What does 'Alternate page with correct canonical tag' mean?
An important but often overlooked element in SEO is the correct use of canonical tags.
These special HTML elements play a central role in preventing duplicate content problems by signaling to search engines like Google which version of a page is the “authoritative” or “canonical.”
“Alternate page with correct canonical tag” refers to an alternate version of a web page that uses the correct canonical tag to tell search engines which page should be considered the main version.
Google Search Console – Usage
Google Search Console provides deep insights into the way Google sees and interprets a website. One message that attracts positive attention is "Alternative page with correct canonical tag". This message signals that Google has detected another URL with the same or very similar content, but was able to correctly identify the preferred version of the page thanks to the correctly set canonical tag.
This finding is a strong sign that a website's SEO strategy is on the right track.
Below, we'll explore the basic meaning of canonical tags, the importance of reporting them in Google Search Console, how to apply these tags correctly, how to avoid common mistakes, and ultimately the benefit of this practice to a website's SEO performance.
Example 1 – canonical day
If a website has two different URLs, such as websitexyz.com/page/ and websitexyz.com/page/index.html, the canonical tag can be set on both pages to tell search engines that they represent the same page, thus avoiding duplicate content.
Example 2 – canonical day
For example, suppose your website has two different versions of a page, such as "websitexyz.com/product" and "websitexyz.com/product/?color=blue". Even though Google shows the second version, it uses the correct canonical tag pointing to the first version "websitexyz.com/product" to ensure that the correct page is indexed.
What is a canonical day?
A canonical tag (indicated by the rel="canonical" element in a page's HTML) is an instruction to search engines that indicates which version of a web page should be considered the "authoritative" or "canonical" version. This is especially important when similar or identical content is accessible via multiple URLs.

Why are canonical tags important?
- Avoiding duplicate content: They signal search engines which URL to index to avoid duplicate content issues.
- Concentration of link power: They help concentrate link equity on the canonical URL instead of spreading it across multiple duplicates.
- Improving the user experience: By ensuring visitors are directed to the preferred URL, they help ensure a consistent user experience.
- Increasing visibility: Correctly implemented canonical tags can improve a web page's visibility in search results by providing clarity about which content should be considered primary.
Tips for use
- Define clear preferences: Decide on a preferred URL for each group of similar content.
- Ensure accuracy: Make sure the canonical tag points to the correct URL, especially for websites that are accessible via multiple domains or protocols.
- Maintain consistency: Use canonical tags consistently across your website to send clear signals to search engines.
- Perform verification: Use Google Search Console and other tools to verify correct implementation and identify potential problems.
