Leapfrogging
That is the short answer.
Admiral Nimitz and General MacArthur agreed on a two-pronged offensive loosely based on the War Department's prewar Plan Orange for war in the Western Pacific.
Nimitz' sailors and marines took the Central Pacific route, island hopping, bypassing enemy fortifications, establishing naval and air bases, luring the Japanese fleet into lopsided naval-air engagements heading for Taiwan to cut the maritime supplies to Japan.
MacArthur began in New Guinea and island hopped through the South Pacific toward the Philippines to which he had promised to return at the beginning of the war.
In the event, Nimitz opted for Iwo Jima over Taiwan. Both army and marine forces took part in the invasion of Okinawa where the tips of the pincers came together.
Artillery and machines guns caused armies to stay in defensive positions
The US did not have a strategy in the Pacific. There was little or no conflict in the Pacific in WW I, the military activity all took place in Europe.

When the US entered World War II in 1941, its strategy was to send most of its troops to the Pacific to battle Japanese forces. Later, from 1943-1945 the US led the allied war effort in Europe.
During World War II, the early major military strategy in the Pacific theatre was to stop the Japanese from approaching the United States by taking control of the Midway Islands. The European theatre was focusing on Africa to prevent enemy forces from moving northward.
"Europe First" strategy
Operation Cartwheel (1943-1944) was the major military strategy for the Allies in the Pacific theater of World War II. Cartwheel was a twin-axis of advance operation, aimed at militarily neutralizing the major Japanese base at Rabaul. The operation was directed by the Supreme Allied Commander in the South West Pacific Area (SWPA), General Douglas MacArthur, whose forces advanced along the northeast coast of New Guinea and occupied nearby islands. Allied forces from the Pacific Ocean Areas command, under Admiral Chester W. Nimitz, advanced through the Solomon Islands towards Bougainville. The Allied forces involved were from the United States, Australia, New Zealand, the Netherlands and various Pacific Islands

Only islands that were not well defended.
The Allied Forces did not have a strategy until after they were attacked because the Generals did not believe there was a major offensive going on in the Ardennes. This was to their peril. Since I am not a military strategist and do not know the military lingo I am sending you to some links to help you understand how the Germans and the Allied Forces fought the battle.
Island hopping, also called leapfrogging, was an important military strategy in the Pacific Theater of World War II. The strategy was to bypass heavily fortified Japanese positions and instead concentrate the limited Allied resources on strategically important islands that were not well defended but capable of supporting the drive to the main islands of Japan

Blitzkrieg was a military attack strategy designed by the Nazi Germans. The Allied Forces adapted this method too.

Yes, President Roosevelt did order the military to leave the Philippines and transferred the command of the allied forces in the Pacific theater to Australia.
