Four minutes were required for AIK to take command against Gothenburg when Filip Rogic nodded in 1-0 on a well-beaten corner by Sebastian Larsson.
After that, the match picture became clear and Solnalaget never really let in blue and white so close.
Blåvitt had the most opportunities to score in fixed situations, but AIK fought hard.
The closest to reducing was the away team with eight minutes left of regular match time.
Alexander Jallow tested AIK goalkeeper Budimir Janosevic on a solid cannon, but after a fine parade, the score remained intact.
Before that, however, Henok Goitom had slammed in 2-0 and more or less decided the match with a nice shot from just over 25 meters.
The home victory means that AIK now has four straight victories and thus moved away from the bottom battle more and more.
For the Gothenburgers, it is more worrying as they only have three points down to Helsingborg and then the latter team also has one match less played.
