Unfortunately, that's a lot more tricky. If you're trying to rank both the .com and .sg version for, let's say, US residents, and those sites have duplicate content, then you do run the risk of Google filtering one of them out. If you use canonical tags or something like that, then one site will be taken out of contention for ranking - in that case, you won't rank for both sites on the same term. The only way to have your cake and eat it too is to make the sites as unique as possible. Even then, you're potentially going to duplicate effort and cannibalize your own rankings, so it's a risky proposition. In some cases, it may be better to try to promote your social profiles and other pages outside of your site that have some authority. It doesn't have to be your own site ranking, just a site that's generally positive or neutral.
