Here are practical, PrestaShop-specific steps to fix common Google Search Console issues. I will keep everything simple and directly applicable to PrestaShop sites.

---

✅ 1. Fix “Indexed, though blocked by robots.txt”

Cause

Your robots.txt is blocking URLs that Google still found.

Fix

1. Go to your PrestaShop back office.
2. Shop Parameters → Traffic & SEO
3. Click Generate robots.txt
4. Save.

If custom rules needed:

Allow important pages:

Allow: /modules/
Allow: /themes/

Do NOT block:

/product
/category
/content
/sitemap.xml

---

✅ 2. Fix “Duplicate Meta Descriptions / Titles”

PrestaShop sometimes creates duplicate titles for:

• Pagination
• Filters
• CMS pages

Fix

1. In Traffic & SEO → SEO & URLs
2. Edit Category, Product, CMS templates.
3. Use dynamic tags in Meta Title:

   {meta_title} | {shop_name}
   

Install free module:

✔ Pretty URL / Remove IDs module
✔ SEO Canonical URL Fixer

---

✅ 3. Fix “Crawled – Currently Not Indexed”

This happens when:

• Thin content
• Duplicate URLs from filters
• Slow website

Fix

(A) Disable “filter URLs” indexing

Go to:
Advanced Parameters → Performance → CCC
Disable “Friendly URLs for filters” if enabled.

(B) Improve content

Add 150–300 words unique text on:

• Category pages
• Important landing pages

(C) Speed Optimization

Use:

• Page cache module
• Image compression module
• Cloudflare CDN

---

✅ 4. Fix “Soft 404”

Google thinks your page has no value.

Fix:

• Add unique product description
• Add at least 1 image
• Avoid empty categories (add text + products)

---

✅ 5. Fix “404 – Not Found”

Occurs when products deleted or URLs changed.

Fix options:

A) Redirect using PrestaShop

Go to:
Shop Parameters → Traffic & SEO → Redirects

B) Use .htaccess

Example:

Redirect 301 /old-product-url/ https://example.com/new-product-url/

C) For deleted products

In PrestaShop → Product page → Redirect when deleted
Choose:
✔ Redirect to category
✔ Redirect to similar product

---

✅ 6. Fix “Server Error (5xx)”

Caused by:

• Hosting issues
• PHP memory limit
• Bad modules

Fix:

1. Increase PHP memory limit to 512MB
2. Disable recently installed modules
3. Regenerate .htaccess
4. Check hosting error logs

---

✅ 7. Fix “Mobile Usability Errors”

Such as:

• Text too small
• Elements too close
• Content wider than screen

Fix:

1. Switch to a responsive theme (Warehouse, Transformer recommended)
2. Test pages:
   Use URL Inspection → View Tested Page → Screenshot
3. Fix CSS issues:

   img, iframe { max-width: 100%; height: auto; }
   

---

✅ 8. Fix “Schema Markup Errors”

Usually caused by theme modules.

Fixes:

• Use Google Rich Snippet Module
• Use JSON-LD schema generator module
• Ensure product schema has:
  • name
  • image (use ImageObject)
  • price
  • availability
  • SKU
  • brand
  • offers

Let me know — I can generate optimized Product + Category + Breadcrumb JSON-LD for your store.
