There are a few schools of thought about where to place such pedals. In reality, there is probably no right way or wrong way - it is up to the individual.
The best advice I ever got, was to "try it and see". What works for one person with the gear they have may not work for another with different gear. Indeed, what two people want in terms of tone and sound will generally always differ.
So, have a go in the different positions and see which you prefer, which gives you the best tone - once you find that, then that is the right way (for you)
