The first units of the American Expeditionary Forces arrived in France on 26th June, 1917. Although until October 1917 only small forces engaged the enemy, by the end of the war in 1918 about 2 million US soldiers were in Europe, making the United States a major participant on the Western Front.
When President Woodrow Wilson decided to enter the war against the Central Powers in April 1917, the US military was far smaller than most armed forces active in the war. This was the main reason behind only limited American presence in France for long months to come. After a very slow buildup, US forces saw more and more action in greater and greater numbers.
While US forces were far from winning the war alone, the millions of fresh soldiers, and more importantly the massive industrial capacity of the United States was a decisive factor in an Allied victory. This help was especially important after the complete defeat of the Allies on the Eastern Front with Russia signing the treaty of Brest-Litovsk in March 1918.
The experiences gained by the Americans during World War I also came in handy during the mass mobilisation roughly two decades later during World War II: they didn't have to invent methods to restructure the economy to wartime production from thin air, as they had done it once during The Great War.
