ACOS of 8 to 10% for Automatic Campaign is considered to be a good one.
First RULE: Negative Keywords
Negative Keywords are those keywords which cost you an extra penny without converting into a sale. Negative Keywords can be

Second RULE: Optimize Product Listing
To sustain the effect of sponsored products, the listings should be optimized for organic ranking.
Extracting the rare keywords from the search term report of the campaigns, positive keywords must be fed in the listing to rank higher on organic search.
Rare keywords help a lot in converting a view into a sale. Try to get as many as relevant rare and unique keywords for your product and fed them on the weekly basis.
I hope this might have helped you to optimize your automatic campaigns on Amazon.
