#1 You're still doing "Follow-for-follow"
Back in the day (okay really just a few years ago), it was very common to see people visiting each other's IG feeds and immediately commenting "Hey, follow for follow?". Meaning, they'd follow you if you follow them back. Even worse, sometimes, you'd follow someone only to realize weeks later that they've unfollowed you already and this was just a technique employed to grow their own numbers. This is not a winning strategy for growing your Instagram audience and will only stress you out. Instead, focus on building a long-lasting community of raving fans, aka "your tribe."
#2 You're posting too little
This probably could have been number 1, because it is the most common concern I hear from artists just starting to get serious about their social media. Many newcomers feel like they will turn people off if suddenly they ONLY share their creative pursuits or new venture. And even more so, many people fear that sharing 3-5 times per day is excessive. Yet, the reality is that we are being marketed to constantly and successful businesses understand that you must vie for your ideal market's attention. The best way to do this is to post frequently and consistently throughout the day to insure that at least one of your posts are seen that day.
#3 You're posting too much
Have you ever scrolled down your timeline only to see the same person sharing 3 or 4 photos within the span of a couple of minutes? It feels a bit spammy, right? It's like you haven't shared anything all week and you're trying to make up for it by flooding people's screens. I have certainly unfollowed accounts because of this and really advise against overwhelming people's feeds. It's much better to space out a few posts throughout the day since people check their phones multiple times of the day as well (as noted in the point prior).
#4 You don't have a vision for your feed
Some feeds are like a box of chocolates. You never know what you're going to get :P. Meaning it's all over the place and not in a good way! One minute there's a picture of a cat. The next day it's a weird mushroom you found in the woods during your morning stroll. And the next it's your latest outfit find from the mall. While it may be entertaining for the people closes to you, this isn't building a brand. Instagram is no longer a platform for personal blogging. If you run a personal blog, that is different. But for the rest of us, we can't be surprised when no one is pays attention to our art the one time we do share it. It's because they can't decide what's the most important thing on your feed and neither can you.
#5 You post selfies regularly
Everyone loves a good selfie. Indeed, Instagram is probably responsible for the creation of the term. If you treat your Instagram account like a personal blog, then selfies are more than okay. But for most of us, our audience and potential clientele would much rather see what you're working on than your face. Harsh, but true. But the beauty of this is that you can share quality photos even on days when you don't feel so glamorous because it's about your work!
#6 You don't take your photography seriously
Eventually, as you start to follow more and more successful accounts on Instagram you will develop a better eye for photography. You don't have to be a professional photographer, but some basic ideas on lighting, negative space, composition, and balance goes a long way. Interestingly enough, due to social media, we've become more selective in the quality of photo and video content we consume. So yes, the days of getting by with crappy photos on Instagram are over. If you haven't already, catch up!
#7 You rely on apps, comment pods, or paid shortcuts
This may be a bit controversial, so I will preface this by saying "to each his own." Whatever works for you at the end of the day, right? Paying for followers and other quick-fix apps is certainly a route that many people choose to take. If you've made the decision, however, to build an engaged and loyal community, then it's going to take a bit more strategy and patience.
