Social Rabbit: How do guys with General Store use Instagram Gallery Poster?

Hello Lovely people!

Some of you may have a general store with 3-4-5 niches.
I want to ask how you use auto gallery poster to Instagram? For example, you have different products from different niches; then while auto posting how you use hashtags? Hashtags should be specific to the product for more visibility.
- do you use same hashtags for every product that social rabbit is posting?
- Does it bring any traffic or make any impact? Or suggest any other way to insert specific hashtags related to the product, while social rabbit auto-post it.

Thanks in advance!
