Apa Itu Crawlability?

  • Crawlability* adalah kemampuan search engine untuk menemukan, mengakses, dan crawl halaman di website Anda.

  • 3 Tahap Proses:*

  • Discovery - Googlebot menemukan URL (via sitemap, internal links, external links)

  • Crawling - Googlebot mengakses dan membaca konten halaman

  • Indexing - Google menyimpan halaman di database untuk ditampilkan di search results

Cara Kerja Googlebot

Googlebot adalah crawler (spider/bot) yang Google pakai untuk discover dan crawl website.

Crawl Process:

  • Start from seed URLs (sitemap, homepage, known URLs)

  • Follow links dari halaman yang sudah di-crawl

  • Download HTML dan parse content

  • Extract links untuk crawl selanjutnya

  • Repeat sampai crawl budget habis

Crawl Budget

  • Crawl budget* adalah jumlah halaman yang Googlebot crawl di website Anda dalam periode tertentu.

  • Faktor yang mempengaruhi crawl budget:*

  • Site authority - High-authority sites dapat crawl budget lebih besar

  • Server performance - Fast server = more pages crawled

  • Site size - Larger sites perlu manage crawl budget lebih hati-hati

  • Update frequency - Sites yang sering update di-crawl lebih sering

  • Untuk website kecil (<1,000 pages):* Crawl budget biasanya bukan masalah.

  • Untuk website besar (10,000+ pages):* Crawl budget optimization critical untuk ensure important pages di-crawl.

Robots.txt: Panduan Lengkap

  • Robots.txt* adalah file text yang memberitahu search engine crawler mana halaman yang boleh dan tidak boleh di-crawl.

Lokasi File

https://yoursite.com/robots.txt

File harus di root directory website.

Syntax Dasar

User-agent: * Disallow: /admin/ Disallow: /private/ Allow: /public/ Sitemap: https://yoursite.com/sitemap.xml

  • Penjelasan:*

  • User-agent: * - Berlaku untuk semua bots

  • Disallow: /admin/ - Block semua URLs yang start dengan /admin/

  • Allow: /public/ - Explicitly allow /public/ (override disallow)

  • Sitemap: - Tell bots lokasi sitemap

Best Practices Robots.txt

Jangan Block Halaman Penting

  • ⚠️ Bad:*
User-agent: * Disallow: /blog/

Ini block semua blog posts dari crawling!

  • ✅ Good:*
User-agent: * Disallow: /admin/ Disallow: /wp-admin/ Allow: /

Block Low-Value Pages

  • Pages yang sebaiknya di-block:*

  • Admin panels (/admin/, /wp-admin/)

  • Login pages (/login/, /signin/)

  • Thank you pages (/thank-you/)

  • Search result pages (/search?q=)

  • Filter/sort pages (/?filter=, /?sort=)

  • Contoh:*

User-agent: * Disallow: /admin/ Disallow: /wp-admin/ Disallow: /search? Disallow: /*?filter= Disallow: /*?sort=

Allow CSS dan JavaScript

  • ⚠️ Bad (Old Practice):*
Disallow: /css/ Disallow: /js/

Google perlu CSS/JS untuk render halaman dengan benar.

  • ✅ Good:*
Allow: /css/ Allow: /js/

Specify Sitemap Location

Sitemap: https://yoursite.com/sitemap.xml Sitemap: https://yoursite.com/sitemap-products.xml Sitemap: https://yoursite.com/sitemap-blog.xml

Bisa specify multiple sitemaps.

Common Robots.txt Mistakes

⚠️ Mistake #1: Accidentally Blocking Entire Site

User-agent: * Disallow: /

Ini block SEMUA halaman dari crawling!

  • Kapan ini OK:* Saat development/staging (tapi jangan lupa remove saat launch).

⚠️ Mistake #2: Blocking Important Resources

Disallow: /images/

Google perlu images untuk understand konten.

⚠️ Mistake #3: Using Noindex in Robots.txt

  • ⚠️ Bad:*
User-agent: * Noindex: /old-page/

Noindex bukan valid directive di robots.txt. Pakai meta tag instead.

  • ✅ Good:*
<!-- In HTML <head> --> <meta name="robots" content="noindex, follow">

Testing Robots.txt

  • Google Search Console:*
  • Go to Robots.txt Tester
  • Enter URL yang mau test
  • Click Test Tool akan show apakah URL blocked atau allowed.

Sitemap XML: Optimization Guide

  • Sitemap XML* adalah file yang list semua URLs di website yang Anda mau Google index.

Format Dasar

<?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>https://yoursite.com/</loc> <lastmod>2026-01-25</lastmod> <changefreq>daily</changefreq> <priority>1.0</priority> </url> <url> <loc>https://yoursite.com/blog/seo-guide</loc> <lastmod>2026-01-20</lastmod> <changefreq>weekly</changefreq> <priority>0.8</priority> </url> </urlset>

  • Elements:*

  • <loc> - URL (required)

  • <lastmod> - Last modified date (optional)

  • <changefreq> - Update frequency (optional, mostly ignored by Google)

  • <priority> - Relative priority 0.0-1.0 (optional, mostly ignored by Google)

Sitemap Best Practices

Only Include Indexable URLs

  • Include:*

  • ✅ Canonical URLs

  • ✅ Important pages (products, blog posts, categories)

  • ✅ Recently updated pages

  • Don't include:*

  • ⚠️ URLs dengan noindex tag

  • ⚠️ Redirected URLs (301/302)

  • ⚠️ Blocked by robots.txt

  • ⚠️ Duplicate content

  • ⚠️ Low-value pages (filters, sorts)

Keep Sitemap Under 50MB / 50,000 URLs

  • Limits:*

  • Max 50MB (uncompressed)

  • Max 50,000 URLs per sitemap

  • If larger:* Split into multiple sitemaps dengan sitemap index.

  • Sitemap Index:*

<?xml version="1.0" encoding="UTF-8"?> <sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <sitemap> <loc>https://yoursite.com/sitemap-posts.xml</loc> <lastmod>2026-01-25</lastmod> </sitemap> <sitemap> <loc>https://yoursite.com/sitemap-products.xml</loc> <lastmod>2026-01-25</lastmod> </sitemap> </sitemapindex>

Update Sitemap Automatically

  • For WordPress:* Use plugins like Yoast SEO atau Rank Math (auto-generate sitemap).

  • For custom sites:* Generate sitemap dynamically dari database.

  • Avoid:* Manually updating sitemap (error-prone).

Submit to Google Search Console

  • Go to Sitemaps section

  • Enter sitemap URL (e.g., sitemap.xml)

  • Click Submit

Google will crawl sitemap dan discover URLs.

Sitemap Types

Standard Sitemap (Pages)

<url> <loc>https://yoursite.com/page</loc> </url>

Image Sitemap

<url> <loc>https://yoursite.com/page</loc> <image:image> <image:loc>https://yoursite.com/image.jpg</image:loc> <image:caption>Image caption</image:caption> </image:image> </url>

Video Sitemap

<url> <loc>https://yoursite.com/page</loc> <video:video> <video:thumbnail_loc>https://yoursite.com/thumb.jpg</video:thumbnail_loc> <video:title>Video Title</video:title> <video:description>Video description</video:description> </video:video> </url>

News Sitemap

For news sites (special format dengan publication date).

Internal Linking untuk Crawlability

  • Internal links* adalah cara utama Googlebot discover halaman baru.

Best Practices:

Flat Site Architecture

  • ⚠️ Bad (Deep):*
Homepage → Category → Subcategory → Product → Variant (5 clicks)
  • ✅ Good (Flat):*
Homepage → Product (1-2 clicks)
  • Rule of thumb:* Important pages should be max 3 clicks dari homepage.

Avoid Orphan Pages

  • Orphan page* = page tanpa internal links dari halaman lain.

  • How to find:*

  • Crawl site dengan Screaming Frog
  • Filter pages dengan 0 inlinks
  • Add internal links dari related pages

Use Descriptive Anchor Text

  • ⚠️ Bad:*
<a href="/product">Click here</a>
  • ✅ Good:*
<a href="/product">Premium SEO Services</a>

Link to Important Pages More

Pages dengan more internal links = higher crawl priority.

  • Strategy:* Link to money pages dari:

  • Homepage

  • Navigation menu

  • Footer

  • Related posts sections

  • Breadcrumbs

Crawl Budget Optimization

For large sites (10,000+ pages), crawl budget optimization critical.

Strategies:

  • How:*
