I have Page-A with canonical pointing towards page B. Page B should be considered the original and should be ranked in SERPS. But the Screaming Frog crawler is showing that page A and B are duplicating in term of their title and description. Why are canonicalized pages still be categorized by the crawler as duplicated in terms of h1, title and description etc?
One way to avoid the issue would be to use canonicalized + non-index (follow) but I believe it is not recommended. Why is it not recommended when it has more benefits like link value transferability, saving web's crawling budget and avoid duplication?
