My approach to being a Local Guide is to provide unbiased opinions regarding the things and places we go on a daily basis; I often give tips or insights beyond the basic star or “good” comment and I share what I genuinely experienced in that particular place
Based on feed-back people respond very well to this approach
I also love to post pictures that tend to show those places I visited in a different perspective, being very careful not including peoples faces or the like; most of them are wide angle pics… it must be working as one of them has 50k+ views
