Welcome to the Q&A Forum

I have a website with a lot of product pages - often thousands of pages. As each of these pages is for a specific lease car they are often only fractionally different from other pages. The urls are too long, the H1 is often too long and the Title is often too long for "SEO best practice". And they do create duplication issues according to MOZ. Some people tell me to change them to noindex/nofollow whilst others tell me to leave them as they are as best not to hide from google crawler. Any advice will be gratefully received. Thanks for listening.
