There are said to be over 120 factors that various SEs look for when determining where your website will appear in the rankings for a particular keyword/phrase.
Having a domain name with the keyphrase you are trying to target is one of those factors.
You state that you are "wondering how to optimize the redirected pages". This is a bit of a contradictory statement because a redirect by its very nature is not SE friendly! what is called a "301 redirect" is the friendliest
redirect, but no redirect passes all of the redirected URLs ranking power.
So, in my opinion, you would be best to optimize every individual domain for a different keyphrase and link into to your "mother" domain/website from all of these.
How do you optimise a website to rank? That's the million dollar question! This exact question has bred a multimillion dollar industry. Only the engineers from the varying SEs can answer this question fully, but here are a few main factors:
High quality content
Links from popular, related websites
your <title> tag
logical website structure
Nailing these factors will put you on track but i would encourage you to research the area of SEO more using affilorama and google.
