Your content is great, but rankings just won't budge?
The problem might be technical SEO. Many people create excellent content but overlook their website's technical foundation — like building a beautiful house but forgetting to install electricity and plumbing.

Indexability Check
This is the most fundamental check — ensuring Google can find and index your website.
☐ Verify robots.txt Is Configured Correctly
How to check:
- Enter
yoursite.com/robots.txtin your browser - Confirm no important pages are accidentally blocked
- Confirm there's a Sitemap declaration
Common issues:
Disallow: /blocks the entire website- Important directories accidentally blocked
- Development-stage blocks left in place
Correct example:
User-agent: *
Allow: /
Disallow: /admin/
Disallow: /private/
Sitemap: https://example.com/sitemap.xml
☐ Check noindex Tag Usage
How to check:
- Review the "Coverage" report in Google Search Console
- Or use Screaming Frog to scan the entire site
Confirm:
- Important pages are not set to noindex
- noindex is only used on pages you don't want indexed (e.g., thank you pages, test pages)
☐ Confirm Important Pages Are Crawlable
How to check:
Enter site:yoursite.com in Google's search box
Confirm:
- The number of results matches expectations
- All important pages appear
- No pages that shouldn't appear are showing up
☐ Submit and Verify Sitemap
How to check: Go to Google Search Console → Sitemaps
Confirm:
- A sitemap has been submitted
- Status shows "Success"

Site Architecture Check
Good site architecture makes it easy for both search engines and users to find content.
☐ URL Structure Is Clean and Meaningful
Good URLs:
✅ example.com/technical-seo-guide
✅ example.com/blog/seo-tips
Bad URLs:
❌ example.com/page?id=12345
❌ example.com/p/2026/01/post-1
Key points:
- URLs contain meaningful keywords
- Words separated by hyphens (-)
- Avoid excessive length
- Avoid special characters
☐ Site Hierarchy Doesn't Exceed 3 Levels
Ideal architecture:
Homepage
├── Category Page
│ ├── Article Page
│ └── Article Page
└── Category Page
└── Article Page
How to check:
- Important pages are reachable within 3 clicks from the homepage
- No "orphan pages" (pages with zero internal links pointing to them)
☐ Use Breadcrumb Navigation
Example: Home > Technical SEO > Technical SEO Checklist
Benefits:
- Helps users understand their current location
- Helps search engines understand site architecture
- May appear in search results
☐ Build a Complete Internal Linking Structure
Key points:
- Related content links to each other
- Use descriptive anchor text
- Important pages have sufficient internal links

Security Check
☐ Using HTTPS
How to check:
- Does the URL start with
https://? - Does the browser show a padlock icon?
Importance:
- HTTPS is a Google ranking factor
- User trust
- Secure data transmission
☐ SSL Certificate Is Valid
How to check:
- Click the browser's padlock icon to view certificate information

If you don't have SSL: Most hosting providers offer free Let's Encrypt SSL certificates.

Problem: HTTPS pages loading HTTP resources (images, CSS, JavaScript)
How to check:
- The browser Console will show warnings

Solution:

Check:
View the page source code and search for application/ld+json

Errors and Redirects Check
☐ 404 Error Pages
How to check:
- Google Search Console → Coverage → Errors
- Screaming Frog scan
How to handle:
- Important pages: Set up 301 redirects to relevant pages
- Unimportant pages: Ensure a user-friendly 404 error page exists
- Fix internal links pointing to 404 pages
☐ Are Redirects Correct (301 vs 302)?
When to use which:
- 301 (Permanent redirect): Page has moved permanently
- 302 (Temporary redirect): Page has moved temporarily
Common mistake: Setting permanently moved pages as 302, preventing full link equity transfer.
☐ Are Redirect Chains Too Long?
Problem: A → B → C → D (too many hops)
Impact:
- Each hop loses some link equity
- Increases load time
- Reduces crawl efficiency
Ideal: Redirects should go through no more than 1-2 hops.
