Ref Codes In Backlink URLs?

I am putting up a website and I will be doing a lot of backlinking. Initially all of my backlinking will be outsourced and for my own future reference I want to use reference codes to see what traffic those backlinks bring in directly.

I know the big picture of backlinking it to move up organically but I'm also interested in knowing what direct traffic is coming from it.

My question is if I use two different reference codes will Google give link juice to the two urls as if they were separate? For instance lets say I backlink with a fivver gig for the url wwwdotmysitedotcom?ref=fivver and i backlink with dripable for the url wwwdotmysitedotcom?ref=dripable. Will these both give credit to my main website or will they individually give credit to the exact urls including ref code?

Thanks

Why don't you use 301's instead?

So have the pages with the ref codes redirect to the page without the ref code so google gives credit to the main page without the ref code? Or have different landing pages for each type of referral and have them redirect to my landing page? Or something I'm not thinking of maybe?

Sorry I am a little new to internet marketing itself. Currently I'm just a web developer learning the game. I'm sure this is another possible solution but it also didn't answer my initial question of if Google will give credit to the base url for both.
