Since the Golems do small amounts of damage themselves, it´s important you bring high damage-dealing troops as back-up, like Wizards or Witches.
Golems aren't affected by Spring Traps. However, when one becomes two Golemites, the Golemites will be affected by Spring Traps.
If possible, destroy Inferno Towers as quickly as possible. Otherwise, they will wipe out your Golems. If the Inferno Tower is set on multiple target mode, it will not be much of a problem.
Golems, like Giants and P.E.K.K.As, are very high-health units that can be used to soak up fire. Make sure that the Golem is in the middle or in range of most of your defenses, as the Golem can distract attacking troops very effectively for a considerable amount of time. Even when overwhelmed, the Golem does a surprising amount of splash damage, enough to kill all Tier 1 and most Tier 2 troops (including lower-level Giants), as well as even Hog Riders. Any remaining attackers will then have to deal with the two Golemites as well.
The Golem has the highest hitpoints among all troops even at level 1, however, it has the lowest DPS per housing space among all troops even at level 5, even lower than Giant at 2.2 DPS per housing space.
