Here are a few things I do to find influencers in my region:
1. Go to local tourism pages/ local pages with large followings and look at photos they’ve been tagged in. A lot of influencers will tag large accounts hoping that their content will be re-shared, or that they will be seen by people looking through tagged photos.
2. Go to popular local hashtags and look at the top posts. Influencers use popular hashtags to be seen by more people, and because of their large followings they will often show up in the “Top” section when you click on a hashtag.
3. Go to your city/town/state geo-location and look at the top posts.
4. When you find a few influencers, look through their comments. Influencers will often comment on one-another’s posts.
I keep track of influencers by following them on Instagram, and I also keep a spreadsheet with a list of influencers in my area with data such as how many followers they have, what categories they fit into, location, contact info, etc.
Hope that helps!
