Don’t try to sell with every post. It could be way more successful to just provide value (can be related to what you’re selling, related advice, beautiful photos, you name it) without telling them to visit your shop and buy your products, and then have one post with a clear call to action mixed in from time to time.

People are annoyed with all the ads on Instagram, posts that try to sell something are being perceived as ads, even if they’re from an account they follow. Your followers will just scroll past if you try to sell with every post.
