Current

 * Guests' wishlist: With each new guests' first appearance, they would send in their hopes for trying classic segments of Weekly Idol (like Random Play Dance, This Corner's Star Is Me, etc.) or make a new segments just for them for future reference.
 * Fan's wishlist: Fan would send in hand-written notes a week before broadcast, then each member would answer their questions or fulfill their requests.
 * Weekly Playlist: Guests can perform a series of dance or song covers.
 * Weekly Flaylist: An altered segment just for a member of Fromis 9 to sing a cover of an English song regardless of the age of the song. This is one of the only times where the background of the set change to purple to reflect the group's reprentative color.

Pre-segment
Before "Idol of the Week", Weekly Idol had only one segment, "Real Chart! Idol Self-Ranking", where idols were asked to rank each other on different topics. This was later replaced by "I Wonder If You Know", where hosts, featured idols, Ilhoon (BtoB), and Bomi (Apink) guess one answer out of two choices given to them about idols, with food as a prize. This segment was replaced by "Weekly Food Tasting", where hosts, featured idols, Hayoung (Apink), Mina (AOA), and N (VIXX) complete mission to win foods they want. The following segment was "Idols are the Best", where various missions were given to the featured idols, namely Jackson (Got7), Jooheon (Monsta X), SinB (GFriend) and Dahyun (Twice).

A new segment was introduced on February 22, 2017, "Masked Idol: Your Name Is", where masked idols compete against one another: the winner gets to remove his/her mask and promote himself/herself and/or his/her group, while the rest have to attend the following week's contest alongside one new masked idol.

Main segment: Idol of The Week
The main segment of the show, called "Idol of the Week" (금주의 아이돌), features idol groups as the invited guests, and usually consists of several featured corners which vary from episode to episode:
 * Random Play Dance: the staff plays any songs that had been promoted by the guests randomly. A song usually stops at a random point or changes to another song while the guests must dance with the proper choreography for each song. It can also be shuffled from the same song or songs from the opposite gender (boy groups dancing to girl group songs and vice versa).
 * Profile Verification/Rewritten Profile: the guests comment their profile cards with the hosts, verifying or voluntarily proving the info before them.
 * Win Against Idol: the guests play a game together with the hosts. If the guests can beat the hosts, the winning side will get the special prize and the losing side will get the physical punishment from the winners.
 * Grill Idol: the guests must correctly answer some questions from the hosts; if they get the question right, they can eat the grilled pieces of Hanwoo beef that are prepared by the staff.
 * DoniConi Idol Call Center: a special call center is prepared for one week before the recording of an episode, and the fans can personally call in and leave messages for the guests; some messages are then revealed to the idols during the recording. Some fans ask the guests to perform a request.
 * Absent Member Call Center: a special call center where a member that is absent for any reason is called live, and they would be prompted to mention other members' names. The member mentioned the fewest times can get a prize. The first group trialled was EXID, Solji was the one receiving the call as she was still not medically cleared to return due to hyperthyroidism.
 * 99 Seconds Challenge: the guests need to succeed in a certain mission during a ninety-nine-second relay.
 * X2 Speed Dance Challenge: the guests must dance to one of their songs at double speed. It was first trialled on GFriend and is now one of the most popular segments.
 * This Corner's Star Is Me: the guests themselves decide the punishment in categories of when, where and what to do, and then play games to settle the final decision on each of the categories. The losing team (which is decided on the final battle) will carry out the punishment based on the categories.
 * X2 Speed Random Play Dance: a special segment trialled on GFriend, where they have to dance to a random selection of their own songs at double speed. They only have one chance to win expensive prizes.
 * Magic Choreography: the guests will be asked to fit choreography from one song to the music of another song. For example, when EXID danced their "Hot Pink" to "Mr. Mr." by Girls' Generation, or when they danced their "Up and Down" to "Mansae" by Seventeen, or when Red Velvet danced their "Russian Roulette" while lip-syncing to "Bubble Pop" by HyunA.
 * I AM a native speaker: A segment specifically for EXID due to the members' English abilities which vary greatly. Each member must give English clues for a word to German entertainer Dario without acting it out, and Dario can answer in either Korean or English. The member that gets Dario to answer the most questions gets a prize.
 * Back to Debut: A new segment in 2019, where a group dances to their debut song in original hair and makeup stylings, but with minor costume adjustments.
 * Do You Know This: A segment for younger idols born in the '90s or beyond, where they play a series of old playground games of the '70s to '90s. The winners of the best-of-3 series of games win a set of retro snacks.

An-hour special segment: Weekly Idol Award
During these corners, the talk is usually held without too much formality. An annual year-closing episode, Weekly Idol Award, started on December 31, 2011. In this episode, the hosts usually review the corners and the appearances of the guests that were featured in the latest year. In 2017, the Award show will be held outdoors.
