Making reads on opponents

I know this is key for all levels and forms of poker but its just kind of hard to develop reads in sngs and mtts online with multiple games going on at the same time and such, I was just wondering for some tips and categories to label people and what each category means as far as what someone is likely and not likely to do. Any help would be appreciated.

i really am not an pro when it comes to omaha but my training did come from one. the biggest thing when it come to omaha hi/lo is that you should play only hand where you have a good chance to win both the high and the low. play all hands that have 3 to a low 5 or better or high hands that have all 9 or higher. don't over play AAxx it will just lose you money in the long run and don't raise and sometimes fold the low end of the str8. it is pretty basic after that. let me know if this helps at all .
