How important is the uniqueness of internal pages among themselves?

Question

Search Engine Optimization

The site will have about 30 pages describing specific documents. The list of documents on these pages is 90% the same. Therefore, it is very difficult to make 90%+ uniqueness. What can you advise in such cases? How do search engines relate to not the best uniqueness of site articles among themselves?
It is desirable not to offer the option of combining all pages into one.

Answer 1

If these are normative documents or articles of the law and so on, then the uniqueness does not play a role.
At the same time, it is recommended to dilute such pages with functionality, such as, for example: surveys, comparison tables, user reviews and / or suggestions, questions “was the page useful”, linking blocks, and so on. That is, in your case, you need to take care not of uniqueness, but of the functionality and benefits of the page for the visitor, which distinguishes you from competitors for the better.
