Which sites you people use usually to track Pokemons for Pokemon Go?
pokesniper.org is best site.
Live website based Pokemon trackers and scanners site are never consistent as Niantic keeps on banning their service.
Anyways, at the moment I have been using these four and these have helped me in finding and catching many new and rare Pokemon:
3- Perth Maps (For Australia)
4- Montracker (Best for California)
If you guys know any other then please do share with us
