Our affiliate program tracks referrers by grabbing a variable in the link that was clicked, e.g. domain.com/index.php?ref=MRSMITH
At the moment all those links get a 301 and is redirected to the same page without the variable. I believe I read somewhere that it might be seen as cheating by redirecting link juice from a great many pages to one single (or a few) page(s). It does somehow sound credible... Should I switch to a 307 instead?
