And depending on your online interactions, you may want to consider levelling up your images on all the platforms you operate on. Let's put my photographer's bias aside for a moment, and I'll share a few thoughts as a Business Owner instead in relation to how I portray my online persona.
This is the most 'serious' of the platforms that I use. I take myself seriously, but not too much. I wanted my photo to be professional but fun because that's how I do my shoots. Part of this is also respecting the platform. It's business oriented. I treat it like a virtual office.
I have two personas on Instagram, one more 'formal' than the other. You'll notice that Ad Hoc Agent uses the same profile photo as LinkedIn but I don't have to and will likely be changing it soon. As a point of difference, Wool on Wheels operates at more of a community level and you'll see a big difference in the type of images I choose to use on each feed. That photo is overdue for a change too!
Instagram is all about the visual (and using the right hashtags). To be honest, I'm not using this platform to its full potential BUT there is more room for fun. I'm a big believer in sharing what I call the 'unhighlight' reel and this is the ideal space for bloopers and behind the scenes.
I don't use this platform so my opinion can be taken with as many grains of salt as you please. I guess it depends if you are on there as you, or as your business. If you are on there in a purely personal capacity with your nickname, then be as casual as you like. But if you're there as your business or representing your business and your handle reflects that, then I'd be using your logo or a close up professional photo as your icon image, appropriate to your profession.
I know it's easier said that done, but if your image is outdated or not purposefully taken for the platform(s) you're using, then I'd highly encourage updating it. I know how long it takes to get a good shot - especially if you are the person in front of the lens as well as behind it, but I won't leave you hanging. Next blog will be a tutorial you can refer to to sort out your own images at home using your smartphone.
