You only need a tiny number.The optimum is two or three. After that, the benefit drops off and it starts to look messy.
Use one niche tag
One location tag
Optional: one content type tag
That keeps your post tidy and still puts it in the right searchable boxes.
Tagging works differently and it is powerful for local creators. Tag one business per post
Only tag the one that appears in your video. Keep it clean. When a business sees themselves tagged, they are more likely to reply, re-share, comment, or follow.
That extra interaction bumps your post in the feed. It also helps the algorithm understand who your content is for.
Hashtags put you in search boxes.Tags create direct visibility with the people you want to notice you.
Use both lightly and with intention. That is the trick.
