The URL is a very small part of over all SEO, and the ID at the end of your Odoo URLs are designed to be robust for the database and friendly for SEO right out of the box.

You are getting the primary SEO benefits (keywords and readability) while maintaining a stable site architecture - you can rename the name of the e-learning module or title of the blog page and you won't need to worry about changing the URL which is already indexed.

The URL influence is small compared to content quality, internal linking, and backlinks. In practice: keep URLs clean, human-readable, and stable. Beyond that, they have limited SEO impact.

With good PAGE SEO, you can easily get to the top of the rankings in Google without needing to replace or rename URL's.
