A key feature is a quiz dubbed "Find Your Smallmate" that matches buyers with the best small car for their needs and personality.
The lighthearted questions ask whether you are a kangaroo, cat or an owl and whether you like to win stuffed animals at amusement parks or go antiquing.
The "Spark is like the little blue puppy you always wanted," one response says.
The content is designed for younger car shoppers and allows them to "discover Chevy on their own terms," GM said in a statement on Monday.
"Small Talk," videos featuring the Sonic, Spark and Trax, are also part of the new small-car initiative.
Once they pick the correct vehicle, buyers can customize them with "whimsical features," such as rabbit ears, cool designs and backgrounds and then share it socially before they take the more serious step of visiting their Chevrolet dealer.
"Sonic, Spark and Trax customers are likely to be first-time new car buyers and traditionally are more likely to stay with the brand as their needs and lifestyle changes and they need to move up to a bigger sedan or SUV," said Steve Majoros, Chevrolet director of cars and crossovers, in a statement.
Edmunds says: Chevrolet has come up with a fun way to get the car-buying process rolling, especially for younger, socially savvy buyers.
