Cache : Best Pratice

Hi,
Do you have any recommendations for optimizing the speed of the site with the Cache, both for Internet users and for Google?

In my controllers, I use the following line before returning my views:

PHP Code:

$this->cachePage(604800); 


Once the page is cached, it is displayed much faster for the users.

However, I have the impression that the Google Bot crawl is slower (I don't have enough log data to confirm this)

I also notice that the header returns :

PHP Code:

cache-control: no-store, max-age=0, no-cache 


Do you advise to change this? And if yes, what should I do?

If you also have recommendations to improve the overall performance, I'm interested

Ps : I use the file-based cache

Thanks in advance for your answer
