A typical 1 cup serving of frozen yogurt contains 7 grams of protein (4 g per 100 g), which makes it a good source of protein. That covers roughly 14% of the 50 g reference Daily Value, so it adds toward your protein total for the day.
Only about 10% of the calories in frozen yogurt come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
Among the 81 dairy foods in the database, frozen yogurt ranks 38th by protein per serving, and 378th out of all 796 foods on the site. Set against brick cheese, another dairy food entry in the database, a serving carries about 0.5 g more protein (brick cheese has 6.5 g per 1 oz).
It is a complete protein - it supplies all nine essential amino acids in adequate amounts, so it can carry a meal's protein on its own. The serving above is measured by volume at 175 g. The per-100 g figure lets you compare it directly against any other food here, whatever its serving.
Closer to ice cream than to cultured yogurt in composition.
