Sellers doing Business Pricing…What are your best practices?

I watched a Sophie Society YouTube video stating that this is the best thing since sliced bread to increase sales. https://www.youtube.com/watch?v=fH_yC6UQQiA

For sellers already doing this, what works and what doesn’t? Best practices?

1) Business Purchase activation? Percentage discount?

2) Then volume discounts? Percentage discount?

3) Campaigns with keyword bulk in the list of keywords? Bid Adjustment feature?

Thanks
