🔗 Canonical URLs

Protect your rankings by telling Google which SaaS page is the source of truth

💡 Why This Matters

A canonical tag (<link rel="canonical">) lets search engines know which URL should rank when multiple pages contain similar or duplicate content. Without it you can:

Split link equity across parameterized pages, staging domains, or UTM-tracked URLs
Trigger duplicate-content filters that suppress your primary pricing or feature pages
Confuse analytics and attribution when the same content lives at several URLs

Adding a single canonical tag preserves ranking signals and keeps your growth experiments from tanking organic traffic.

🎯 When You Need Canonicals

Any time the same content is accessible at multiple URLs (e.g., ?utm= parameters, /index, or localized query strings)
When marketing automation or A/B tools duplicate landing pages
When you syndicate blog posts or documentation to partner sites
When you have HTTP and HTTPS versions still reachable

🛠️ Step-by-Step Implementation

Step 1: Pick the canonical URL

Choose the cleanest, most authoritative version of the page. For most SaaS sites this is the HTTPS, www (or apex) URL without tracking parameters:

https://example.com/pricing

Step 2: Add the tag to `<head>`

Insert this between your other head tags:

<link rel="canonical" href="https://example.com/pricing">

Step 3: Keep it consistent

Every duplicate version of the page should point to the same canonical URL:

Example with parameterized URLs

// https://example.com/pricing?utm=launch
<link rel="canonical" href="https://example.com/pricing">

// https://example.com/pricing?ref=partner
<link rel="canonical" href="https://example.com/pricing">

✅ Validate

View source in the browser and confirm the canonical tag appears once per page
Use Google Search Console → URL Inspection to verify Google reads your canonical
Run a few affected URLs through Search Console after deployment

🚀 Advanced Tips

Self-reference canonicals even on unique pages to signal the preferred URL explicitly
One canonical per page: multiple tags cause Google to ignore all of them
Match protocols: canonical URLs should always use HTTPS if the page does
Handle paginated content: use ?page=2 canonicals carefully; often the first page is the canonical while subsequent pages use rel="prev"/"next"
Block alternate domains: staging or app subdomains should either 301 redirect or canonicalize to the production URL

📈 Expected Results

Consistent rankings for your core landing pages
Cleaner analytics as duplicate URLs consolidate into one
Faster indexation because Google understands the preferred URL immediately
