Tech Blog SEO Optimization Practical Guide: 7 Strategies to Reach Page 1 in Search Results

“I started my tech blog 3 months ago, but I only get 5 visitors per day.”

This is a common pain point for many developer bloggers. Even great content is meaningless if search engines can’t find it.

I was completely clueless about SEO at first:

• First post: SEO score 47/100 (dismal)
• Search visibility: virtually none
• Traffic: only from direct link sharing

But with a systematic approach, I achieved:

• Second post: SEO score 80/100 (+33 points)
• Third post: SEO score 75/100 (consistently maintained)
• Core keyword density: 0.27% → 1.89% (7x improvement)

In this post, I’ll share 7 SEO optimization strategies tailored for tech blogs with real-world data.

📊 Tech Blog vs General Blog: SEO Differences

General Blog SEO

• Keywords: Broad (e.g., “restaurants”, “travel”)
• Competition: Extremely fierce
• Content Length: Short works (500-1,000 words)
• Updates: Timeliness matters

Tech Blog SEO

• Keywords: Specific (e.g., “TypeScript monorepo setup”)
• Competition: Relatively lower
• Content Length: Longer is better (2,000-5,000 words)
• Updates: Accuracy + currency

Key Difference: Tech blogs win with long-tail keywords + in-depth content

The Value of Page 1

Google search result click-through rate (CTR) data:

• 1st position: 27.6%
• 2-3rd positions: 15.8%
• 4-6th positions: 11.0%
• 7-10th positions: 6.1%
• Page 2 and beyond: 0.78%

Conclusion: Reaching page 1 is essential. Even 10th place is 8x better than page 2.

🎯 SEO Basics: Score Calculation Method

This is the evaluation criteria for my blog analyze-seo tool.

7 Evaluation Categories

Category	Points	Evaluation Criteria
Title Length	5	≤60 characters (mobile optimization)
Excerpt Length	5	150-160 characters (search preview)
Content Length	10	Minimum 1,500 words
Keyword Density	30	0.5-2.5% (most important)
Section Distribution	20	Keywords in ≥50% of sections
Title Keywords	15	Keywords in title
Excerpt Keywords	15	Keywords in excerpt

Total: 100 points
Goal: 70+ points (high probability of page 1 ranking)

Actual Score Changes

First Post (SEO ignored):

• Keyword density: 0/30 points (critical failure)
• Section distribution: 10/20 points
• Total: 47/100

Second Post (SEO optimized):

• Keyword density: 25/30 points ✅
• Section distribution: 20/20 points ✅
• Total: 80/100

Improvement Point: Reduced tags from 5 to 3 (keyword focus)

---

🔑 Strategy 1: Keyword Selection – Balancing Search Volume vs Competition

Wrong Keyword Selection

❌ Bad Example 1: Too Broad

tags:
  - "programming"  # Search volume: high, competition: fierce → impossible to rank
  - "development"
  - "coding"

❌ Bad Example 2: Too Specific

tags:
  - "TypeScript 5.3.2 pnpm workspace tsup esbuild configuration"  # Search volume: 0

Correct Keyword Selection

✅ Good Example: Long-tail Keywords

tags:
  - "Claude Code"  # Specific but has search demand
  - "developer"  # Clear target
  - "AI"  # Trending keyword

Result: SEO 80/100

3-Step Keyword Selection Process

Step 1: Brainstorming (10 candidates)

• List keywords related to post topic
• Example: “Claude Code”, “AI coding”, “dev productivity”, “pair programming”, “automation”

Step 2: Search Volume Research

• Google Trends: Check search trends
• Keyword Planner: Monthly search volume
• Competitor Analysis: Keywords of top-ranking blogs

Step 3: Final Selection (3-5 keywords)

• 1 Core Keyword: Most important keyword
• 2-4 Supporting Keywords: Related keywords

Important: Limit tags to 3-5 (too many dilutes density)

Real-World Case

Part 1 Post:

• Draft tags: “Claude Code”, “AI”, “dev productivity”, “automation”, “pair programming” (5 tags)
• SEO score: 47/100
• Problem: All keyword densities below 0.5%

After Optimization:

• Final tags: “Claude Code”, “developer”, “AI” (3 tags)
• SEO score: 80/100
• Improvement: “developer” appeared 25 times, “AI” 55 times (density 0.86%, 1.89%)

Key Learning: Reduce number of keywords, choose words that frequently appear in content

---

📈 Strategy 2: Keyword Density Optimization (0.5-2.5%)

What is Keyword Density?

Keyword Density = (Keyword Occurrences / Total Words) × 100

Goal: 0.5-2.5%

Example:

• Total words: 3,000
• “SEO” occurrences: 30
• Density: (30 / 3000) × 100 = 1.0% ✅

Density Evaluation

Density	Rating	Description
< 0.5%	❌ Too low	Insufficient keyword relevance
0.5-2.5%	✅ Optimal	SEO optimal range
> 2.5%	⚠️ Keyword stuffing	Risk of Google penalty

Before/After Comparison

Before (Part 2 Draft):

tags:
  - "Claude Code"  # 8 times, 0.27% ❌
  - "project"      # 7 times, 0.24% ❌
  - "automation"   # 8 times, 0.27% ❌

SEO score: 40/100

After (Changed tags):

tags:
  - "Claude Code"  # 8 times, 0.27% (unchanged)
  - "development"  # 25 times, 0.86% ✅
  - "AI"           # 55 times, 1.89% ✅

SEO score: 75/100 (+35 points!)

How to Increase Keyword Density

1. Natural Placement

❌ Bad Example (keyword stuffing):

SEO is important. To optimize SEO, you need SEO strategies.
If you ignore SEO, your SEO score will be low.

✅ Good Example (natural placement):

Search engine optimization (SEO) is essential for blog growth.
Systematically applying SEO strategies like keyword density and section distribution
significantly improves search visibility.

2. Include Keywords in Section Titles

## SEO Optimization Strategy 1: Keyword Selection
## Strategy 2: SEO Score Calculation Method
## Practical Tool: blog analyze-seo

3. Keywords in Code Comments

// Calculate SEO score
function calculateSeoScore(content: string): number {
  // Analyze keyword density
  const density = analyzeKeywordDensity(content);
  // ...
}

4. Keywords in Image Alt Text

📑 Strategy 3: Section Distribution Optimization (≥50%)

What is Section Distribution?

Definition: Percentage of sections (H2, H3) that contain keywords

Goal: ≥50%

Example:

• Total sections: 20
• Sections with keywords: 12
• Section distribution: 12/20 = 60% ✅

Before/After Comparison

Before (Part 2 Draft):

## 📋 Project Overview           ← No keywords
## Epic 1.0: Project Setup       ← No keywords
## Epic 2.0: WordPress API       ← No keywords
...

Section distribution: 6/28 = 21.4% ❌

After (Changed tags to “development”, “AI”):

## 🎯 Development Process Overview        ← Contains "development" ✅
## 🗓️ Day 3-13: Sequential Execution      ← Implies "development"
## 💡 Key Learning: Development in AI Era ← Contains "AI", "development" ✅
...

Section distribution: 15/28 = 53.6% ✅

Section Title Writing Tips

1. Natural Keyword Placement

❌ Bad Example:

## SEO SEO SEO Optimization Methods
## Blog Blog's SEO Strategies

✅ Good Example:

## SEO Optimization Practical Guide
## 7 Strategies to Boost Blog Search Visibility

2. Use Numbers (improves CTR)

## 7 SEO Strategies
## 3-Step Keyword Selection Method
## Boost SEO Score in 5 Minutes

3. Question Format (reflects search intent)

## Why Is My SEO Score Low?
## How to Increase Keyword Density?

📝 Strategy 4: Title Optimization (≤60 Characters)

Why Title Length Limit?

• Google Search Results: Displays up to 60 characters
• If Exceeded: “…” truncation (reduces CTR)

Title Structure

Formula: [Core Keyword] + [Specific Value] + [Number]

Example:

📚 Strategy 6: Content Length (Minimum 1,500 Words)

Correlation Between Content Length and SEO

Google Research Results:

• Page 1 average word count: 1,890 words
• #1 position average word count: 2,416 words

Reasons:

1. Longer content = More information = Higher user satisfaction ↑

1,000-1,500	7	Average
1,500-3,000	10	Optimal ✅
> 3,000	9	Very long (0.9x weight)

Optimal: 1,500-3,000 words (sufficient information without reading burden)

Real-World Cases

Part 1 Post:

• Word count: ~4,500 words

• Score: 9/10

Part 2 Post:

• Word count: ~2,900 words
• Weight: 1.0x
• Score: 10/10 ✅

How to Increase Length (Maintaining Quality)

## SEO Optimization Methods
### Keyword Selection
### Keyword Density
### Section Distribution

🏷️ Strategy 7: Metadata Optimization

Slug (URL)

Categories

Role: Content classification + internal linking

  - "Developer Productivity"

Tags

Role: Keyword definition + SEO

Rules:

• 3-5 or fewer
