I use Instagram, daily, but I would not say I'm addicted to it, It's just a couple of minutes throughout the day, and in terms of business for Instagram, it's a great way to attract attention but there are many factors, that could help with advertising on Instagram, depends on the niche in mind. If you've influencers that support your product, it will gain a lot of impressions and people will click your page, if you're selling products/items, they can see a selection of your products, directly there, without having to visit your website first, making it easier for the potential customers.
