I sell products to totes different audience eg mom of teenager daughter, husbands, at least 10 different audiences

1. should I put everything in one group or split into ad groups ?

2. On what basis should I split into diff ad groups?? instinct tells me shouldn’t be audience group as it will be too thin. Can you give me an example eg selling athletes shoes how would you split into ad groups

3. Also how many keywords should I have in each ad group? i noted the more keywords you have the lower max CPC - how should I structure this?

thanks
