Why does my defense keep losing in Clash of Clans?

It is equally important to upgrade your walls along with upgrading your town hall. Many players upgrade the town hall to the maximum but do not upgrade the walls to the maximum, which is essential.

You cannot just keep air defenses your last priority to upgrade. As many players use dragons and air units as their army, we need to have robust air defense to tackle them.

The most significant aspect of this game is to maintain balance. If you lose balance, you lose against the attacker. This is what happens with many players of Clash of Clans, as they upgrade their town hall so early that they do not get a chance to upgrade their defenses appropriately, which leads them to lose the game.

You should always expect more influential players to speedily attack your base if you are advanced to a high league. It is better to wait, invest some time, and become eligible to compete in the advanced competitions to a particular league before you finalize you are entering those leagues.

It is vital to layout your village meticulously. You can still lose if your defense and town hall is robust, and your village layout is improper.  (See How to make a successful attack in Clash of Clans?)

Having large castle troops is a significant factor that facilitates destroying more massive armies more swiftly. One should make sure that they have adequate castle troops in their castle if their defenses lose often.

Splash Defences include Towers, and Mortars should be fully upgraded to help you become stronger and make the large group of enemies possibly lose against you. (See How to Defeat Clan Castle Troops in Clash of Clans)

Always make sure that any point of the map is covered by Mortar fire, air defenses, and of course, ground defenses. The attacker can easily find a vulnerable point of the missing gap if you are unable to maintain proper balance.

It is highly recommended never to store too much Gold or Elixir as they won't turn favorable. Instead, they will allure strong players towards your townhall and maximize the chances for you to lose. Hence, a player should manage and allocate their resources in a well-planned manner.

It is essential to ensure that your base is not surrounded by a single wall, as this will increase the chances of losing against the attacker. There should be at least more than a single level of walls in such a way that it becomes difficult for an attacker to reach important buildings that are elementary for the kingdom.

It makes it more accessible for the attacker to hit your townhall if you placed your defenses far from each other. Instead, it should be placed in a manner that the opponent finds no room for attacking, and it becomes harder for the attacker to destroy the village.
