completely: Articles are too long or boring. Test shortening and improving writing.
- If only 20% click links: Links aren’t clear or relevant. Place them better or make them more appealing.
- If only 10% purchase: Prices might be high or explanation insufficient. Test lower pricing or write more convincingly.
Every 1% improvement at each stage leads to significant growth at the end.
Which of Your Articles Perform Best?
One of the most important reports in GA4 is: which pages get most visitors?
Go to GA4 → Reports → Engagement → Pages and screens
You’ll see your pages ranked by visitors. But attention: high traffic doesn’t mean high profit.
Look at Other Columns:
- Average Engagement Time: How long did visitors stay? (Sign they enjoyed it)
- Bounce Rate: How many entered and left immediately? (Bad sign if high)
- Conversions: How many bought or subscribed? (Most important)
Example: Article A has 5,000 visitors/month but 80% bounce rate. Article B has 1,000 visitors but 20% bounce rate and 5% conversion.
Article B is far better! Quality beats quantity.
Focus effort on quality-bringing articles, not high-traffic ones. One good article generating 100 affiliate clicks beats 10 articles generating 5 clicks each.
Additional Analytics Tools
- Google Search Console: See search terms bringing visitors. Which keywords need work?
- Semrush: Analyze competitors. What are they doing better? (Paid, but powerful)
- Similarweb: Overall view of your site performance vs. competitors
- GTmetrix: Site speed. Slow speed = fewer visitors
Making Decisions: From Numbers to Actions
All this data means nothing if you don’t act on it.
Decision Framework:
- Observe: What does the data say?
- Understand: Why is this happening?
- Test: Does this solution work?
- Apply: If it works, use it everywhere
- Repeat: Find the next problem
Practical Example:
GA4 says: “50% of visitors come from mobile, but mobile conversion rate is 2% while desktop is 5%.”
Observation: Mobile performance is poor.
Understanding: Design might not be responsive. Buttons might be too small.
Testing: Improve mobile design. Test for a week.
Application: If conversion rises to 3-4%, adopt the new design.
Repeating: Now find the next problem.
A Tracking Sheet: Stay in Control
With all this data, it’s easy to feel overwhelmed. Simple solution: create a tracking sheet.
Example Sheet:
| Metric | Last Month | This Month | Goal | Notes |
|---|---|---|---|---|
| Total Visitors | 5,000 | 6,200 | 8,000 | Good growth |
| Click-Through Rate (CTR) | 3% | 4.2% | 6% | Link improvements helped |
| Conversion Rate | 2.1% | 2.8% | 4% | New A/B test underway |
| New Subscriptions | 15 | 22 | 30 | On track |
| Affiliate Income | $245 | $380 | $500 | 55% growth |
Every month, copy numbers from GA4 and paste here. Seeing trends is what matters. Small monthly improvements lead to major annual growth.

Summary: Thinking Like a Data Analyst
The difference between a blogger relying on intuition and one relying on data is the difference between a random driver and an engineer.
The random blogger writes what they love and hopes people love it. May succeed, may not.
The data-driven blogger says: “I’ll observe, test, learn.” Every month, the site improves. Earnings grow. Audience expands.
Data doesn’t lie. Numbers are honest. While opinions are fuzzy, data is clear. Choose clarity.

Closing: The Complete Circle
We’ve completed the three-part workshop:
Part One: We built a subscription system—the foundation of steady income.
Part Two: We added affiliate marketing—a second income layer.
Part Three: We learned to read data—to ensure everything runs efficiently.
Now you’re ready to build a real business from your site. Not a random blog, but a small company generating recurring income.
The next step depends on you. Will you start implementing? Or is this just information you’re reading?
Remember: The difference between successful and unsuccessful isn’t knowledge. Everyone has information. The difference is execution. Start today. Test. Learn. Repeat.
