📖 What is Canonical Tag and Canonical URL?
When running a website, one of the biggest SEO challenges is duplicate content. Duplicate pages confuse search engines because they don’t know which version of your content to rank. This is where the canonical tag and canonical URL come to the rescue.✅ What is a Canonical Tag?
A canonical tag is a small piece of HTML code that tells search engines which version of a page is the “main” or “original” version.
For example:
<link rel="canonical" href="https://digitalmarketingwithbinod.blogspot.com/" />
✅ What is a Canonical URL?
A canonical URL is simply the preferred version of your webpage that you want search engines to index. It’s the page that should show up in Google results when people search for your content.
For instance, if your blog can be reached through:
-
https://yourwebsite.com/post -
https://www.yourwebsite.com/post -
https://yourwebsite.com/post?ref=123
You only want one main page to appear in search results. By using a canonical URL, you tell Google:
👉 “This is the original, please show this one.”
🔑 Why are Canonical Tags Important?
-
Avoids Duplicate Content Issues – Keeps Google from penalizing your site.
-
Improves SEO Rankings – All duplicate links pass their SEO value to the original.
-
Saves Crawl Budget – Helps search engines focus only on the most important pages.
-
Provides a Better User Experience – Visitors land on the correct, original page.
🛠️ When Should You Use a Canonical Tag?
-
When you have the same content available under multiple URLs.
-
For eCommerce sites with product pages that appear in different categories.
-
For blogs that can be filtered or sorted by tags and parameters.
-
For content that is republished on other sites but you want credit for the original.
📌 Best Practices for Canonical Tags
-
Always point to the most authoritative version of the page.
-
Use absolute URLs (with full
https://) instead of relative links. -
Avoid setting multiple canonicals on the same page.
-
Make sure every duplicate page correctly references the main URL.

If you want to keep your website healthy and SEO-friendly, always check your pages and set the canonical tag properly. It’s a simple step that makes a big difference in the long run.
