The Shiny Pokemon, for the most part, look much different from the normal pokemon. Like Magikarp normally looks orange but the shiny ones look golden yellow.

Depending on the game, the base chance of running into a Shiny Pokemon in the wild is 1 in 4096 or 1 in 8192. A shiny charm makes you three times more likely to see one in the wild.

Also, your chances are high on community days. So get out on the community days for that month. Other than that just keep trying. Sooner or later one will be shiny.

Although there are many ways to obtain shiny Pokemon, it is difficult to judge which method is the best, because everyone's feelings are different. Some players don't have enough time to play this game, so they will choose to buy Cheap 6 IV Shiny Pokemon. I think this is the quickest way.
