Hi there! First off, make sure your account is set up to receive engagement. Make sure your profile is PUBLIC, make sure to include information about yourself and your business in the profile, and add a website (even if just a splash page) or contact info if you don’t have a website set up yet.
The best way to build your audience and following is by using hashtags with your posts. If you don’t use hashtags then only your current followers will see your posts on Instagram. All it takes is for you to do research on keywords related to your business, brand and target audience. You mentioned women’s clothing, so start by writing out all related words (such as: women, clothing, fashion, retail, etc…). Then you want to search via Instagram to see if these keywords are being used currently as hashtags. Use the ones with at least 100K posts, and then take a look at the feeds for the hashtags you search, and see who else is posting on there. Check to see what hashtags they are using.
Another great way for your industry to build momentum on Instagram is by working with fashion bloggers. Partner up with some popular or trending fashion bloggers on Insta (you can search terms such as ‘fashion blogger’ and then see who comes up as a top user); you can reach out and let them know about your clothing line and see if they’d be interested in featuring you to their followers.
There’s so much you can do to build a targeted following and also lead traffic back to your site. Keep it simple and keep it authentic.
I can help you even further by showing you more strategies to build a quality following and also coming up with great content to keep your followers engaged. Good luck and congrats!
