Instagram at the moment has been tough in terms of growing your account. With the algorithm no longer in chronological order, it means you're having to focus on high-quality images and promoting your photos to the best of your ability. I take my Instagram photos with my favourite blogging camera, my Olympus Pen E-PL7. I edit my photos mostly on Photoshop and create images like the one below on Canva. Once you've got the perfect images, you need to create a good caption and include the right hashtags. For beauty users you can hashtag brand names from products you've featured but aside from that there are plenty of hashtags that you should include. I've listed my favourites below in a handy Pinterest-friendly image.
