controlling outgoing traffic among dual links BGP

Dear team,

What is the best approach to activate dual links load sharing or load balancing using routing protocol over the internet ?

If we have two ISP links coming to two routers and the ISP is using BGP to connect with us, what is the best approach to implement the following:

1- if we have equal links from ISP
2- if we have unequal links

How can we control the outgoing traffic to have the ratio for example 1:3 in case of unequal links.

Thanks a lot

The setup is the following:

Edge switch 2960 core switch 6509 ASA router
