🚨 November 2025 Google Update

On November 6, 2025, Google Search Central released official guidance on technical SEO audit methodology. Key takeaways:

  • Focus on prevention, not arbitrary scores. Technical audits should prevent issues from interfering with crawling/indexing--not just generate lists of findings.
  • Avoid tool score obsession. Many automated tools produce scores without contextual interpretation, leading to recommendations that don't address actual site-specific needs.
  • Prioritize Google Search Console data. Real indexing and crawl data matters more than synthetic test scores.

What Is a Technical SEO Audit (And Why It Matters)

A technical SEO audit is a systematic, comprehensive assessment of your website's technical elements to identify issues like slow site speed, under-optimized metadata, 404 errors, incorrect canonical URLs, crawl errors, and more.

Think of it as a health checkup for your Shopify store's infrastructure--diagnosing problems that prevent Google from properly discovering, crawling, indexing, and ranking your pages.

Why Technical SEO Audits Are Critical in 2026

🚫

Hidden Issues Kill Rankings Silently

Technical issues often go unnoticed until rankings plummet. A misconfigured robots.txt can block your entire store from Google. Failing to declare canonical versions can dilute link equity and confuse search engines.

⏱️

Crawl Budget Wasted on Low-Value Pages

Faceted navigation and poor URL structure can create millions of low-value URLs that drain crawl budget. Google crawls these instead of your important product pages.

📉

Core Web Vitals Impact Rankings

In 2025, INP (Interaction to Next Paint) replaced FID as a Core Web Vitals metric. Poor technical performance directly affects your Google rankings and user experience.

🎯

Prevent Issues Before They Impact Revenue

According to Google's 2025 guidance, the purpose of technical audits is prevention--stopping issues from interfering with crawling or indexing before they hurt your business.

Google's 2025 Technical Audit Methodology

On November 6, 2025, Martin Splitt from Google Search Central released official guidance that fundamentally changes how we should approach technical audits.

The Problem with Traditional Audits

❌ What Google Warns Against

Technical audits frequently rely on automated tools producing arbitrary scores without contextual interpretation. This leads to:

  • • Prioritizing "100 scores" over actual business impact
  • • Following generic recommendations that don't address site-specific needs
  • • Wasting time on low-impact fixes while ignoring critical issues
  • • Chasing vanity metrics instead of solving real crawl/index problems

Google's Recommended Approach

✓ The Prevention-First Framework (2025)

1
Start with Google Search Console

Check real crawl and indexation data--not synthetic test scores. Focus on actual errors Google encountered while crawling your site.

2
Identify Blocking Issues

What's preventing Google from crawling or indexing your pages? Robots.txt blocks, noindex tags, server errors, redirect chains?

3
Fix Prevention Issues First

Prioritize issues that actively block crawling/indexing before optimizing for better performance or perfect scores.

4
Monitor Ongoing

Technical SEO isn't one-and-done. Set up continuous monitoring to catch new issues before they impact rankings.

Crawlability: Ensuring Google Can Access Your Pages

Crawlability is Google's ability to discover and access your pages. If Google can't crawl a page, it can't index or rank it--no matter how good your content is.

Critical Crawlability Checks

1. Robots.txt Configuration

What to check: A misconfigured robots.txt can sabotage your entire SEO strategy by blocking vital pages.

How to audit:
  1. 1. Visit: yourstore.com/robots.txt
  2. 2. Check for unintended Disallow: rules blocking important pages
  3. 3. Verify Sitemap declaration: Sitemap: https://yourstore.com/sitemap.xml
  4. 4. Use Google Search Console → Robots.txt Tester to validate
Common mistake: Blocking /collections/ or /products/ accidentally

2. XML Sitemap Quality

What to check: Sitemaps should include all product pages, category pages, and valuable content--while excluding low-value pages.

Shopify sitemap locations:
  • /sitemap.xml - Main sitemap index
  • /sitemap_products_1.xml - Product pages
  • /sitemap_collections_1.xml - Collection pages
  • /sitemap_pages_1.xml - Static pages
Pro tip: Submit sitemaps to Google Search Console with dynamic updates enabled for faster indexing

3. Internal Linking Structure

Google discovers pages through links. Orphan pages (no internal links pointing to them) won't be crawled effectively.

Check for: Products with zero internal links, broken links (404s), redirect chains (301 → 301 → 200)

4. Crawl Stats Monitoring

Google Search Console → Settings → Crawl Stats Report shows how Google crawls your website.

Watch for: Sudden drops in crawl rate, high % of crawl requests with errors, slow average response times (>200ms)

Indexation: Getting Your Pages Into Google's Index

Even if Google can crawl a page, it might not index it. Indexation issues are among the most common technical SEO problems in 2025.

How to Diagnose Indexation Issues

Google Search Console: The Indexation Dashboard

Navigate to: Indexing → Pages

This shows why certain pages aren't indexed with examples of affected URLs.

Indexed pages:Good ✓
Crawled - currently not indexed:Investigate
Discovered - currently not indexed:Critical issue
Excluded by noindex tag:Verify intentional

Use an SEO crawler (Screaming Frog, Sitebulb) to find what's stopping proper indexing--then fix those specific issues.

Common Indexation Blockers

1. Noindex Tags (Accidental or Leftover)

Check for <meta name="robots" content="noindex"> in your page source. Often added during development and forgotten.

2. Canonical URL Points to Different Page

If your canonical tag points to a different URL, Google won't index the current page--it will index the canonical version instead.

3. Thin or Duplicate Content

Google may choose not to index pages with minimal unique content or content that duplicates other pages on your site.

4. Password Protection or Access Restrictions

Pages behind login walls, password protection, or IP restrictions won't be indexed. Verify your store isn't in "password protection" mode.

Canonical URLs & Duplicate Content Issues

Failing to declare canonical versions can mean lost rankings, diluted link equity, and wasted crawl budget. Canonicalization is one of the most critical technical SEO elements in 2025.

What Are Canonical URLs?

A canonical URL is the "preferred" version of a page when multiple URLs show similar or identical content. It tells Google: "This is the version I want you to index and rank."

Example: Shopify Duplicate URL Problem

A single product can be accessible through multiple URLs:

  • yourstore.com/products/blue-t-shirt
  • yourstore.com/collections/men/products/blue-t-shirt
  • yourstore.com/collections/sale/products/blue-t-shirt

Without canonicals: Google sees 3 separate pages competing for the same ranking.

With canonicals: All 3 point to /products/blue-t-shirt as the primary version.

How to Audit Canonical Tags

  1. 1.
    View page source (Ctrl+U) and search for rel="canonical"
  2. 2.
    Check that it points to the correct URL (not a different variant or version)
  3. 3.
    Use Screaming Frog to crawl your entire site and export canonical URLs for analysis
  4. 4.
    Look for conflicts: Pages with noindex + canonical (sends mixed signals)

✓ Shopify Good News

Shopify generates proper canonicals by default for its sites. However, they can be customized (and broken) by developers. Always verify canonical tags after theme changes or custom development.
