This guide will explore the alternate page with proper canonical tags error, the reason for this problem, and how to solve it. By the end, you will have thoroughly comprehended the issue and know how to make your website’s pages properly indexed and optimized for search engines. So, let’s get started!

What Is Alternate Page With Proper Canonical Tag?

The “Alternate Page with Proper Canonical Tag” problem arises when Google finds multiple pages of your site with the canonical tag pointing to a particular URL. So, Google has located the same pages but with proper canonical URLs.

However, the search engine struggles to determine which to index and rank. This can result from several factors, including multiple URLs for the same content, using parameters in URLs, or having both HTTP and HTTPS versions of the page.

If it happens, the issue might lead to indexing troubles and, in turn, damage your website’s SEO results.

Reasons That Cause Alternate Page with Proper Canonical Tag Issue

Several factors contribute to the gap. But you need to understand that this does not affect the current page. If not, this problem is just a notice and not worth fixing.

  1. AMP version of web pages: If you have both AMP (Accelerated Mobile Pages) and non-AMP versions of the same content, it can cause an “Alternate Page with Proper Canonical Tag” issue. Here, the two versions possibly having the same canonical tag could confuse search engines.

  2. Protocol like www/non-www http/https: The different versions of your site’s URL that have both the “www” and “non-www” versions, as well as the “http” and “https” versions of the same page, can also be a reason why HTTP status errors occur. The search engine can recognize duplicate content with the same canonical tag.
