Fillers are being used to give the manga a time to run due to the author's having a problem with creating the plot of the ongoing manga. This is what happened in Bleach why Tite Kubo temporary breaks the anime series as he doesn't want to experience the same mistake he got on Hueco Mundo Arc & Fake Karakura Town Arc by giving too many plotted fillers, as well as ongoing mangas like Fairy Tail & One Piece presumingly, though they are still ongoing. Light novels have failed to do things like this making them have only last a few episodes by 12 to 24 or 26 at least like the ongoing series like Highschool DxD & Attack on Titan, & possibly other ecchi-themed ones like Hyakka Rouran Samurai Bride & Seikon no Qwaser, as their manga adaptations are still ongoing. The same goes with Black Butler as their biggest mistake is that they turned the first 2 seasons into a really poitnless yaoi not even matching the plot of the manga, making the reasons why BB fans like the manga more than the anime due to its failure.

Naruto's first fillers are indeed plotless as most of them are mission favors & replayed flashbacks of the first anime & are really boring. The ANBU filler has at least have a plot & more detailed reason for all these events & fans alike consider this a lot more canon. Some of the fillers are tend to be really more connected to the anime plot than in the manga as they didn't give much explanations such as where Sasori got his puppets which is shown in the anime. The best fillers in my opinion which I can claim to be canonical are 3-Tails Arc, Tsukigumo Arc & the ANBU arc as they got a point & explanation for the things they didn't show in the manga like Ukataka, Isobu & Kakashi's life as an ANBU.
