Editor: Hendra WIjaya
Update: 15 December 2025
Baca: 13 menit

Technical SEO adalah fondasi yang menentukan apakah Google bisa crawl, index, dan rank website Anda dengan optimal. Konten berkualitas tidak akan ranking jika technical SEO berantakan. Artikel ini membahas semua aspek technical SEO—dari crawlability, site architecture, hingga Core Web Vitals—dengan actionable checklist untuk audit dan optimasi.

Apa Itu Technical SEO?

Technical SEO adalah praktik optimasi aspek teknis website agar search engine bisa crawl, index, dan understand konten dengan efisien. Berbeda dengan on-page SEO yang fokus pada konten, technical SEO fokus pada infrastruktur website.

Mengapa Technical SEO Critical?

Analogi Sederhana:

  • On-Page SEO = Interior rumah (furniture, dekorasi)
  • Technical SEO = Fondasi & struktur rumah (pondasi, atap, listrik)

Tanpa fondasi yang kuat, interior sebagus apapun tidak akan bertahan.

Studi Kasus: E-commerce Fix Technical Issues, Revenue Naik 240%

Sebuah toko online dengan 5000+ produk mengalami stagnasi traffic meski konten bagus:

Technical Issues yang Ditemukan:

  • 40% halaman tidak ter-index (blocked by robots.txt)
  • Duplicate content masif (product variations)
  • Site speed sangat lambat (8+ detik)
  • Mobile usability issues
  • Broken internal links 500+
  • No XML sitemap
  • Mixed content (HTTP + HTTPS)

Fixes yang Dilakukan (3 Bulan):

  1. Month 1: Fix crawl errors, robots.txt, sitemap, HTTPS
  2. Month 2: Resolve duplicate content, canonical tags, 301 redirects
  3. Month 3: Speed optimization, mobile fixes, structured data

Results Setelah 6 Bulan:

  • Indexed pages: 2,000 → 4,500 (125% increase)
  • Organic traffic: +185%
  • Page speed score: 28 → 87
  • Mobile usability errors: 45 → 0
  • Average position: 25 → 12
  • Organic revenue: +240%
  • Bounce rate: 68% → 42%

Investment: $3,000 (developer time)
ROI: 3,200% dalam 6 bulan

Crawling & Indexing

1. Robots.txt Optimization

Robots.txt memberi instruksi ke search engine bot tentang halaman mana yang boleh/tidak boleh di-crawl.

Best Practices

Good robots.txt Example:

# Allow all bots
User-agent: *
Allow: /

# Block admin & private areas
Disallow: /admin/
Disallow: /cart/
Disallow: /checkout/
Disallow: /my-account/
Disallow: /wp-admin/
Disallow: /wp-includes/

# Block search & filter pages (duplicate content)
Disallow: /*?s=
Disallow: /*?sort=
Disallow: /*?filter=

# Block unnecessary file types
Disallow: /*.pdf$
Disallow: /*.doc$

# Allow CSS & JS (important for rendering)
Allow: /wp-content/uploads/
Allow: /*.css$
Allow: /*.js$

# Sitemap location
Sitemap: https://example.com/sitemap.xml
Sitemap: https://example.com/sitemap-news.xml

Common Mistakes

❌ Blocking Important Pages:

Disallow: /blog/  # Blocks entire blog - BAD!

❌ Blocking CSS/JS:

Disallow: /*.css$  # Google can't render page properly
Disallow: /*.js$

❌ No Sitemap Reference:

# Missing sitemap = harder for Google to discover URLs

Tools untuk Test

  • Google Search Console → Robots.txt Tester
  • Screaming Frog → Configuration → Robots.txt

2. XML Sitemap

XML Sitemap adalah roadmap yang membantu search engine discover dan crawl halaman penting.

Sitemap Best Practices

Types of Sitemaps:

a) Main Sitemap (Index):

<?xml version="1.0" encoding="UTF-8"?>
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <sitemap>
    <loc>https://example.com/post-sitemap.xml</loc>
    <lastmod>2025-12-15</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://example.com/page-sitemap.xml</loc>
    <lastmod>2025-12-15</lastmod>
  </sitemap>
  <sitemap>
    <loc>https://example.com/product-sitemap.xml</loc>
    <lastmod>2025-12-15</lastmod>
  </sitemap>
</sitemapindex>

b) Post Sitemap:

<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url>
    <loc>https://example.com/article-slug/</loc>
    <lastmod>2025-12-15</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.8</priority>
  </url>
  <url>
    <loc>https://example.com/another-article/</loc>
    <lastmod>2025-12-10</lastmod>
    <changefreq>monthly</changefreq>
    <priority>0.7</priority>
  </url>
</urlset>

Sitemap Rules

  • ✅ Include: Important pages yang ingin di-index
  • ✅ Update: Automatic update saat ada konten baru
  • ✅ Size limit: Max 50MB atau 50,000 URLs per sitemap
  • ✅ Submit: Upload ke Google Search Console & Bing Webmaster
  • ❌ Exclude: 404 pages, redirected URLs, noindex pages, duplicate content

Dynamic Sitemap Generation

WordPress:

  • Yoast SEO (automatic)
  • Rank Math (automatic)
  • XML Sitemap Generator Plugin

Custom/Framework:

  • Auto-generate via script
  • Update on publish/update
  • Include lastmod timestamp

3. Crawl Budget Optimization

Crawl budget = jumlah halaman yang Google crawl di website Anda dalam periode tertentu.

Factors yang Mempengaruhi

  1. Site Authority: High DA = more crawl budget
  2. Site Speed: Faster site = more pages crawled
  3. Site Size: Larger sites need more budget
  4. Update Frequency: Frequently updated = more crawls
  5. Errors: Many errors = wasted budget

Maximize Crawl Budget

a) Remove Low-Value Pages:

  • Thin content pages
  • Duplicate pages
  • Expired/outdated content
  • Pagination overload

b) Fix Crawl Errors:

  • 404 errors
  • Broken links
  • Redirect chains
  • Server errors (5xx)

c) Optimize Internal Linking:

  • Important pages should be 3 clicks from homepage
  • Remove orphan pages (no internal links)

d) Use Crawl-Delay (If Needed):

# In robots.txt (only if server overload)
User-agent: *
Crawl-delay: 10

⚠️ Warning: Only use if server can’t handle crawl rate—slows indexing.

4. Canonical Tags

Canonical tags tell Google which version of duplicate/similar pages is the original.

When to Use

Scenario 1: Product Variations

example.com/tshirt?color=red
example.com/tshirt?color=blue
example.com/tshirt?color=green

→ All should canonical to:
example.com/tshirt

Scenario 2: Pagination

example.com/blog/page/1/
example.com/blog/page/2/

→ Use rel="next" and rel="prev" OR
→ Self-referencing canonical

Scenario 3: HTTP vs HTTPS

http://example.com/page/
https://example.com/page/

→ HTTP version canonicals to HTTPS

Implementation

<link rel="canonical" href="https://example.com/original-page/" />

Best Practices

  • ✅ Use absolute URLs, not relative
  • ✅ Canonical should be indexable (not noindex)
  • ✅ Canonical URL should return 200 status
  • ✅ Self-referencing canonical on originals
  • ❌ Don’t chain canonicals (A→B→C)
  • ❌ Don’t canonical to different content

5. Noindex, Nofollow Tags

Control what Google indexes dan follows.

Meta Robots Tag

<!-- Don't index this page, but follow links -->
<meta name="robots" content="noindex, follow" />

<!-- Don't index, don't follow links -->
<meta name="robots" content="noindex, nofollow" />

<!-- Index page, don't follow links -->
<meta name="robots" content="index, nofollow" />

When to Use Noindex

  • ✅ Thank you pages
  • ✅ Admin/login pages
  • ✅ Duplicate content that can’t be canonical
  • ✅ Thin/low-value pages
  • ✅ Private content
  • ✅ Search results pages (site search)

X-Robots-Tag (HTTP Header)

For non-HTML files (PDF, images):

X-Robots-Tag: noindex, nofollow

Site Architecture & Structure

1. URL Structure

Clean, descriptive URLs are better for UX and SEO.

URL Best Practices

Good URLs:

✅ example.com/seo-guide/
✅ example.com/blog/technical-seo/
✅ example.com/products/laptop-gaming/

Bad URLs:

❌ example.com/p?id=12345
❌ example.com/2025/12/15/post-title-with-unnecessary-date/
❌ example.com/category/subcategory/sub-subcategory/product/
❌ example.com/page.php?session=abc123&ref=xyz

URL Guidelines

  • Short: 3-5 words ideal
  • Descriptive: Indicate page content
  • Lowercase: Avoid uppercase
  • Hyphens: Use - not _ for word separator
  • No parameters: Avoid ? when possible
  • No stop words: Remove “the”, “and”, “or”, “of”
  • Static: Avoid session IDs, tracking params

2. Site Hierarchy & Navigation

Logical structure helps Google understand site organization.

Ideal Site Structure

Homepage (Level 0)
├─ Category 1 (Level 1)
│   ├─ Subcategory 1a (Level 2)
│   │   ├─ Product/Article 1 (Level 3)
│   │   └─ Product/Article 2 (Level 3)
│   └─ Subcategory 1b (Level 2)
│       └─ Product/Article 3 (Level 3)
├─ Category 2 (Level 1)
│   └─ Product/Article 4 (Level 2)
└─ Category 3 (Level 1)
    └─ Product/Article 5 (Level 2)

Structure Guidelines

  • Shallow over deep: Max 3-4 clicks from homepage to any page
  • Logical categorization: Group related content
  • Breadcrumbs: Show hierarchy
  • Internal linking: Connect related pages

3. Breadcrumb Navigation

Breadcrumbs show page hierarchy and improve UX + SEO.

HTML + Schema Implementation

<nav aria-label="Breadcrumb">
  <ol itemscope itemtype="https://schema.org/BreadcrumbList">
    <li
      itemprop="itemListElement"
      itemscope
      itemtype="https://schema.org/ListItem"
    >
      <a itemprop="item" href="https://example.com/">
        <span itemprop="name">Home</span>
      </a>
      <meta itemprop="position" content="1" />
    </li>
    <li
      itemprop="itemListElement"
      itemscope
      itemtype="https://schema.org/ListItem"
    >
      <a itemprop="item" href="https://example.com/seo/">
        <span itemprop="name">SEO</span>
      </a>
      <meta itemprop="position" content="2" />
    </li>
    <li
      itemprop="itemListElement"
      itemscope
      itemtype="https://schema.org/ListItem"
    >
      <a itemprop="item" href="https://example.com/seo/technical-seo/">
        <span itemprop="name">Technical SEO</span>
      </a>
      <meta itemprop="position" content="3" />
    </li>
  </ol>
</nav>

Benefits:

  • Shows in Google SERP (better CTR)
  • Improves internal linking
  • Better UX (users understand location)

4. Pagination

Handle multi-page content properly.

Pagination Methods

Method 1: Self-Referencing Canonical (Recommended)

Each page canonicals to itself:

<!-- On /blog/page/2/ -->
<link rel="canonical" href="https://example.com/blog/page/2/" />

Method 2: View All Page

All paginated pages canonical to “view all”:

<link rel="canonical" href="https://example.com/blog/all/" />

⚠️ Only if “view all” doesn’t hurt performance.

Method 3: Rel Next/Prev (Deprecated)

Google no longer uses this, but may help other engines:

<!-- On page 2 -->
<link rel="prev" href="https://example.com/blog/page/1/" />
<link rel="next" href="https://example.com/blog/page/3/" />

Pagination Best Practices

  • ✅ Include page number in title: “Blog - Page 2”
  • ✅ Don’t noindex paginated pages (waste content)
  • ✅ Internal link to paginated pages
  • ✅ Consistent URL pattern
  • ❌ Infinite scroll without pagination URLs

HTTPS & Security

1. SSL Certificate

HTTPS is ranking factor + trust signal.

Migration HTTP → HTTPS

Steps:

  1. Acquire SSL Certificate

    • Let’s Encrypt (free)
    • Paid SSL (more validation levels)

  2. Install SSL on Server

  3. Update Internal Links

    • Change all http:// to https://
    • Update images, scripts, stylesheets

  4. 301 Redirect HTTP → HTTPS

Apache (.htaccess):

RewriteEngine On
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Nginx:

server {
    listen 80;
    server_name example.com www.example.com;
    return 301 https://$server_name$request_uri;
}

  1. Update Google Search Console

    • Add HTTPS property
    • Submit new sitemap

  2. Update Canonicals

    • Point to HTTPS versions

  3. Test Mixed Content

    • Use browser console
    • Fix any HTTP resources on HTTPS pages

Security Headers

Implement via HTTP headers:

# HSTS (HTTP Strict Transport Security)
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

# X-Frame-Options (prevent clickjacking)
add_header X-Frame-Options "SAMEORIGIN" always;

# X-Content-Type-Options
add_header X-Content-Type-Options "nosniff" always;

# X-XSS-Protection
add_header X-XSS-Protection "1; mode=block" always;

# Referrer Policy
add_header Referrer-Policy "strict-origin-when-cross-origin" always;

Mobile Optimization

1. Mobile-First Indexing

Google primarily uses mobile version untuk ranking.

Mobile SEO Checklist

  • Responsive design (adapts to screen size)
  • Mobile-friendly navigation (hamburger menu, touch-friendly)
  • Readable font size (min 16px)
  • Tap targets 48px+ (avoid fat finger issues)
  • No intrusive interstitials
  • Fast mobile loading (target <3 sec)
  • Viewport meta tag configured
  • No Flash or unsupported plugins
  • Accessible form fields

Viewport Meta Tag

<meta name="viewport" content="width=device-width, initial-scale=1.0" />

Test Mobile-Friendliness

Tools:

  • Google Mobile-Friendly Test
  • Google Search Console → Mobile Usability report
  • Chrome DevTools → Device emulation

2. Responsive Design vs Dynamic Serving vs Separate URLs

Responsive Design (Recommended):

  • Same URL, same HTML, CSS adapts
  • Easier to maintain
  • Google’s preference

Dynamic Serving:

  • Same URL, different HTML for mobile/desktop
  • Requires Vary: User-Agent header
  • More complex

Separate URLs (m.example.com):

  • Different URLs for mobile
  • Requires rel=“alternate” and rel=“canonical”
  • Not recommended (legacy approach)

Duplicate Content Issues

Common Causes & Solutions

1. WWW vs Non-WWW

Problem:

http://example.com
http://www.example.com
https://example.com
https://www.example.com

Solution: 301 redirect all to one canonical version.

Apache:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule ^(.*)$ https://example.com/$1 [L,R=301]

2. Trailing Slash

Problem:

example.com/page
example.com/page/

Solution: Choose one format, redirect the other.

3. URL Parameters

Problem:

example.com/product?color=red
example.com/product?color=blue
example.com/product?sort=price

Solution:

  • Use canonical tags
  • Google Search Console → URL Parameters tool
  • Configure params in robots.txt if needed

4. Printer-Friendly Pages

Problem:

example.com/article
example.com/article/print

Solution: Canonical print version to main version.

5. Content Syndication

If you republish content elsewhere:

  • Request canonical back to your original
  • Use rel=“canonical” pointing to your version
  • Add delay (publish on your site first)

International SEO (Hreflang)

For multi-language or multi-regional sites.

Hreflang Implementation

<!-- English version -->
<link rel="alternate" hreflang="en" href="https://example.com/en/" />

<!-- Indonesian version -->
<link rel="alternate" hreflang="id" href="https://example.com/id/" />

<!-- English for US -->
<link rel="alternate" hreflang="en-us" href="https://example.com/us/" />

<!-- English for UK -->
<link rel="alternate" hreflang="en-gb" href="https://example.com/uk/" />

<!-- Default fallback -->
<link rel="alternate" hreflang="x-default" href="https://example.com/" />

URL Structure Options

1. ccTLD (Country Code Top-Level Domain)

example.co.id (Indonesia)
example.com.sg (Singapore)
example.com.my (Malaysia)

2. Subdomain

id.example.com
sg.example.com

3. Subdirectory (Easiest)

example.com/id/
example.com/sg/
