Rel canonical on other page instead of duplicate page. How Google responds?

[vtmoz]

Hi all,

We have 3 pages for same topics. We decided to use rel canonical and remove old pages from search to avoid duplicate content. Out of these 3 pages....1 and 2 type of pages have more similar content where 3 type don't have. Generally we must use rel canonical between 1 and 2. But I am wondering what happens if I canonical between 1 and 3 while 2 has more similar content? Will Google respects it or penalise as we left the most similar page and used other page for canonical.

Thanks

Thanks for the answers and suggestions. I have more questions raised in my mind and I put them in the below different thread very clearly. Please reply there.

We know of a case from early 2017  in which Google stopped honoring rel=canonical for a large number of pairs of pages that were not verbatim duplicates.  Shortly after that all of those pages were indexed and displayed in the SERPs.

This sounds like you will be pointing/canonicalizing the two similar pages to the third one that is different from them? I am not quite sure why you would want to do that.

If you don't want the 1/2 content available but the pages have some authority (good links), 301 redirect those pages to 3 (if the topic is close enough and you don't have a more similar page) or if they are not strong pages, just remove them and let them 404.

If you do want the 1/2 content available on your site, but don't want it competing with page 3 in search, you could redirect 2 to 1 and rewrite 1 to make it stronger for whatever it is that makes it different from 3, so both 1 and 3 could potentially rank (for different things). Or you could redirect 2 to 1 and noindex 1.

Canonicals are intended for pages with very similar content, however people sometimes do use them as a type of redirect for not-so-similar pages. The problem with this is that a canonical is just a suggestion to Google and, as you mention, Google may ignore the canonical, especially in a situation like this.

HI,

Thanks for the immediate response. I agree with your analysis and conclusion. What if the duplicate page we are leaving is redirected to the page we are pointing?

I meant "1 will be pointed to 3 instead of 2" and "2 will be redirected 3"

How this works?

Thanks

I wouldn't do that.
By adding a canonical tag to the page you kind of tell google to ignore it. So, in this case, you have pages 1 and 2 with similar content and 3 with different content. You add canonical to page 3 referring to page 1. Google will now ignore page 3 (the one with different content) and will still index pages 1 and 2 which are duplicates.
You will not solve the duplicate problem, and you will also harm the unique page.
