Hi Caroline, I believe the recommendations for placement are just the ideal placement, but I've put it elsewhere with success. You might add the munchkin where you're able, wait a bit, and then see if you have any anonymous visitors to your website (via a web page activity report in the analytics section). It's likely that they'll still be tracked and this will save you some headaches with having someone else add a code somewhere that you're unable to update/edit. (You won't need to update it often/ever, but it's nice to exclude a third party from the process.)
