page indexing sometimes increase or decrease in google webmaster why?

🔄 Why Page Indexing Increases

Index count may increase when:

  1. ✅ You publish new pages/products/blogs
  2. ✅ Google discovers previously uncrawled pages
  3. ✅ Sitemap updated correctly
  4. ✅ Internal linking improves
  5. ✅ Crawl errors fixed

For example, if you add new products on SOA Technology or optimize category pages, indexing will grow.


🔻 Why Page Indexing Decreases

Index count may drop due to:

  1. ❌ Pages removed or deleted
  2. ❌ Noindex tag added accidentally
  3. ❌ Canonical tag pointing to another page
  4. ❌ Duplicate content detected
  5. ❌ Crawl budget issues
  6. ❌ Server downtime / 5xx errors
  7. ❌ Soft 404 errors
  8. ❌ Google algorithm re-evaluation

Sometimes Google de-indexes low-quality or thin pages automatically.


⚠️ When Should You Worry?

You should check deeply if:

  • Sudden large drop (30–50% pages lost)
  • Important money pages not indexed
  • “Crawled – Currently Not Indexed” increasing fast
  • “Duplicate without user-selected canonical” errors

Small fluctuations (5–10%) are normal.


📊 What You Should Check in Search Console

Go to:
Indexing → Pages → Why pages aren’t indexed

Look at:

  • Excluded pages
  • Crawled – currently not indexed
  • Duplicate
  • Discovered – currently not indexed

🛠 For E-commerce or Business Sites (Like Yours)

Common reasons for fluctuation:

  • Filter URLs
  • Pagination URLs
  • Search URLs
  • Auto-generated product variations
  • Parameter URLs

Make sure:

  • Proper canonical tags
  • Clean sitemap (only indexable URLs)
  • Robots.txt not blocking important pages
  • No accidental noindex

🎯 Pro Tip (Important)

Index count going down is NOT always bad.

Sometimes it means:
Google removed low-quality pages →
Overall site quality improves →
Rankings improve.

Quality > Quantity.
