Question

How can I add a meta description in a list of pages of drupal in admin mode to improve my SEO ?

Answer 1

It's a pretty easy and direct solution.
You can just use the metatag module, to automatically generate the meta description. There is another option,  just manually add them for the range of pages. If you have any doubt just refer to this  article : https://www.drupal.org/project/metatag
