Your branded hashtags
That is usually #yourcompanyname or #companyinitials or a shortened version of your company name. You will have two or three of those and that is your branded hashtag.
The second type of hashtags are your product and/or niche hashtags. Maybe you have amazing hair care products. That might be #amazinghair. Or maybe your product serves a hobby market or a niche market like stand-up paddleboarder. You could use #SUP.
Finally, the third type of hashtags are the ones that are current or trending. These are truly relevant at that point in time. #bfcm (Black Friday, Cyber Monday) is a hashtag that ramps up around the holidays. Other holidays as well, #MothersDay, #FathersDay are great Instagram hashtags for makers marketing. And trending hashtags are not just holiday focused. They may only be popular one time and that is it.
These are the best hashtags for ecommerce and for business growth.
