If you want to push your Instagram account…

Try to make it your goal to get 100 followers. That gets to access to various metrics that you otherwise wouldn’t see.

Don’t just have people following your feed, but follow others and be somewhat interactive in doing so.

When posting, try to include location data and hashtags of the event and cars in the description. Also run a reel that includes photos from your posts.

Maybe save some photos as latergrams. Post some photos the week after the event you go to. I’ve found that Meta is more likely to show my initial photos quickly, but will meter or my later photos if I’m posting all at once.
