We recommend that you create segments to break down your traffic into 3 sources of traffic: branded, competition, and generic.
Branded traffic occurs when consumers know your brand
Add the keywords linked to your brand and your own ASINs
Competition traffic occurs when customers know your competitor's brand
Add the keywords linked to your competitors and their ASINs
Generic traffic occurs when consumers are searching for keywords that apply to the market.
Add the keywords that are linked to your products but not linked to your brand.
Beware to put keywords and ASINs in only one segment at a time.
Example
Let's say you sell toothpaste through the brand GoldTeeth and your main competitor is SilverDent.
Branded traffic occurs when consumers :
Search for “GoldTeeth”.
Browse your product pages.
The segment branded contains the keyword 'GoldTeeth' as phrase matching.
Competition traffic occurs when consumers :
Searching “SilverDent”.
Browse your competitor’s product pages
The segment competitor contains the keyword 'SilverDent' as phrase matching.
Generic traffic occurs when consumers :
Browse for "toothpaste".
The segment generic contains the keyword 'toothpaste' as phrase matching.
You can be more granular on the competition traffic by creating a segment per competitor
