Well, this is a pretty common issue, and it can often be a bit confusing. What is it? How is it determined? Why are certain pages on my site being flagged as duplicates of one another? And most importantly, how do I resolve it if I find that this is something that I want to tackle on my site?
So first off, what is duplicate content? Essentially duplicate content is content that appears in more than one place on the internet.
But this may not be as cut and dry as it seems. Content that is too similar, even if it isn't identical, may be considered duplicates of one another.
When thinking about duplicate content, it's important to remember that it's not just about what human visitors see when they go to your site and compare two pages.

It's also about what search engines and crawlers see when they access those pages.
Since they can't see the rendered page, they typically go off of the source code of the page, and if that code is too similar, the crawler may think that it's looking at two versions of the same page.
Imagine that you go to a bakery and there are two cupcakes in front of you that look almost identical. They don't have any signs. How do you know which one you want?
