When I was first learning about canonical tags, over ten years ago, I will admit that it is very confusing especially because at that time there was such little information about them. At first, I thought I would never us canonical tags because I didn’t plan to have duplicate content on my website or my client’s websites. But canonical tags are so much more than just tags you use to stop content duplication on your website it also helps with keyword cannibalization and similar content that is ranking for the same keyword. If you don’t do canonical tags correctly or at all it can confuse Google and hurt your rankings.
