For example there are some mons like Slowpoke or Kangaskhan that you can see right outside the wild area they spawn in so the best method is just spamming fast travel to that area
There are other mons who are present both day and night near a bench so spamming a on a bench is the best for them (area 20 alphas)
Some mons live in areas large enough that you can move in a predetermined path to de-and-respawn them like in Area 20 or the Mawiles and Sableyes in Area 9 . And others spawn in areas that are easy to fast travel to but only with specific battle zone spawns like Skarmory. So my advice is to pick a mon first and figure out the best way to make it respawn. You’ll know its being respawned if its gender and/or level change. There’s also some glitchy methods to increase spawn generations in specific areas but they are hard to set up.
