SEO impact of automatically translating a site into several language?

Hello Digital Friends,

For a site created with Wordpress, I just "added" 2 other languages to it with the TranslatePress plugin.
For the moment I am very satisfied with it because it is easy to use and allows me to change the url of the translated pages.

The Objective / Hope is:
- SEO: increase my number of pages on the site & inteal links and thus have a better ranking
- Increase Traffic : position myself on new languages and therefore new visitor traffic

I am right? or did i miss...
