Doing a travel account aswell. It's a bit niched but not that much. I'm using "Instazood" to automatically like/comment related hashtags.
What I'm doing so far :
- Reposting HQ photo
- Good caption (it helps a lot for engagement)
- A good profile picture (it helps when they see your username in their feed)
- A good profile caption (what you're posting, tell them to tag you, etc)
- One or two posts a day
- Answer to as many people as possible
- Try to keep your followers/following ratio as big as possible (accounts that are following thousands of people look less attractive, atleast to me).
- Try to engage with similar accounts as someone suggested above
- Try to use attractive captions with questions, "tag a friend that you'd bring here", "did you know that..." It's working for me.
My journey with this account is pretty new. I'm around 2k followers only right now and I'm aiming 5k by the end of the year. Maybe I'll do a sort of website linked to it but I've got no idea of what I should put on it for the moment. (if anyone has tips I think we would be glad to hear

)
Hope it will help you, good luck !
