Runework (Rune Page Advice)

Long story short, I'm a Bronze 3 scrub who's been playing since Season 3. I've largely stuck to the basics when it comes to my Rune Pages and such, but as of late I'm looking to specialize and improve them a bit more, like how some people manage to work in CDR into their rune pages. I wanna generally improve my rune pages for all roles, but especially the solo lanes and jungle. Anyone willing to give some advice (or directions to such advice) on how I can make my rune pages- and thus the foundations of my early game performance- better and more specialized?
