Your visuals aren't helping you, they're hurting you.
Your audience will first see your visual in a fast-paced feed, and not your caption. It's a thumbnail, cover image, first frame of a video or a graphic – it all depends on the one visual element that makes the person pause or continue scrolling. That's why even the best, most well-written content can burn out for lack of a good visual in the first second.
The images do not have to be professionally shot or you have to be a professional designer to make images that grab people's attention halfway down the scroll. A person needs only will to get it done. Employ colours in harmony with your brand to make your content instantly recognisable. Be sure that any text or information placed on your image is easy to read without zooming on a cell phone. Do not have too much going on in a scene; prevent eye drift. The most successful visuals are simple, clear, and striking in terms of what the viewer is about to see/read if they continue to watch/read past them. Your visual should be a promise, and you need to make sure to make that promise a reality with your content.
Especially video content should be given special attention. Short-form video keeps taking over, and the divide between creators who have dabbled in it and those who have jumped in it is widening. Going viral isn't the only way to get a return on investment from video — even more modest video content tends to outrank static posts in reach and engagement. Be easy on yourself, begin simple, become comfortable and work up from there. In the case of video, it's always better to be done than perfect.
Learn how to build a Personal Brand that people will remember.
To have Social Media presence is different from having a Personal Brand. Presence indicates being present on the web. A brand is a name that people recognize, a message that resonates with them and an understanding of what to expect from you before you even come up to them and say hello. It can take a while to achieve that kind of recognition, but it begins with a few intentional steps that many people don't even take.
The first step is to have a definite point of view. There is no need for another account with the same general information as all the other accounts in your niche. What is your opinion about your topic that others could challenge? What is your personal experience or point of view that will be unique to the project? That is your brand. Do this regularly and your content will begin to take a more unique approach.
Secondly, make yourself come across positively. People follow people – not logos. The better your audience understands who you are, the more loyal they will be to you, both within and beyond your humor, values, and problem-solving. Document the process of making the project behind the scenes. Acknowledge what did not go so well. Take joy in the little victories. It is far better to connect with people on an authentic level than a perfect level, and it's that connection that will bring them back long after you've moved off the algorithm.
