Hello

I have just discovered this automated job : Index Search Engine - Updates
And I see that I've never runned it.

Does running it improve SERP rankings ?
My website has strongly improved in SEO and I don't want to run it if useless.

Could a Concrete5 staff tell us more about what this automated job does and why it is useful ?
And if useful, why isn't it automatically automated from time to time ?

Thanks a lot
