Farming is based both on trophies and your Town Hall level. You receive penalties for attacking towns that are more than one level below your Town Hall, so you’ll need to balance your level and your trophies. More on that later.
Protect your storage’s. Since you are farming for resources, you don’t want your spoils going to a lucky invader. Place your storage’s in the center of your town, surrounded by several walls and various defensive buildings. Place your Town Hall in your second layer of walls. This may seem like it will hurt, but that’s the whole point. It gives you more room in your base for storages. People will also attack you, and if you put it inside the walls, but not in the core, many attackers will go for the Town Hall, getting 30% which equals a free 13 hr shield. Putting your Town Hall in the corner is not good because a Town Hall is worth 2 storages now. Do not put your storage’s right next to each other. If you put them together, if the attackers get to your storage’s, they have gotten to them all. By spreading them out, you reduce your overall loss of resources. Place high-level resource collectors inside walls and leave the others outside. Keep checking the game after every 6 to 8 hours and collect the resources from the collectors.
Max out the upgrades for each of your defensive buildings, army buildings, and walls before upgrading your Town Hall. The best Town Hall level for farming is generally 5-7, but can definitely be applicable at the upper town hall levels as well.
Giants are expensive, so only worry about adding a few. Early levels should focus on Barbarian-heavy armies. Later levels generally call for more Goblins than anything else, though some strategies call for more Archers. As you increase your Town Hall Level, your maximum army size will increase, allowing for a greater unit variety, as well as a greater spell variety.
Pay attention to the upgrades you need next and focus on that resource.
If the town has gray league shields, then it has been inactive for at least the current season. If the Builder’s huts are “sleeping”, the player is likely neglecting the base. Look for round loot numbers. This usually indicates that the storages are empty by the collectors are full, which means that they will be easy picking.
Try to attack higher leveled collectors. Low-level ones might look full, but barely have any loot.
Use Giants as distractions since they can soak up lots of damage. Avoid deploying Wall breakers if a mortar is incoming.
You can forfeit battles after gaining the resources you need to ensure that you don’t get too high of a trophy count.
